    Pilot spark energy in the cone calorimeter: A source of measurement uncertainties2014Ingår i: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 38, nr 7, s. 760-764Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This work presents measurements meant to study the influence of the spark energy on the time to ignition of a given material in the cone calorimeter. For this purpose, square slabs of particle board were tested under two radiation intensities until ignition occurred using two spark energies for each intensity level. Results show that increasing the spark energy leads to a reduction inthe ignition time regardless of the radiation intensity. However, the influence of the spark energy on the time to ignition is, in absolute numbers, larger for the low radiation intensity case than for the high radiation intensity case. Nonetheless, the proportional difference is nearly 10% for both levels of heat radiation. Results from this work confirm that there is an influence of the spark energyon the time to ignition of a given material suggesting that a narrower and more specific definition of the ignition circuits allowed in the cone calorimeter would be highly beneficial for ensuring repeatable results among laboratories.

    Electrical currents and breakdown voltages as a diagnostic tool for fires2011Rapport (Refereegranskat)
    Abstract [en]

    Two types of electrical measurements have been investigated in order to perform diagnostics of the fire dynamics in the ISO 5660 cone calorimeter. The rationale of the study is to take advantage of the pilot ignition electrodes that are already in place and use these to collect additional information such as emission of pyrolysis gases and time to ignition. The first part of the project was a refinement of the method for measuring the so called ion current, which has already been investigated in a pilot study. It was found that thorough shielding and grounding gives an excellent signal to noise ratio. An expression for the correlation between measured current and conductivity was also developed and validated experimentally. The second part of the project consisted of measuring the breakdown voltage, that is the voltage when dielectric failure occurs. It was found that this method was more sensitive to the fire dynamics before ignition, such as pyrolysis, but that the response to ignition was more ambiguous for the breakdown voltage than for the ion current.

    Forsmark and Oskarshamn site investigtion Borholes Inter-laboratory comparison of rock mechanics testing results. SKB P-05-239.2006Rapport (Refereegranskat)
    Abstract [en]

    Abstract Laboratory testing of the mechanical and thermal properties of rock is a part of the activities Performed during the current SKB site investigations. The laboratory testing is being conducted at SP, (the Swedish National Testing Institute) and at other laboratories. The objective of this investigation was to evaluate the comparative accuracy and precision of the test methods for indirect tensile strength, uni- and triaxial strength, shear strength, thermal expansion and heat capacity as conducted at the different laboratories. The core samples were obtained from borehole KFM01A at Forsmark and KSH01A at Oskarshamn. A significant difference in the results from the different laboratories was detected for Poisson’s ratio, peak shear stress and thermal expansion. However, no significant difference between the laboratories’ results could be detected for thermal capacity, thermal diffusivity, thermal conductivity and compressive strength as determined in the uniaxial test. For Young’s modulus, residual shear stress and indirect tensile strength the differences are questionable. Investigations of causes for differences in the results are not part of the current commission. Although interviews with responsible personnel at the SP laboratories indicated that the reasons could be load application (interlayer) in the indirect tensile strength test, shear area and compensation for change of area during the shear test, stress level for calculation of the Poisson’s ratio and conversion of readings for measuring thermal expansion. Before any further investigation is performed, these differences between the laboratories must be examined further and eliminated. For future inter-laboratory comparisons of this nature, we recommend that the technically responsible at the laboratories go over the methods and the procedures (sample preparation, testing and data reduction) together, to identify and take care of the differences between the different laboratories. The thermal properties are measured by the same principle on equipment from the same supplier. It could therefore be of interest to compare the results with the results that are obtained by another measurement principle.

    Influence of rock and mineral properties on the durability of marble panels2004Ingår i: Proceedings of the international conference on Dimension Stone 2004, 14-17 June 2004, Prague, Czech Republic, Taylor & Francis Group plc, A.A Balkema Publishers , 2004, , s. 245-251Konferensbidrag (Refereegranskat)
    Abstract [en]

    The use of thin marble and limestone for facade cladding has increased substantially during the last five decades. The durability of such thin slabs (often only 30 mm thick) has been assumed to be satisfactory based on centuries of successful use as a structural building stone. Nevertheless, all over the world, the long-term deformation and strength loss of some claddings have led to concerns about its safe and durable use. The detailed assessment of marble and limestone within TEAM (see also www.sp.se/building/team), is used to develop a hypothesis for the observed deterioration and to develop remedial actions. This paper considers the influence of rock and mineral properties on the behaviour of marble claddings. A selection of results is presented, illustrating the influence of properties like mineralogy, grain size and boundaries, preferred orientation and pore structure. Of the intrinsic parameters, the interlocking of the grains and the lattice preferred orientation seem to be very important influencing factors. The final evaluation of the results will be presented in 2005.

    Abstract [en]

    The use of thin marble and limestone panels for facade cladding has increased substantially during the last five decades. The durability of such thin slabs (often only 30 mm thick) has been assumed to be satisfactory based on centuries of successful use as a structural building stone. Nevertheless, all over the world, the long-term deformation and strength loss of some cladding panels have led to concerns about its safe and durable use. The detailed assessment of marble and limestone within the TEAM-project (see also www.sp.se/building/team), is used to develop a hypothesis for the observed deterioration and to develop remedial actions. This paper presents test methods for the bowing and expansion potential of marble. The method is discussed and the relevance of the test exposures is demonstrated by comparisons with on-site observations on marble cladding. A number of results are presented, illustrating the influence of the temperature cycles, the humidity and the stonetype on the bowing and expansion.

    Testing and Assessment of Marble and Limestone (TEAM) - Important Results from a Large European Research Project on Cladding Panels2007Ingår i: Journal of ASTM InternationalPaper ID JAI 100855, Vol. 4, s. 14-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The use of natural stone as facade cladding has been shown to have much lower life cycle costs and they are more environmentally friendly than comparable products of concrete, glass, and steel. Promoting the use of natural stone has therefore a great positive impact on the environment. However, the number of occurrences of bowing and expansion of marble and limestone panels has led to increased maintenance costs, significant safety risk, and negative publicity. The lack of knowledge of a solution to the problem of bowing marble has a large negative effect on the entire stone trade. In response, short-sighted and less durable construction solutions are used as an alternative, adding to the decreasing export figures and numbers of employees within the stone sector. The TEAM _TEAM_TEsting and Assessment of Marble and limestone_ project addresses a problem with marble types, from several European countries, that display bowing on facades in both cold and warm climates. There is, therefore a need to develop harmonized European standards for differentiating between marble that is susceptible to bowing and marble that is not. Resolution No. 013, in May 1999 taken by the European Committee for Standardization _CEN_, Technical Committee _TC_ 246 Natural Stone states the urgent needs “to develop a direct test method of the bowing risk for marble cladding products.” Thus, the project addresses the mandate for external wall coverings and the safety of panels. This paper serves to give a comprehensive overview of the main findings in the project. The main objectives were: • To understand and explain the mechanisms of the expansion and loss of strength, probably the most important phenomena leading to degradation of marble and limestone clad facades. • To prevent the use of deleterious marble and limestone by introducing drafts for European standards. • To develop a concept for assessment of facades, including a monitoring system in order to predict strength development and improve safety and reliability. • To analyze if surface coating and impregnation could prevent or diminish the degradation. • To address quality control aspects in order to optimize the production conditions. The TEAM project consortium, representing nine EU _European union_ countries, comprised sixteen partners representing stone producers and trade associations, testing laboratories, standardization and certification bodies, consultants, building owners and caretakers and producers of fixing and repair systems. A state-of-the-art report has been written and is based on an extensive compilation of more than 400 papers on marble and limestone deterioration dating from the late 1800s to 2006. A survey of about 200 buildings has given a clear picture of the extent of the problem in geographical, geological, and climatological terms. Detailed case studies of six buildings have resulted in a methodology for assessment of facades including monitoring system and risk assessment. Research both in the laboratory and the field were performed on a large number of different stone types from different countries and used in different climates. This gave the explanation of degradation mechanisms and led to the determination of the critical influencing factors. Two tests methods, including precision statements: one for bowing _1_ and one for thermal and moisture irreversible expansion have been prepared for submission to CEN TC 246. Repair techniques based on the use of surface coating and impregnation systems has been tested at laboratory and in the field. Positive side effects including increased durability and easier cleaning have been observed. Guidelines for production and product control have been proposed, and an instruction for stone sampling and description has been developed.

    Duarability of Marble Cladding - A Comprehensive Literature Review2007Ingår i: Journal of ASTM International Vol 4 No 4, Vol. 4, s. 19-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Natural stone has been used for centuries as building material. In historical time it was mainly used as load bearing elements, but within the past 50 years a new processing technique has made it commercially feasible to produce and use thin façade cladding. Unfortunately, a number of marble facades on buildings in both Europe and elsewhere have had serious problems with deterioration of the stone material. The TEAM _TEAM _ TEsting and Assessment of Marble and limestone_ project consortium represents nine European countries and comprises 16 partners, representing stone producers and trade associations, testing laboratories, standardization and certificate bodies, consultants, building owners and caretakers and producers of fixing and repair systems. The project had a budget of approximately 5 million dollars and was partly funded by the European Commission under the contract no. G5RD-CT-2000-00233. Two of the main objectives in the TEAM project were: — To understand and explain the mechanisms of the expansion, bowing, and loss of strength leading to degradation of marble and limestone clad facades. —To prevent the use of deleterious marble and limestone by introducing a draft for new European standards. This paper presents some of the important conclusions drawn from a literature review carried out within the TEAM project—and was based on an extensive review of literature on marble and limestone deterioration dating from the late 1800s to 2006 and the results of the TEAM project. The comprehensive information from more than 70 selected literature references is reviewed and discussed in order to describe the present knowledge on the causes and mechanisms responsible for the bowing and strength loss of thin marble cladding. In the following, the literature and TEAM findings are grouped under a number of headings proposed to explain observations. Thus, the information from the literature is compared and supplemented with the results from the TEAM project in order to present a good overview of the existing, most relevant, knowledge in the field. The literature review reveals that only few researchers have examined the durability problem from a broad perspective. In addition, no conclusive answer about the mechanisms and influencing factors can be given. The TEAM project has made it possible to identify several of the key influencing factors in marble degradation, the relative importance of various factors, and to gain a deeper understanding of the mechanisms involved.

    Utvärdering av skillnader mellan provning av makadamballast enligt BVF 585.52 och EN 13450 - Underlag till ny svensk standard2004Rapport (Refereegranskat)
    Abstract [sv]

    As a step towards the introduction of the new European product standard SS-EN 13450 for Railway track ballast in Sweden, SP was given the commission to make a survey of older test results and compare testing of selected materials with test methods in accordance with the old and the new regulations/standards. Test results for the past 10 years, from most Swedish producers, were collected, evaluated and compared with the old and new requirements. 10 aggregates were chosen for a detailed study of almost all properties specified in the new standard. The outcome is a recommendation for properties to be declared and categories to be used in the new Swedish standard. The most difficult part is how to deal with conformity criteria since no such are given in EN 13450! It is not stated whether the categories shall be interpreted as absolute values or if they can be used to compare with e.g. characteristic values, mean values … It has also to be defined in a special document how old test results can be used for the conformity assessment. The following properties will be used in Sweden: Petrographic composition, Particle size distribution, Los Angeles Value, micro-Deval, Shape index, Water absorption and density. Depending on the value of the water absorption, a frost resistance test will also be required. For basalts of unknown origin, a “Sonnenbrand test” will most likely be required. Key words: Railway ballast, Standards, Aggregates, European standard, Swedish norms
