    Scaling of internal wall temperatures in enclosure fires2015In: Journal of fire sciences, ISSN 0734-9041, E-ISSN 1530-8049, Vol. 33, no 2, p. 113-141Article in journal (Refereed)
    Abstract [en]

    Physical scaling is an efficient and cost-effective modeling tool to be used in fire safety engineering. Scaling of internal wall temperatures was investigated in room fire tests in three different scales, that is, full scale (1:1), medium scale (1:2), and small scale (1:3.5). The fire sources were either placed at the center or in the corner of the enclosures. The measured time-dependent internal wall temperatures, incident heat fluxes, and gas temperatures in different scales are compared and analyzed. Test results show that the proposed scaling method is able to scale the internal wall temperatures (temperatures inside the walls) and incident heat fluxes well, especially in medium scale.

    Analysis of mortars with additives2005Report (Refereed)
    Abstract [en]

    Existing methods for the analysis of masonry and rendering mortars were developed for the analysis of well defined simple mortars. Mortars used today are to a large extent hybrid mortars with different additives and filler. Analysing complex mortars with additives and fillers requires analytical routines that are more versatile. In order to investigate the possibilities for characterisation of mortars using chemical and microscopical methods, test prisms were produced from lime cement mortars with dolomite filler and from lime cement slag mortars. After six months of hardening, the prisms were prepared for chemical and microscopical thin-section analysis. Acid-soluble components in the samples were analysed chemically and the constituents were quantified by optical microscopy using point counting and counting in fields. From these results the mix proportions were calculated. The chemical methods gave an assessment of the mix proportions calculated using a general algorithm. The calculation of the quantitative results based on microscopy was done according to the NT BUILD 370 method and the TNO method. These gave a good assessment of the lime cement mortars and the slag mortars with low slag content. However, the analysis of mortars with high slag content gave aggregate-binder ratios that were too low. The obtained results show that the combination of microscopical and chemical methods can provide a good assessment of the proportions used when mixing the mortars. Key words: mortar lime cement slag chemical microscopical

    Assessment of mechanical durability properties of rock materials using quantitative microscopy and image analysis2003Report (Refereed)
    Abstract [en]

    This report presents a project that focuses on the assessment of mechanical durability properties using quantitative microscopy. The project was financed by SGU under grant 03-1174/98. The aim has been to develop methods for assessment and presentation of rock quality data. Both optical and SEM/BSE microscopy were applied and combined with computerised image analysis and manual methods for the quantitative analysis. The first part of the project was to produce a literature overview of image analysis as applied to rock materials. A method for assessment of resistance to fragmentation of granitic rocks comparable with the Los Angeles test has been developed. By means of a quantitative description of foliation using a foliation index, FIX, it is possible to assess the potential length-thickness ratio of the crushed aggregate. Methods developed in the main part of the project have been applied in related areas. These include crack initiation and propagation under cyclic loading and cyclic thermal stress.

    Fire Test of Profile Plank for Transformer Pit Fire Protection2014In: Fire technology, ISSN 0015-2684, E-ISSN 1572-8099, Vol. 52, no 2, p. 309-319Article in journal (Refereed)
    Abstract [en]

    In general it is recommended to fill a transformer pit with rock ballast to extinguish the fire if there is a leakage of burning transformer oil. There is a lack of technology-neutral performance requirements for the design of solutions for fire extinguishment in transformer pit fires. This hampers the introduction of alternatives to the traditional method of filling the pit with rocks. Therefore we have conducted quantitative tests where temperatures and concentrations of CO, CO2, and O2 were measured at different position in a transformer pit subjected to burning oil simulating an accidental rupture and leakage. The tests were conducted to investigate the extinguishing capacity of one specific alternative solution, i.e. a profile plank layer over the pit. Three tests were performed with 90°C and 140°C pre-heated transformer oil. In the second test, a 19 cm water bed was used to examine the impact of rain water in the pit. The result showed that the profile plank extinguished the flames in a few seconds and that the water level did not have any significant effect on the result. The measurements showed that the temperatures peaked at 600–800°C 50 cm above the profile plank in all tests but dropped to under 100°C in 14–16 s. Furthermore the O2-concentration dropped to 3–5 vol% below the plank, which contributed to the rapid extinction of the burning oil.

    Evaluation of Two New Methods: APEI for inspection of Post-Tensioned Reinforcement and RSIM for Monitoring of Concrete Structures2006Report (Refereed)
    Abstract [en]

    This report presents the results from the evaluation of two new methods – APEI (Advanced Portable Equipment for Inspection) for in-situ inspection and RSIM (Real-time Structural In-service Monitoring) for in-service monitoring of concrete structures. Both the methods are based on the ultrasonic techniques and were developed in the EU-project “SGIM-2001”. The evaluation results show that the APEI system does, at the present status, not reach the target performances given in the specific objectives. However, it has been demonstrated by the other partners in the EU-project that the system worked in a homogeneous media (water tank) and, when using echo-reflection from a signal test surface, the instrument could detect a variety of targets in concrete samples. This is a necessary step in proving the correct operation of the system and also encouraging step for the future development of the operational system. The overall conclusions from the evaluation of the RSIM system are positive: the method was found to have good sensitivity to structural changes in concrete beams caused by over-loading and corrosion of internal steel. Artificial neural networks were found to work well in detecting significant structural changes. All development tasks and the majority of evaluation tasks were completed successfully. There were, however, problems associated with long-term reliability of sensors, especially under the severe cold weather. The size of sensors seems too big to be easily handled. Therefore, the RSIM sensor needs to be re-engineered to be smaller and more reliable. More valuation tests would also be desirable.

    Kartläggning av armeringskorrosion i betongstommar2005In: Bygg & Teknik, no 2, p. 25-28Article in journal (Other (popular science, discussion, etc.))
    Abstract [sv]

    Armeringskorrosion är en av de vanligaste orsakerna till skador på armerade betongstommar som är utsatta för karbonatisering eller kloridhaltig miljö. Ett typiskt exempel är bärande väggelement i vägtunnlar, som ofta exponeras för tösaltad miljö i nordiska länder. För bedömning av betongstommars tillstånd och för planering av erforderligt och kostnadseffektivt underhåll är det nödvändigt att kartlägga förekomst och utbredning av armeringskorrosion genom att använda snabba och enkla metoder med tillfredsställande noggrannhet. En sådan rationell, nyutvecklad teknik publicerades i Bygg & teknik (7/03). I denna artikel presenteras en praktisk tillämpning av denna teknik för kartläggning av armeringskorrosion i betongväggar i Söderledstunneln i Stockholm.

    Methodology of inter-comparison tests and statistical analysis of test results. Nordtest project 1483-992000Report (Refereed)
    Abstract [en]

    This report describes how to organise inter-comparison tests and how to statistically analyse the test results. In this report, relevant definitions, instructions, requirements and criteria from ISO, ASTM, EN standards, as well as national specifications are summarised and some examples of inter-comparison tests from practical applications are presented. The definitions of various terms commonly used in inter-comparison tests are given in Chapter 2. The complete procedures for organising inter-comparison tests are described in Chapter 3, while some useful statistical tools for analysing test results are given in Chapters 4 and 5. Practical applications of the precision test results are presented in Chapter 6 and, finally, the concluding remarks are given in Chapter 7.

    Use of small scale methods for assessments of risk for self-heating of biomass pellets2012Report (Refereed)
    Abstract [en]

    One major concern when it comes to storage of wood pellets is the risk for self-heating. The propensity for self-heating varies between different types of pellets. It also depends on how the pellets have been handled and on the storage conditions, e.g. the temperature and humidity. Within the framework of the research project “Large scale Utilization of Biopellets for Energy Applications –LUBA” different laboratory-scale methods have been used to study different thermal properties and the propensity for self-heating for different types of pellets. The different methods used include micro calorimetry also called isothermal calorimetry, basket-heating tests and transient plane source (TPS). In total 21 different pellets samples were tested in the micro calorimeter, three in the basket-heating test and three in the TPS. The samples showed significant differences in propensity for self-heating. Differences could be seen both between different types of pellets and depending on the age of the pellets. Comparing the reactivity rates from the basket-heating tests and those from the isothermal calorimetry tests with the same type of pellets, both methods gave the same ranking of reactivity. It was shown that the TPS-method is applicable for the determination of thermal properties both for measurements on single pellets and for measurement on bulk pellet material.
