The definition of the post-fire properties of steel fiber reinforced concrete (SFRC) is a current technological challenge. A study conducted using the Barcelona test (BCN) show that the puncture caused by the test may result in crushing of the porous matrix and induced frictional interaction. This influence may result in misleading conclusions regarding the properties and the behavior of the composite, which denotes that an inadequate test methodology may significantly affect results of SFRC after temperature exposure. In this context, the Double Edge Wedge Splitting (DEWS) test is a promising methodology for this type of application since a mode I fracture type is induced in the specimen, diminishing any compressive or puncture interactions with the porous matrix. Therefore, this work aims to present the results obtained for SFRC exposed to temperatures of 25 °C and 600 °C by means of DEWS test. Results show that the tensile strength of the cement matrix and the residual tensile strength at the service limit state and ultimate limit state are significantly affected. Additionally, no visible damage was caused by the interaction between the roller and the SFRC for specimens exposed to 600 °C. The present study contributes to the absent literature on the residual tensile strength of SFRC after temperature exposure, and suggests an alternative test method to be employed.

In this work, an attempt has been made to develop and investigate mechanical and the fracture behaviour of ultra-high performance concrete (UHPC). Geometrically similar notched beam specimens of different sizes made up of ultra-high performance fibre reinforced concrete (UHPFRC) have been considered for the experimental investigation. Centre point bending tests have been performed on beam specimens in crack mouth opening displacement control manner for investigating the fracture properties. Various fracture properties such as, fracture toughness, fracture energy, brittleness number etc. have been determined on the basis of non-linear fracture mechanics theory. The results of UHPC concrete have been compared with that of normal strength concrete available in the literature. It has been observed that addition of fibres increases the energy absorption capacity to a great extent for all size of specimens of ultra-high performance concrete as compared to normal concrete. Moreover, the brittleness number has been found to decrease due to the addition of fibers thereby enhancing the ductility. A decrease in nominal strength of UHPC based concrete with the increase in specimen size has been observed in similar fashion as normal strength concrete. However, the sensitivity to the size effect of ultra-high performance concrete is effectively reduced compared with normal concrete.

Tensile behavior of fibre reinforced concrete is assessed based on flexural tests where specifically the post cracking strength values are of interest. However, the residual tensile strength values obtained based on such characterization test exhibit a very high scatter which is mainly due to the variation of number and orientation of fibres at the fracture plane. This rather unrepeatable behavior may cast doubt on the overall performance of a structure reinforced only with fibres and may question the validity of estimated tensile strength parameters that are used in the design of such from one specimen to another structures. While there is evidence that fibre reinforced concrete structures show a behavior that can be predicted by the average material properties, no strong proof is yet available. If so, then the low characteristic value of residual strength values may be a very conservative starting point for design of such structures To validate the reliability of design approach proposed for fibre reinforced concrete structures, twelve nominally identical fibre reinforced concrete slabs sized 2000×2000×150 mm, and twelve notched specimens sized 150×150×600 mm are tested, and the results are compared. Further, a yield line method is employed to predict the ultimate load bearing capacity of the slabs based on the tensile parameters obtained from the characterization tests. The results show that the average material properties can satisfactorily predict the bearing capacity of the slabs. FraMCoS X Conference.

The effectiveness of forced vibration testing to detect interface fracture within model concrete is examined. Model concrete cylinders containing spherical glass aggregates or voids were cast. Quasi-static load was applied to induce interface fracture between the aggregates and mortar. Resonant frequency was measured from longitudinal standing vibration of the cylinders. Results indicated that the resonant frequency decreased as the amount of voids or load increased. Wave propagation analyses were then used to interpret the experimental results. The calculations indicated that the waves diffracted around the voids during standing vibration, and the diffracted waves decreased the resonant frequency. A similar result was also shown in the cylinders containing interface fractures, since they act as discontinuities along the aggregate-mortar boundaries. Furthermore, the damage conditions within the composite material were also evaluated using these testing and calculation methods. In the load tests, internal cracks were relatively stable in the plain mortar cylinders in the vicinity of maximum load, whereas internal damage of the cylinders containing the glass aggregates developed quickly. The effectiveness of forced vibration testing was demonstrated not only in identifying interface fracture within composite materials, but also in measuring the degree of resulting damage.

For the joint purposes of better informed meso-scale models and for more rational for “materials by design” concepts, we seek to isolate and measure the different mechanisms that lead to high strength and high ductility of steel fiber reinforced ultra-high-performance concrete (UHPC). The work described here jointly applies quantitative x-ray computed tomography(CT) and acoustic emission (AE) techniques to monitor and measure damage progression in split cylinder tests of UHPC. 50-mm diameter specimens of two different fiber types were CT scanned both before and after load testing. From the resulting images, fiber alignment was evaluated to quantify its effect on specimen performance. Results demonstrate the significance of fiber alignment, with best case being between 20 and 30% higher than the worst case. Cumulative AE energy was also affected commensurately. Post-test CT scans of the specimen were used to measure internal energy dissipation due to both matrix cracking and fiber pullout using calibration measurements for each. AE data, processed using an artificial neural network, was also used to classify energy dissipation. CT analysis showed that fiber pullout was the dominant energy dissipation mechanism, however, the sum of internal energy dissipation measured amounted to only 60% of the total energy dissipated by the specimens as measured by the net work of load. AE analysis showed a more balanced distribution of energy dissipation. AE data additionally showed how the dissipation mechanisms shift as damage accumulates.

Adobe is one of the most ancient forms of masonry. Adobe bricks are sundried mixtures of clay, silt, sand and natural fibres locally available joined together using mud mortar. Adobe structures are largely spread in areas of the world prone to earthquakes or involved in military conflicts. Unfortunately, almost no literature concerns the dynamic assessment of soil-based masonry components. From earlier research, it was derived that the mechanical behaviour of adobe in statics fits in the class of quasi brittle materials. Its resemblance with cementitious materials concerns the main failure modes and the constitutive models in compression. This study deals with the experimental characterization of adobe components response in dynamics. It is aimed to study and quantify the rate sensitivity of adobe material from bricks at a wide range of strain rates, from statics up to impact conditions. In particular, the influence of fiber reinforcement in the mixture on the mechanical behaviour of the material has been addressed. Adobe bricks are commonly mixed using organic content locally available in the field, from straw to chopped wood. Fibres are added to prevent shrinkage cracks during the air drying process. In modern materials such as concrete, inclusion of artificial fibres is originally meant to enhance the mechanical performance of the material, benefiting from the selective properties of reinforcement and binder. An experimental campaign was carried out in a collaboration between Delft University of Technology, Dutch Ministry of Defence, TNO and the Joint Research Centre (JRC) of the European Commission. Two types of bricks were tested. They both had the same soil composition in terms of mineralogical family and soil elements proportions but only one was mixed using straw and wood. Cylindrical samples were subjected to compression tests at different rates of loadings in compression: low ( _ 1 = 3 10a#x100000;4 sa#x100000;1), intermediate ( _ 2 = 3 sa#x100000;1) and high ( _ 3 = 120 sa#x100000;1). High strain rate tests were performed using the split Hopkinson bar of the Elsa-HopLab (JRC). For each test, high resolution videos registered the failure process and force-displacement plots were recorded. Elaboration of results revealed clear trends in the dynamic material behaviour. Adobe, as concrete, is sensitive to the loading rate. The rate effects on the main properties of the material in strength and deformation are also analytically and numerically quantified. Rate sensitivity and failure mode are significantly influenced by the inclusion of fibers in the mixture. These effects are quantified, interpreted and compared with modern SFRC. This paper presents the experimental campaign and the obtained results. Moreover, physical interpretations for the observed trends are discussed. Finally, new formulations for the assessment of the dynamic increase factor of the compressive strength of adobe are proposed.
