In the present work morphology of natural fibers was correlated with their mechanical properties via image analysis. Jute, sisal, curaua, coir and piassava were tested under direct tension in a universal testing machine cross-sectional areas calculated using images obtained scanning electron microscopy. For jute fiber tests performed for several gage lengths order to investigate its influence on tensile strength compute compliance. curaua amount fiber-cells, size cell walls real area...
In this research project the behaviour of strain-hardening cement-based composites (SHCC) subjected to low and high strain rates was studied. Uniaxial tension tests on dumbbell-shaped SHCC specimens were performed at ranging from 10-5s-1 50s-1. For 10-2s-1 below, yielded a moderate increase in tensile strength simultaneous decrease capacity with increasing rate. When tested for higher 10 50s-1 considerable measured. Microscopic investigation fracture surfaces showed that almost no fibre...
Abstract Textile-reinforced concrete (TRC) has gained a lot of attraction in recent years. Adequate bond between the phases this system allows to transfer high loadings, thus enabling performance. The terminus textile reinforcement, however, comprises many different types fabrics, which differ their chemical composition, geometry, surface properties etc., and exhibit substantially properties. In course RILEM’s Technical Committee 292 work on TRC it was found that comprehensive understanding...
