...N.R. Vadiraj Rao; M. Manjunatha; M.C. Nataraja Purpose The present investigation uses recycled aggregates (RA), fly ash (FA) and manufactured sand (MS) to examine the bond performance of concrete. Various mixes (M1, M2, M3, M4 and M5) were developed by incorporating hybrid fibres with FA and MS...

... to increased water requirement of concrete. This seriously limits its applicability and as a result it reduces the usage of RCA in structural members. In the present study, the impact of hybrid fibres on cracking behaviour of RCA concrete beams along with the inclusion of reinforcing steel bars under two-point...

... and cylinders with 300 mm length and 150 mm diameter with hybrid fibres (0.15% polypropylene fibres + 0.35% steel fibres) along with fly ash. The specimens were exposed to elevated temperatures between 400 to 700°C with 100°C intervals for 2 h of duration and the post-fire exposed samples were further subjected...

...Sachin B.P.; N. Suresh Purpose The present experimental investigation attempts to study the behaviour of hybrid fibre-reinforced self-compacting concrete (HFSCC) subjected to elevated temperature. The purpose of this study is to find out the performance of hybrid fibres of 0.5 per cent by volume...
