These days, the world is facing a global environmental and sustainability problem due to increasing generation of large amounts waste through construction demolition work, which causes serious for environment. Therefore, this research was conducted get rid disposal problems, including old glass concrete, were used as recycled fine aggregates. Seven different mixtures prepared. The first mixture...

Reactive powder concrete (RPC) is a special type of with microstructure optimised by precise gradation all particles in the mix to yield maximum density. Therefore, RPC exhibits ultrahigh strength and durability. High-strength reinforcement has both high good plastic deformation properties, so combination high-strength can fully exploit their respective advantages. At present, there little rese...

The performance of reactive powder concrete (RPC) is much higher than that ordinary concrete, and the engineering application gradually increasing. bond failure process slip between RPC reinforcement will show new characteristics. It necessary to study behavior steel bar. direct drawing test was carried out on 36 bonding specimens in order bar concrete. research shows cohesive force consists th...
