| Popis: | Newly the High Strength Concrete (HSC) and High-Performance Concrete (HPC) have been widely used in building projects. HSC and HPC is not just a simple mixture of cement, water and aggregates. HSC and HPC lead to achieving the maximum compressive strength of 120 to 150 MPa. At such level of intensity the coarse aggregate becomes the weakest link in concrete. The strength and durability of concrete was improved by way of removing the coarse aggregate and employing the mineral admixtures and steel fibers is the philosophy to develop Reactive Powder Concrete (RPC). In this paper, the development of incorporated GGBS based Reactive Powder Concrete (RPC) with several mineral admixtures and micro steel fiber was studied and discussed. Four different mineral admixtures were added in RPC, such as fly ash, ground granulated blast furnace slag (GGBS), Quartz powder and silica fumes; also the micro steel fibers were used. The specimens were cast for finding mechanical and durability of RPC was studied and discussed. |
