| Abstract | ||
| The main purpose of this research is to study the strength of the RPC incorporating local powders (reactive silica sand powder) and compare it with RPC incorporating condensed silica fume. Original RPC- in form of superplasticized cement mixture with powder (reactive silica sand or silica fume ), steel fiber ,and fine sand (<600 mµ)- was studied in comparison with modified reactive powder concrete (MRPC) where a natural aggregate (max size 8mm)was used to replace the fine sand of the cementitious binder. In the present research work compressive strength, (incorporating local reactive silica sand powder) of reactive powder concrete and modified reactive powder concrete were studied. High 28-day compressive strengths (101-115 MPa) were gained when using local powders. | ||
