The effect of finely ground dune sand on the properties of self-compacting concrete

Abstract

Self-compacting concrete (SCC) is a unique concrete that has been developed over the past thirty years. They have the distinct characteristic of being very fluid. SCC differs from conventional vibrated concrete (CVC) in that it is incredibly fluid and doesn't require vibration. In order to reduce the amount of cement required by the increase in paste volume required to allow the concrete to flow, selfcompacting concretes require a large volume of mineral input. The main goal of this research was to ascertain how replacing cement with crushed dune sand (Sd) affected the SCC's physical and mechanical characteristics. The outcomes show that using crushed dune sand in self-compacting concrete produces interesting outcomes in terms of water absorption and compressive strength.
