摘要: This article describes an experimental study conducted on fresh mortars and concretes made with crushed sand. The aim of this research was to assess the effect aggregate particle shape surface texture as well dust content mortar concrete rheology. programme also addressed impact angular grains chemical admixture performance bleeding. findings showed that use sand induces rheological behaviour differs from observed in natural superplasticisers can improve considerably.
