Effect of Super Mineral Powder on Autogenous Shrinkage of Cement Paste

The paper investigates the effect of super mineral powder on Autogenous shrinkage of cement paste. Two multiplex Admixture is mixed into cement paste respectively.Effect of super mineral powder is investgated by estimating the samples of different SF/FA (the ratio of mass of SF to FA) and GBS/FA(the ratio of mass of GBS to FA).It is found that fly Ash(FA) reduce Autogenous shrinkage,silica fume(SF) and ground granulated blast furnace slag(GBS) increases Autogenous shrinkage.Autogenous shrinkage is remarkably rela- tive to SF/FA or GBS/FA remarkable.
