摘要：

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　invest-gated　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　stag　(GBS)　increases　Autogenous　shrinkage.　Autogenous　shrinkage　is　remarkably　relative　to　SF/FA　or　GBS/FA　remarkable.
