摘要
Abstract
In order to study the nano-SiO2 of high-performance concrete workability and the mechanics properties of nano-SiO2,adding the nano-SiO2 to the high performance concrete,through the contrast test of basic concrete,fly ash concrete,nano-SiO2,fly ash concrete,so study the effect of nano-SiO2 of high-performance concrete slump,compressive strength,tensile strength of splitting.The results show that： adding to the nano-SiO2 to the concrete materials which have mproved the compressive strength,tensile strength,fracturing pressure and workability;N ano-SiO2 and mineral admixtures has superimposition effect of the concrete early strength especially 7 d strength are obvious drop brittle toughening role.关键词
