The Mechanical Properties that Nano-SiO2 Affect EPS Light-Aggregate Concrete

EPS light-aggregate concrete is a new kind of light aggregate concrete and is paid more attention by engineers in the field for superior thermal technology performance and prominent economic benefits, in which the Nano-SiO2 can not only fill the lacuna of concrete to improve the performance of concrete but also can improve the mechanics performance and the strength of concrete obviously. The compressive strength and flexural strength of EPS light-aggregate concrete in 3d and 28d were the maximum with 5% Nano-SiO2 in concrete. It is very significant to research the effect of nano-materials on EPS light-aggregate concrete performance, and its application in construction industry will bring great value to practical engineering and social economic benefits to our society.
