Abstract
To study the effect of new admixtures on the frost resistance of hydraulic concrete and improve its frost resistance and durability in extreme environments,this article adopts research methods such as literature review,experimental research,and numerical analysis to study the effects of different dosages of nano silica on the air content,slump,mechanical properties,and frost resistance of hydraulic concrete.The research results indicate that the optimal mass percent of nano silica in the experiment are 1.0%and 1.2%;The addition of nano silica can reduce the air content and slump of hydraulic concrete;According to the compressive strength test,the addition of nano silica can enhance the compressive strength of hydraulic concrete;According to the frost resistance test,the addition of nano silica can reduce the relative dynamic elastic modulus.关键词
