The Analysis of Nano SiO2 Impacting on the Frost Resistance of EPS Lightweight Concrete

Styrofoam (EPS) lightweight concrete, a new type of lightweight aggregate concrete, whose superior thermal performance and remarkable economic benefit earns more and more attention from the engineering. Adding nanoSiO2 into it can improve the frost resistance of EPS lightweight concrete, so that it can improve the microstructure and mechanical properties of concrete. The research on the nanomaterials has the vital significance to the frost resistance of EPS lightweight concrete. The wide application of this technology will greatly promote the development of construction industry, and has very important engineering practical value and social economic benefits.
