Behavioral studies on sorptivity of the concrete blended with nano silica

Abstract

This study compares the sorptivity of quaternary blended concrete with that of control concrete by utilizing several SCMs, including fly ash (FA), nano silica (NS), and metakaolin (MK). Owing to its compact structural and improved particle refinement, the quaternary blended concrete outperforms the control concrete in terms of water resistance. The increased performance was due to the addition of Supplementary Cementitious Materials (SCMs), which led to a dense and uniform microstructure, and also due to the compact interfacial transition zone. The addition of these SCMs, like flyash, decreases emissions of greenhouse gases and also solves the problem of disposal.
