摘要：

Functionally modified fly ash zeolite-geopolymeric material was developed as cooling coatings for structural application. The tailored precursor of cool coating materials was obtained through modified grain behavior of zeolite with variable pour morphology and mechanical activation of fly ash followed by geopolymerization with alkaline activator. The modified zeolite was found to possess unique heat management properties through disorderly connected pores. The solar temperature profile showed a temperature variance of 4-6 degrees C for solar radiation. The samples showed a high solar reflective index (SRI) due to absorbance and less heat retention followed by cooling behavior in the sunshine.
