The present research work investigates the utilization of metakaolin as a mineral admixture in improving the properties of concrete mixes, containing varying percentages of recycled coarse aggregates (RCA). For this, fifteen concrete mixes have been designed by substituting natural coarse aggreg...detailed
The effects of simultaneous addition of limestone and metakaolin with different mass ratio on the hydration of Portland cement are investigated by a multi-method approach. The results indicate that the strengths of Portland cement mortars are depended on the mass ratio of metakaolin to limestone...detailed
Pervious concrete has been studied widely considering its environmental benefits. Owing to its porous nature, it reduces the runoff quantity recharging the groundwater and as well reduces the effect of urban heat island. Previous studies have been focused on characterizing and understanding stru...detailed
The influences of rice husk ash (RHA) on the reaction kinetics, mechanical property, and microstructure of metakaolin-based geopolymer (MG) were investigated. Geopolymer pastes containing different contents of RHA were prepared by sodium silicate activation. Analysis results show that both metak...detailed
