Comparison of the influence of silica-rich supplementary cementitious materials on cement mortar composites: Mechanical and microstructural assessment

摘要: The silica-rich supplementary cementitious materials (SCMs) are the key components of mechanical and microstructural properties. use SCMs results in improving properties decreasing environmental burden caused by cement production. In this regard, paper reports a study to compare influence (slag, fly ash, bottom ash) having similar Blaine fineness on mortar composites terms was chosen at using short grinding time due minimize energy consumption cost. Supplementary were ground (~ 3300 cm2/g) then replacing 5 % 20 % with cement, 7-, 28-, 90-day incorporating examined. As result, it observed that compressive strength slag gave control samples (without SCM) according ash will decrease required amount for target properties, thus number CO2 emitted nature also less consumption, cost-effectiveness be ensured shorter strength.
