Strength Activity Index Test for Pozzolanic Material
Strength Activity Index (SAI) Test (ASTM C311/C311M) Ordinary Portland Cement (OPC) production is highly energy-intensive and contributes significantly to carbon emissions. To reduce cement consumption and improve sustainability, supplementary cementitious materials (SCMs) are incorporated into concrete. Many of these materials exhibit pozzolanic properties, meaning they react with calcium hydroxide [Ca(OH)₂], a by-product of cement hydration, … Read more
