Examining the pozzolanicity of supplementary cementitious materials using isothermal calorimetry and thermogravimetric analysis

, 2017
It has recently been proposed that the pozzolanicity of supplementary cementitious materials can be determined by monitoring the heat released when supplementary cementitious materials are mixed with calcium hydroxide at high temperature and high pH.
