Instantaneous activation energy of alkali activated materials
RILEM Technical Letters, 2019 Alkali activated materials (AAM) are generally cured at high temperatures to compensate for the low reaction rate. Higher temperature accelerates the reaction of AAM as in cement-based materials and this effect is generally predicted using Arrhenius ...
