Hydratation portlandzement
WebArticle principal : Géopolymère. D'un point de vue terminologique, le ciment géopolymère 1 est un liant qui durcit à la température ambiante, à l'instar du ciment Portland. Si un composé géopolymère nécessite l'action de la chaleur, il ne peut être appelé ciment géopolymère, mais plutôt liant géopolymère.

WebThe chemical reaction which takes place between cement and water is known as hydration of cement. This reaction is exothermic in nature, which means heat is released during the reaction, and the evolved heat is called as heat of hydration. Typically, cement produces 89-90cal/gm of heat in 7 days and 90-100cal/gm in 28 days.
