What is Accelerating admixture & why? ঢালাই দ্রুত জমাট বাধা!

Accelerating admixtures are chemical substances added to concrete, mortar, or grout to speed up the hardening process. They do this by increasing the rate at which cement hydrates, which reduces the time it takes for the concrete to set.  How they work Accelerating admixtures react with the tri-calcium silicate in cement  They increase the rate of chemical reactions between water and the clinker materials in cement  They can accelerate both the setting and hardening of concrete
