Q1. What is hydration process during casting of concrete?
Ans. 
Hydration process is the chemical reaction between cement and water which results in the hardening of concrete.
• Hydration process starts as soon as water is added to cement.

• The reaction produces heat and causes the mixture to harden and gain strength.

• The process continues for weeks and even months, resulting in a stronger and more durable concrete.

• The amount of water used in the mixture affects the hydration process and...read more
