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

Q3. Why used send in concrete mixer
Ans. 
Water is added to concrete mixer to make the mixture more workable and to achieve the desired consistency.
• Water is added to hydrate the cement and activate the chemical reaction that causes it to harden

• The amount of water added affects the strength and durability of the concrete

• Too much water can weaken the concrete and cause cracking

• The water should be added gradually and mixed thoroughly to ensure even distribution

Q1. Tell me about slump test
Ans. 
Slump test is a measure of the consistency of fresh concrete.
• It is used to determine the workability of concrete.

• A slump cone is filled with fresh concrete and then lifted vertically.

• The amount of slump or settlement of the concrete is measured.

• The test helps to ensure that the concrete is of the right consistency for the job.

• The slump test is widely used in construction projects.
