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. What is workability of concrete ?
Ans. 
Workability of concrete refers to its ease of mixing, placing, and compacting.
• Workability is an important property of concrete as it affects its strength, durability, and overall performance.

• It is influenced by factors such as water content, aggregate size and shape, cement content, and admixtures.

• Concrete with good workability is easier to handle, transport, and finish.

• Workability can be measured using tests like slum...read more

Q1. What types of admixture ?
Ans. 
Admixtures are substances added to concrete to enhance its properties or performance.
• Admixtures can be classified into different types based on their purpose, such as water-reducing admixtures, air-entraining admixtures, accelerating admixtures, retarding admixtures, and superplasticizers.

• Water-reducing admixtures reduce the amount of water needed in the concrete mix, improving its workability and strength.

• Air-entraini...read more

Q3. Weight of 10 mm diameter a bar ?
Ans. 
The weight of a 10 mm diameter bar depends on the material it is made of.
• The weight can be calculated using the formula: weight = volume × density

• The volume of a cylindrical bar can be calculated using the formula: volume = π × (diameter/2)^2 × length

• The density of the material can be obtained from reference tables or material specifications

• For example, the weight of a 10 mm diameter steel bar with a length of 1 meter ...read more
