Q1. What is the standard &nominal size of brick in India. What are admixtures in concrete.
Ans. 
The standard size of brick in India is 190mm x 90mm x 90mm. Admixtures are chemicals added to concrete to enhance its properties.
• The nominal size of brick in India is 200mm x 100mm x 100mm, but the standard size is 190mm x 90mm x 90mm.

• Admixtures are added to concrete to improve its workability, strength, durability, and other properties.

• Examples of admixtures include water reducers, accelerators, retarders, air-entrain

Q2. How water ratio cement associated with strength of concrete.
Ans. 
Water-cement ratio affects the strength of concrete.
• Higher water-cement ratio leads to lower strength of concrete.

• Lower water-cement ratio leads to higher strength of concrete.

• Ideal water-cement ratio is 0.45 for maximum strength.

• Excess water can cause shrinkage and cracking of concrete.

• Example: A concrete mix with water-cement ratio of 0.5 will have lower strength than a mix with ratio of 0.4.

Q1. How many Law of thermodynamics do you know?
Ans. 
There are three laws of thermodynamics.
• There are three laws of thermodynamics: the zeroth law, the first law, and the second law.

• The zeroth law states that if two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other.

• The first law states that energy cannot be created or destroyed, only transferred or converted.

• The second law states that the entropy of an isolated system

Q4. Can you tell me about grain boundaries?
Ans. 
Grain boundaries are interfaces between grains in a polycrystalline material, affecting material properties.
• Grain boundaries are regions where the crystal structure changes orientation.

• They can affect material properties such as strength, conductivity, and corrosion resistance.

• Grain boundaries can be classified as low-angle or high-angle boundaries based on the misorientation angle.

• Examples include the use of grain bou...read more
