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. Grade of concrete
Ans. 
Grade of concrete refers to the strength of the concrete mix design, typically denoted by a number such as M20 or C30.
• Grade of concrete is determined by the ratio of cement, sand, and aggregates in the mix.

• Higher grade numbers indicate higher strength concrete.

• Common grades include M20, M25, M30, etc. for mix design method and C15, C20, C25, etc. for nominal mix method.

Q2. Compressive strength of concrete
Ans. 
Compressive strength of concrete is the ability of concrete to withstand loads that tend to compress it.
• Compressive strength is measured by testing concrete cubes or cylinders in a laboratory.

• It is important for determining the quality and durability of concrete structures.

• The strength of concrete can vary depending on factors like mix design, curing conditions, and age.

• Typical values for compressive strength range fro...read more

Q4. Method of curing?
Ans. 
Curing is the process of maintaining adequate moisture and temperature for concrete to ensure proper hydration and strength development.
• Curing can be done by methods such as ponding, wet covering, steam curing, and using curing compounds.

• Ponding involves creating a pond of water on the concrete surface to keep it moist.

• Wet covering is done by covering the concrete with wet burlap, sand, or other materials to retain moi...read more
