Q1. Concrete grades and meaning?
Ans. 
Concrete grades are classifications that indicate the strength of the concrete mix used in construction.
• Concrete grades are denoted by the letter 'M' followed by a number, such as M20, M30, etc.

• The number after 'M' represents the compressive strength of concrete in N/mm^2 after 28 days of curing.

• Higher grade numbers indicate higher strength concrete, suitable for different types of construction projects.

• For example, M2...read more

Q2. Concrete strength gain after 7 days?
Ans. 
Concrete strength typically reaches about 70-80% of its final strength after 7 days.
• Concrete strength gain after 7 days is usually around 70-80% of its final strength

• Factors such as mix design, curing conditions, and type of cement can affect the rate of strength gain

• For example, high early strength concrete may reach higher percentages of its final strength after 7 days compared to normal concrete

Q6. Transportation of concrete?
Ans. 
Transportation of concrete involves mixing, loading, and delivering the concrete to the construction site.
• Concrete is mixed at a batching plant using cement, sand, gravel, and water.

• The mixed concrete is then loaded into transit mixers or concrete trucks for transportation.

• Transit mixers rotate to prevent the concrete from setting during transportation.

• Concrete pumps can also be used to transport concrete to hard-to-re

Q7. Why we use Admixture in ready mixed concrete?
Ans. 
Admixtures are used in ready mixed concrete to improve workability, durability, and strength.
• Admixtures help in reducing water content while maintaining workability.

• They enhance the durability of concrete by reducing permeability and increasing resistance to chemicals.

• Admixtures can also accelerate or retard the setting time of concrete.

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