Q1. Slump test procedure
Ans. 
The slump test is a method to measure the workability of fresh concrete.
• A slump cone is filled with fresh concrete and compacted in three layers

• The cone is then lifted and the amount of slump is measured

• The slump value indicates the consistency of the concrete

• The test is performed in accordance with ASTM C143 or EN 12350-2 standards

Q2. Types of concrete, materials used for concrete
Ans. 
Concrete is a composite material made up of cement, water, and aggregates.
• Types of concrete include plain, reinforced, pre-stressed, and lightweight.

• Materials used for concrete include cement, water, aggregates (sand, gravel, crushed stone), and admixtures (chemicals added to improve properties).

• Different types of aggregates can be used to achieve different properties, such as strength, durability, and workability.

Q2. Mix ratios for grade of concrete
Ans. 
Mix ratios for grade of concrete
• Mix ratios for concrete vary depending on the grade of concrete required

• For example, for M20 grade concrete, the mix ratio would be 1:1.5:3 (cement:sand:aggregate)

• Higher grade concrete requires a higher proportion of cement in the mix

• The mix ratio should be carefully calculated to ensure the desired strength and durability of the concrete
