Q1. What's slump test
Ans. 
Slump test is a concrete test to measure the consistency and workability of freshly mixed concrete.
• It is performed by filling a cone-shaped mold with concrete, then removing the mold and measuring how much the concrete slumps or settles.

• The amount of slump indicates the water content and workability of the concrete.

• Different types of slumps (true slump, shear slump, collapse slump) can provide insights into the quality...read more

Q1. What is the weight of green concrete?
Ans. 
The weight of green concrete varies depending on the mix design and components used.
• The weight of green concrete typically ranges from 140 to 150 pounds per cubic foot.

• Factors such as the type and amount of aggregates, cement, water, and admixtures used can affect the weight.

• Lightweight concrete can have a lower weight, while high-density concrete can be heavier.

• The weight of green concrete is important for structural

Q2. What is the formula of tensile Strength of concrete?
Ans. 
The formula for tensile strength of concrete is based on the cross-sectional area and maximum load applied.
• Tensile Strength = Maximum Load / Cross-sectional Area

• The units for tensile strength are typically in MPa (megapascals)

• Tensile strength is an important property of concrete for determining its ability to resist tension forces

• For example, if a concrete specimen with a cross-sectional area of 100 square millimeters ...read more

Q3. What is the water cement ratio of concrete?
Ans. 
The water cement ratio of concrete refers to the ratio of the weight of water to the weight of cement used in a concrete mix.
• The water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The ideal water cement ratio varies depending on the type of concrete mix and its intended use.

• For example, a typical water ce...read more
