Tests done on reinforcement include tensile strength, bending test, elongation test, and rebend test.

• Tensile strength test measures the maximum stress a reinforcement bar can withstand before breaking.

• Bending test checks the ability of reinforcement to bend without breaking.

• Elongation test measures the ability of reinforcement to stretch without breaking.

• Rebend test checks the ability of reinforcement to bend and then ...read more

Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.

• 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 being used and the specific application.

• For example, a water cement ratio of 0.45 i...read more

Curing is a process of maintaining moisture in concrete to ensure proper hydration and strength development.
