Fly ash is a byproduct of coal combustion and is used in cement to improve workability, reduce permeability, and increase durability.

• Fly ash is a fine powder that is added to cement to improve its properties.

• It is a byproduct of coal combustion and is collected from power plants.

• Fly ash improves workability by reducing water demand and increasing pumpability.

• It reduces permeability and increases durability by filling v...read more

The curing period of concrete is the time required for it to gain sufficient strength and durability.

• Curing is a crucial process in concrete construction that involves maintaining moisture and temperature conditions to allow proper hydration of cement.

• The duration of the curing period depends on factors like the type of cement used, ambient conditions, and the desired strength of the concrete.

• Generally, the curing peri...read more

Compression zone is located at the bottom of a simply supported beam and at the top of a cantilever beam. Tension zone is located at the top of a simply supported beam and at the bottom of a cantilever beam.

• In a simply supported beam, the compression zone is located at the bottom because the beam is supported at its ends, causing the bottom fibers to be compressed.

• In a cantilever beam, the compression zone is located a...read more

PCC stands for Plain Cement Concrete and RCC stands for Reinforced Cement Concrete. The density of steel is around 7850 kg/m³ and the density of cement is around 1440 kg/m³.

• PCC is a type of concrete made with cement, sand, and coarse aggregates.

• RCC is a type of concrete made with cement, sand, coarse aggregates, and steel reinforcement.

• The unit of PCC and RCC refers to the measurement of volume or quantity used in cons...read more
