Reinforced cement concrete is a composite material made of cement, aggregates, water, and reinforcement to enhance its strength and durability.

• Reinforced cement concrete is commonly used in construction to create structures like buildings, bridges, dams, and roads.

• It consists of cement, which acts as a binder, aggregates like sand and gravel, water for hydration, and reinforcement like steel bars or mesh.

• The reinforcem...read more

The nominal concrete proportion varies for different grades of concrete.

• The nominal concrete proportion is the ratio of cement, sand, and aggregate in a concrete mix.

• The proportion is specified by the grade of concrete, which indicates the strength of the concrete.

• Common grades of concrete include M10, M15, M20, M25, etc.

• For example, the nominal concrete proportion for M20 grade is 1:1.5:3, which means 1 part cement, 1

The type of bitumen used for filling cracks in masonry structures varies depending on the specific requirements and conditions.

• The most commonly used bitumen for crack filling in masonry structures is bitumen emulsion.
