More Than a Nuisance - Construction Demolition

Large-scale, noisy activities such as demolition work or concrete crushing visibly create dust and particles that are noticeable to employers, workers, neighbors and regulators. The activities of mixed CD recyclers may be less visible and might produce dust in overall smaller amounts, but some dust-related hazards must still be kept in mind.

Reinforced Cement Concrete Design Concrete Civil

Reinforced cement concrete Since concrete is a brittle material and is strong in compression. It is weak in tension, so steel is used inside concrete for strengthening and reinforcing the tensile strength of concrete. The steel must have appropriate deformations to provide strong bonds and interlocking of both materials.
