Portland cement concrete Portland cement concrete is a construction material made by combining Portland cement, water, sand, and coarse aggregate. The cement binds the ingredients together as it hardens into a strong, durable surface.
Most sidewalks, driveways, curbs, and pedestrian ramps in NYC are built with Portland cement concrete because it provides long-term strength and weather resistance. The final performance depends on the quality of the mix, proper placement, and adequate curing. Different mix designs may be specified depending on traffic loads and project requirements.
