pre-stressed concrete

Pre-stressed concrete is a type of reinforced concrete where internal stresses are intentionally introduced during manufacturing to improve its performance. This is achieved by tensioning steel cables or tendons within the concrete before it fully hardens. Once the concrete sets, the tension is released, placing the concrete in a compressive state, which helps it better withstand tensile (pulling) forces. Pre-stressed concrete allows for longer spans, thinner slabs, and increased durability in structures like bridges, floors, and beams, reducing the need for additional support and enhancing overall strength and longevity.
