Closely loaded concrete floor slabs and pavements is usually delicate to cracking and subsequent website traffic-pushed deterioration. As a result, prestressed concrete is frequently used in such buildings as its pre-compression gives the concrete with the chance to resist the crack-inducing tensile stresses generated by in-service loading. This crack resistance also will allow particular person slab sections being produced in much larger pours than for conventionally reinforced concrete, causing broader joint spacings, lessened jointing prices and fewer extended-phrase joint maintenance issues.
Substantial amounts in many cases are transported by truck, poured free of charge under gravity or via a tremie, or pumped by way of a pipe.
