2. What is the difference between RCC and PCC concrete? What are the advantages of PSC over RCC? Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading. In pre-tensioning the reinforcement, in the form of tendons or cables, is stretched (put into tension) across the concrete formwork before the concrete is placed. Generally, concrete NU girders are deeper than steel girders over the same span. Prestressed concrete is more predictable than RCC. 4 Whats the difference between reinforced concrete? The main function of the reinforcement is to strengthen concrete when it undergoes tensile stress. Prestressed concrete sections are thinner and lighter than RCC sections, since high strength concrete and steel are used prestressed concrete.

Prestressed concrete is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. . Is prestressed concrete stronger than reinforced concrete? The strength gain in PPC is less, and it is also not suitable for high performance concrete and quick concrete setting, whereas PSC brings the ultimate strength and excellent finish, reducing the risk of shrinkage cracks and cracking. The break through in prestressed concrete applications enables reduced section sizes and reduction in self-weight. Some of which are explained below : The cement concrete in which reinforcement is provided for taking tensile or excessive compressive and shear stresses is called Reinforced Cement Concrete. 2) Pre stressed concrete allows for a longer span. Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces. Prestressing process involves application of an initial compressive pre-stress on a structure to minimize or eliminate the internal tensile forces this will help to control or Stiffer Members. By casting the wet cement around reinforcing steel bars the resultant composite material has much more strength under tension while still keeping the properties that make PCC so effective. Therefore, PSC holds the advantage.24 September 2019. tgm hd``dwinf toe`m fivms tgm u`ticotm tmnsi`m strmnftg dh stmm` wirms usma hdr, O strona dr boe`m is coam dh o euna`m dh wirms spun tdfmtgmr.
