Concrete

Plain concrete, commonly known as concrete, is an intimate mixture of binding material, fine aggregate,
coarse aggregate and water. This can be easily moulded to desired shape and size before it looses
plasticity and hardens. Plain concrete is strong in compression but very weak in tension. The tensile
property is introduced in concrete by inducting different materials and this attempt has given rise to
RCC, RBC, PSC, FRC, cellular concrete and Ferro cement. In this chapter proportioning, mixing,
curing, properties, tests and uses of plain concrete is dealt in detail. The other improved versions of
concrete are explained and their special properties and uses are pointed out.

  • Fibre-Reinforced Concrete (FRC)

    Plain concrete possesses deficiencies like low tensile strength, limited ductility and low resistance to cracking. The cracks develop even before loading.…

  • Prestressed Concrete (PSC)

    Strength of concrete in tension is very low and hence it is ignored in R.C.C. design. Concrete in tension is acting…
