Concrete

In this page we are going to talk about concrete: it's definition, it's uses, disvantages and advantages.

Definitions:

1) Concrete: is a manufactured mixture of cement and water, with aggregates of sand and stones, which hardens rapidly by chemical combination to a stonelike, water-and-fire-resisting solid of great compressive but low tensile strength.

2) Reinforced concrete: was developed to add the tensile strength of steel to the compressive strength of mass concrete.

3) Concrete-shell construction: permits the erection of vast vaults and domes with a concrete and steel content so reduced that the thickness is comparatively less than that of an eggshell.

4) Precast-concrete construction: employs bricks, slabs, and supp made under optimal factory conditions to increase waterproofing and solidity, to decrease and cost in erection, and to reduce expansion and contractions.

5) Prestressed concrete: provides bearing members into which reinforcement is set under tension to produce a live force to resist a particular load. Since the member acts like a spring, it can carry a greater load than an unstressed member of the same size.
