CONCRETE

                


Type of concrete


A).Plain Cement Concrete  (PCC Or CC)
B). Reinforced Cement Concrete (RCC)


A). Plain Cement Concrete


  When a mix of cement material with inert materials such as sand stone blast is made by mixing water in proper proportion, it is called cement concrete.
  Later, it is hardened like a stone by laying it in the form work and place as per the requirement and hardening it like a stone, the weaning is weak and compression is strong.

Use -


 a.Structure PCC
 b.CC Road
 b.Ground floor

 B).Reinforcement Cement Concrete


When steel rods are medicated or rods are placed in plain cement concrete, it is called RCC.
  RCC is more efficient both in tension and compression. It is used everywhere where we have to transfer loads. This is used.

Use-


 a. Buildings
 b. pqc road
 c. RCC Road
 d.  Bridge
  RCC is used almost everywherengredients of cement concrete.

  1.Cement

   Ordinary Portland Cement is used for all general operations. It is easily obtained everywhere. Ordinary cement is prepared from about 65% limestone and 35% clay solution.

2.Fine Aggregate - Sand


We use sand as a fine aggregate, nature's river is extracted from streams and lakes. Grass soil should not be big stones.
  Its size should be between 4 .75 mm - 75 microns.

 3.Coarse Aggregates-ston ballast


   For coarse or large mixing, hard stones such as granite sandstone are made from laterite stone by breaking into ballast shapes.
  Its minimum size is 4.75 my and the maximum size is 200mm.

4. Water


  Water is used to make cement concrete mix. When cement is mixed with water, it has a chemical reaction. It is called water holding action. Cement concrete has an important role of water.
  Water should be clean and its pH value should also be checked as required.
