WHAT IS AGGREGATE HOW TO FIND OUT GOOD AGGREGATE

AGGREGATE                                                                  Aggregate gate are inert material which are mixed with binding material such as cement or lime for manufacturing of mortar or concrete

       Aggregate are used as filler in mortar and concrete and also to reduce their cost

Good qualities of an ideal aggregate

    It should be hard, strong, and durable

    It should be dense, clear and free from any coating

    It should not be contains flaky(angular) and elongated pieces

    It should not contain any material liable to attack steel reinforcement in case of reinforcement concrete

Classification of aggregate  

   1#On the basis of geological orgien

          Artificial aggregate

          Natural aggregate

   2#On the basis of grain size

          Coarse aggregate

          Fine aggregate

   3#On the basis of shape

          Round aggregate 

          Irregular aggregate

          Angular aggregate

          Flaky aggregate

   4#On the basis of unit weight

          Light weight concrete

          Normal Weight

          Heavy weight

   5#Quality test of aggregate

           Crushing test of aggregate test

           Impact value aggregate test

           Abrasion value test
