1.2.2 General classification of aggregate
Aggregates are divided into two categories from the consideration of size- (1) Fine aggregate and (2) Coarse aggregate. The size of aggregate bigger than 4.75 mm is considered as coarse aggregate and aggregate whose size is 4.75 mm and less is considered as fine aggregate
1.3 Project objectives
Prior to using any new material in construction, it is essential to know its behavior and various properties that are needed in design. In the present investigation, the production of concrete using conventional materials and some

Coarse aggregate is that aggregate whose particles completely pass through 7.5 cm mesh sieve and which are entirely retained on 4.75 mm sieve. Aggregate having particles greater than 7.5 cm is
The materials used as coarse aggregate can be of various types such as
2. Crushed rock such as granite, basalt, limestone, sandstone etc.
commonly known as stone chips.
3. Broken brick (khoa) etc.
Bricks used for aggregate are further classified into following categories:
2. Second class brick

3. Picked brick
4. Over burnt or jhama brick etc.
