Classification, Physical and mechanical properties, soundness, alkali-aggregate reaction, thermal properties of aggregate
Aggregates are the important constituents of the concrete which give body to the concrete andalso reduce shrinkage. Aggregates occupy 70 to 80 % of total volume of concrete. So, we can say that one should know definitely about the aggregates in depth to study more about concrete.
Classification of Aggregates as per Shape and Size: Aggregates are classified based on so many considerations, but here we are going to discuss about their shape and size classifications in detail.
Classification of Aggregates Based on Shape:
We know that aggregate is derived from naturally occurring rocks by blasting or crushing etc.,so, it is difficult to attain required shape of aggregate. But, the shape of aggregate will affect the workability of concrete. So, we should take care about the shape of aggregate. This care is not only applicable to parent rock but also to the crushing machine used. Aggregates are classified according to shape into the following types
Aggregates are classified according to shape into the following types Rounded aggregates
Irregular or partly rounded aggregates
Angular aggregates
Flaky aggregates
Elongated aggregates
Flaky and elongated aggregates
