Grading of Aggregates and Grading Limits – theconstructor

Grading of aggregates is an important factor for concrete mix design. These affect the concrete strength as well as durability. Proper grading is important for concrete construction. Following tables provides details for grading limits of aggregates.

A Simple Guide to Aggregate Gradation & Sieve Analysis

Uniformly graded aggregate. All the particle sizes are roughly the same size, which is the case in many clear stone products (e.g. #57 stone). The high void content leads to low stability and makes it difficult to compact. Water drains more easily through uniformly graded aggregates.

The Effect of Aggregate Properties on Concrete

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
