How Coarse Aggregate Affects Mix Design of …

Proper grading of coarse aggregate can minimize the possibility of segregation, especially for higher workability and improves the compatibility of concrete. The coarse aggregate grading limits are given in ASTM C33/ C33M and IS 383 – 1970 - table 2, Clause 4.1 and 4.2 for single size aggregate as well as graded aggregate.

Role of Aggregate in Concrete Countertop Mix Designs

Aggregate gradation, whether in a mortar concrete or a traditional concrete mix, involves tradeoffs between strength and workability and is always a delicate balance. Understanding the implications of aggregate gradation is especially important when creating a from-scratch mix and will ultimately help you produce a better precast concrete countertop.

Importance of aggregate grading

Importance of aggregate grading. Ideally coarse and fine aggregate should be graded in such a way as to minimise the voidage. After compaction the volume of the cement paste must be more than the voidage between particles. Underfilling will result in entrapped air and an unworkable mix.
