Added an answer on July 22, 2020 at 1:32 pm. The tensile strength of the concrete is severely affected by increasing the size of the aggregate. On increasing the maximum grain size to 120–180 mm, the reduction in tensile strength is 30–50% as compared with concretes with maximum aggregate size 20 mm. There is also a reduction in the ...

The typical unit weight (or density) of a 10mm coarse aggregate/ crushed stone/ gravel/ coarse sand is range between 1525 kg/m3 and 1575 kg/m3. This means that the weight of 1 cubic meter of 10mm course aggregate is about 1525 kg to 1575 kg (or 1.525 to 1.575 MT). 10mm … See more

The usual range of aggregate used in construction is between 9.5 mm and 37.5 mm in diameter, with the most common size being 20 mm. Coarse-grained aggregates are particles larger than 9.5 mm. A larger size, 40 mm, is more commonly used in bulk concrete. The size distribution of fine to coarse-grained aggregates plays an …

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.

Grading Limits for Fine Aggregates. (Based on Clause 4.3 of IS: 383 - 1970) Grading of aggregates are determination of particle size distribution of aggregates. 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.
