Jun 22, 2021 1. Fine Aggregates. The size of the fine aggregates is lesser than 4.75 mm. That is aggregates particles that passed through 4.75 mm. fine aggregates include things such as sand, silt, and clay. Machine-crushed stone crushed gravel might also fall under this category. Typically, fine aggregates are used to improve the workability of a ... Fine aggregates are basically natural sand particles from the land through the mining process, the fine aggregates consist of natural sand or any crushed stone particles that are or smaller. This product is often referred to as 1/4 minus as it refers to the size, or grading, of this particular aggregate.

of crushed pebbles waste as a fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Basic mix was chosen for natural sand to achieve M25 grade concrete. The equivalent mixes were obtained by replacing natural sand by crushed pebbles partially and fully. Sep 03, 2017 Normally sand, gravel, and crushed stone are used as aggregates to make concrete. The aggregate should be well-graded to improve packing efficiency and minimize the amount of cement paste needed. Also, this makes the concrete more workable. Some of the important properties of aggregates are discussed below.
