· In construction terms, aggregate refers to granular materials such as sand, gravel, or crushed stone. These components, when combined with cement and water, give birth to what we commonly know as concrete. A key point to remember is that aggregate constitutes about 60-75% of concrete’s total volume.

The waste concrete and glass were crushed, sieved and re-mixed to fulfill the same gradation as the available 0–4 mm crushed limestone aggregate size fraction. The recycled aggregates were substituted for fine aggregate as 0, 15, 30, 45 and 60 % by weight. 28-day mechanical and durability performance of the mixtures were determined.

Coarse aggregate is one of these factors that have a significant influence on SCC. This paper presents the coarse aggregate properties such as maximum size, texture and type of coarse aggregate that have a direct effect on achieving SCC. Three types of coarse aggregate are used, namely crush gravel, uncrushed gravel and crush limestone.

Permeability: Recycled concrete is typically more permeable than other crushed aggregates used in driveways. For this reason, crushed concrete driveways are far more likely to suffer from moisture damage, such as rutting, than the alternative. This increased vulnerability is especially evident in humid areas.
