Maximum size of coarse aggregate: Maximum size of aggregate affects the workability and strength of concrete. It also influences the water demand for getting a certain workability and fine aggregate content required for achieving a cohesive mix.
Construction aggregate, or simply "aggregate", is a broad egory of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.

use of construction renovation and demolition waste in - - crushing strength of course aggrgate for m20 concret, scrutinize a concrete made of partial replacement of coarse aggregate with construction and demolition waste materials like like compressive strength, workability, flexural strength. .
strength of course aggrgate for mconcrete. Aggregates for Concrete 2.69 Мб. This is especially true for high-strength concrete. The optimum maximum size of coarse aggregate for higher strength depends on factors such as relative strength of the cement paste, cementaggregate bond, and strength of the aggregate particles.
Concrete made with smaller coarse aggregate size have higher strength than concrete made with bigger size of coarse aggregate due to the weak bonds in the later resulting from greater heterogeneity, internal bleeding and

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
Abstract. Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate’s shape,
