The Effect of Aggregate Properties on Concrete

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.

Two bricks were used per layer, with a 90-degree orientation shift between layers, and mortar layers of 12 mm. Standard material testing indicated an average compressive strength of 10 MPa and 0.9–1.2 MPa for the bricks and mortar, respectively. The upper strength value for the mortar indicates fully carbonated lime mortar specimens.

Concrete compressive strength of 100MPa is achievable when utilized maximum aggregate size ranges from 10 to 20 mm.

Compressive Strength an overview | ScienceDirect Topics

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

What is the effect of coarse aggregate size in compressive

When we design mix the concrete, its target strength is much less than the compressive strength of the aggregates used in the formation. It can also be clearly seen in the mix design procedure that greater the maximum size of coarse aggregate used, less is the cement required to achieve the target strength.

Effect of Aggregate Size on Strength| Concrete

Q.: How much stronger is a floor made with 1/2-inch aggregate than one with 3/4-inch aggregate if all other ingredients remain the same? A.: If the quantities of coarse aggregate, fine aggregate, cement and water are the same for both mixes, the mix with l l/2-inch aggregate will have greater slump and will probably bleed more.
