The effect of maximum size of aggregate on concrete strength

As the nominal maximum size of the aggregate is increased, the amount of water needed for the same workability is reduced. At the same cementitious material content, strength is therefore greater because the w/cm is lower. But in the high-strength range, over 40 MPa (5800 psi), higher compressive strengths are usually obtained at a given w/cm

The Effect of Aggregate Size on The Strength of Concrete

This study was conducted to determine the effect of concrete strength using coarse aggregate 10mm, 20mm and fine aggregate (sand mining) 3mm, randomly purchased from suppliers. These samples were test using with the mixing ratio of 1: 2: 4 and water cement ratio is set 0.5. The maximum aggregate size requires a low water cement ratio [8]. [1]

Effect of Maximum Aggregate Size on the Bond Strength of

The bond between reinforcements and concrete is the only mechanism that transfers the tensile stresses from concrete to reinforcements. Several factors including chemical adhesion, roughness and reinforcement interface and bar bearing affect the bond strength of reinforcements with concrete. This work was carried out considering another varying factor which is maximum aggregate size.

Effects of Aggregate Properties on Concrete Size, Grading

Effect of Grading. Effects of aggregate properties on Concrete like Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix, density and porosity. It is an important factor and has a maximum influence on workability.

The effect of aggregate size on strength and deformation

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 elongation limit.
