  The Effect of Aggregate Size on The Strength of Concrete

  Effect of Maximum Aggregate Size on the Strength of Normal and High Strength Concrete. Aggregates form 60% to 75% of concrete volume and thus influence its mechanical properties. The strength of (normal or high-strength) concrete is affected by the maximum size of a well-graded coarse….

  Compressive Strength of Concrete Cube vs Cylinder

  20221111 · Even with the same concrete mix, this will lead to a higher compressive strength in cubes than in cylinders. There is an equation that approximately governs the relationship between the cube and cylinder strengths, which is as follows: Compressive Strength of Cube = 1.25 x (Compressive Strength of Cylinder) As long as the mixture …

  Compressive Strength of Concrete Cylinders

  2017315 · Natural aggregate was replaced with discarded concrete and clay brick aggregates. Addition of recycled clay brick aggregates increases the crushing index. Increase of crushing index exerts a negative impact on mechanical properties. The effects of crushing index on the porosity and permeability can be ignored.

  Cube Test For Compressive Strength Of Concrete

  Crushed concrete shall be processed to reach suitable sizes. The crushing method (mechanical or manual) of concrete to produce coarse aggregate for the production of new concrete is one of the factors that affect the strength of the concrete. It is reported that, coarse aggregate which comply with standards can be produced. However, fine …
