Effect of Aggregates On Strength Of Concrete Engineering ...

16/03/2012  Aggregates shape and size has a strong influence on properties of concrete. Rough surface textured particles increase the compressive strength of concrete up to 20-30%, instead of using natural gravels that is obtained from river beds. Rough surface have pores which have ability to form bond or create resistance against the applied load.

Effects of Aggregate Properties on Concrete - Size, Grading

Effect of Coarse Aggregate on Strength of Concrete Coarse aggregate makes up about 75% of concrete by volume. Strength of concrete is also affected by the properties of coarse aggregates besides water-cement ratio and other properties. The lower the water to cement ratio, the more the effect of coarse aggregates on the strength of concrete.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

In research on the effects of aggregate content on the behavior of concrete, Ruiz (1966) found that the compressive strength of concrete increases along with an increase in coarse aggregate content, up to a critical volume of aggregate, and then decreases.

The effect of aggregate grading on concrete strength

A. When the w/cm is the same and the mixtures are plastic and workable, considerable changes in grading will not have a large effect on concrete strength. The principal effect of changing the aggregate grading is to change the amount of cementitious material and water needed to make the mixture workable with the desired w/cm.

Effects of Aggregate Properties on Strength of Concrete

Tests were made with 56 combinations of fine and coarse aggregate to study the effects of maximum size and other properties on water requirement and strength of concrete. Results confirm indications of earlier work that, at equal water-cement ratios, smaller sizes of aggregate produce higher concrete strengths than large ones.

Effect of Aggregates on the Properties of Concrete ...

The bond between the cement paste and aggregate is an important factor in the strength of concrete, specially the flexural strength. Bond is partly due to the interlocking of the aggregate and the paste owing to the roughness of the surface of the aggregate particles. Thus rougher the surface as that of a crushed stone, better the bond. Secondly bond is also affected by other
