The effect of maximum size of aggregate on concrete

The effect of maximum size of aggregate on concrete strength. Q. Does the nominal maximum size of the aggregate affect the strength at a given cementitious material content? A. As the nominal maximum size of the aggregate is increased, the amount of water needed for the same workability is reduced.

Effect Of Maximum Size Of Aggregate On Concrete Stre. Effect of Maximum size of Aggregate on Strength of CONCRETE Earlier it was thought that the use of larger size aggregate leads to higher strength.This was due to the fact that the larger the aggregate the lower is the total surface area and, therefore, the lower is the requirement of water for the given workability.

Effects of Aggregate Properties on Concrete Size,

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.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

2014-1-8  There is much controversy concerning the effects of coarse aggregate size on concrete, principally about the effects on fracture energy. Some research (Strange and Bryant 1979, Nallathambi, Karihaloo, and Heaton 1984) has shown that there is an increase in fracture toughness with an increase in aggregate size. However, Gettu and
