For the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate. In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement.
Aggregate up to 1.5 inch maximum size, concrete compressive strength increases. Aggregate above 1.5 in Aggregate above 1.5 in maximum size the gain in strength due to the reduced water requirement is offset by the detrimental effect of lower
Test results obtained on the effect of specimen size and aggregate size on concrete compressive strength and modulus of elasticity are presented. The concrete was prepared using 4.75, 9.5, 19.0, 37.5, and 75-mm nominal maximum size aggregate. Over 600 cylinders were cast and tested for concrete ...

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler, it is a necessary component that defines the concrete…

The properties of concrete were studied when the proportions of 37.5 and 19.5 mm stone in the coarse aggregate were varied. With the cement content of 160 kg/m 3 and the ratio of water/cement (w/c) greater than 0.9, the compressive strength is maximum at 25 percent by weight (w/o) of 37.5 mm stone. Conversely, for the cement content of 350 kg/m 3 and w/c ratios of less than 0.50, maximum ...
The effects of the maximum void size and aggregate shape and roughness on the flexural strength of high strength mortar were investigated. Substantial reductions in the maximum void size and air content of quartz aggregate mortars resulted in flexural strength increases.
Influence of the maximum aggregate size on compressive strength are reported. A wide range of cement content and aggregate sizes were used In the large test specimens, used to minimize the effect of specimen size. Effect of Maximum Size Aggregate on Compressive Strength of Mass Concrete Elmo C. Higginson, George B. Wallace, and Elwood L. Ore I T HAS LONG BEEN ESTABLISHED THAT concrete ...
The effects of maximum size coarse aggregate on the relationship between accelerated strength and 14-day normally cured strength of normal and superplasticized concrete have been investigated. The results obtained show that differences among maximum size coarse aggregates are greater in nomral concrete than in superplasticized concrete in strength …

quite suitable for a dense-graded asphaltic concrete of 1 in. maximum size. Vallerga (14) believes that "Brittleness (or inflexibility) of asphaltic pavingmixtures is a function of asphalt content, aggregate grading, and, in particular, the final condi-
It appears that optimum maximum size, so far as strength is concerned, will vary for different aggregates, different cement factors, different test ages and probably other conditions. 4. A realistic appraisal of the recent data for several different aggregates must lead to the conclusion that size of aggregate, within a reasonable range, is of ...
Research is described supplementing earlier work which indicated a lack of improvement in concrete strength resulting from increased maximum size of aggregate.
Effect of the maximum size of coarse aggregate on the main parameters of concrete . Authors; Authors and affiliations; A. M. Ibragimov; The Latest in the Construction of Arch Dams. Conclusions. 1.

First of all, when making high-strength concrete the strength is seen to decrease with increasing maximum size. This is not a really a problem with normal concrete, however. The most important issue is with the need for the concrete to uniformly fill the mold as it is placed without segregating. For this to happen, the largest aggregate ...
