The Effect of Maximum Coarse Aggregate Size on the Compressive Strength of Concrete Produced in Ghana ... compressive strengths.The results show that the smallest coarse aggregate size gave the highest compressive strength and lowest slump at constant water/cement ratio. A regression analysis also shows that the relationship

Grading limits and maximum aggregate size are specified because these properties affect the amount of aggregate used as well as cement and water requirements, workability, pumpability, and durability of concrete.

Effect of Aggregate Size Distribution on Concrete Compressive Strength 37 Fig: 2 Gradation Curve of Sample having FM-6.0

Differences in concrete strength for a given water- cementing materials ratio may result from: (1) changes in the aggregate size, grading, surface texture, shape,

The Estimation of Compressive Strength of Normal and Recycled Aggregate Concrete 423 2.4. Aggregate ... The influence of aggregate on concrete strength is not generally appreci-ated. Usually, the aggregate strength is not the relevant factor in normal strength concrete ... When performing the change in maximum size of well-graded coarse ...

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

the aggregate size will increase the shrinkage.2 A decrease in the nominal maximum aggregate size from 1-1/2 in. (38 mm) to 3/4 in. (19 mm), for example, will increase concrete

aggregate size on compressive strength of concrete. ... Differences in the mineralogical composition of aggregates affect concrete strength. fc ... Data show that ultimate strength (180 days) of the concretes cast at 50°F were higher than those cast at 100°F.

In concrete dams, river gravel aggregates or commonly crushed stones from quarries are used to make concrete. Crushing of stone requires considerable energy and is expensive. On the other hand, if the maximum size of aggregate is increased, a desirable strength will be reached with lower cement. So ...

• Strong aggregate can not make strong concrete. • When the cement paste of good quality is provided and its bond with the aggregate is satisfactory, then the mechanical properties of the rock will influence the strength of concrete.

The results show that aggregate size is an influencing parameter in regard to concrete spalling, with the degree of spalling ranging from 13 to 33%, respectively. Spalling is more prominent for smaller-size aggregates because of the facture-zone

This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone & brick khoa of aggregates.

PROPERTIES AND MIX DESIGNATIONS ... instance, a large rock size coarse aggregate that is mainly crushed will permit the use of larger size ... Concrete strength increases in an approxim ately constant direct relation to the increase in cem ent content of the concrete. The strength also decreases in a somewhat direct proportion to the

coarse aggregates in high strength concrete Given the critical role that the interfacial transition plays in high-strength concrete, the mechanical properties of coarse aggregate will have a more pronounced effect than they would in conventional-strength concrete.

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 less importance to concrete strength than other aggregate characteristics. Even in the leaner mix, where the larger aggregate gave higher strength, the advantage was inconsequential in ...
