How does Aggregate Properties Affect Concrete? - The ...

17/06/2014  Coarse aggregates have properties such as size, shape, moisture contents, specific gravity, density etc. which affects concrete strength and durability in many ways. These effect of aggregate properties on concrete are discussed in detail. Concrete is a mixture of cementitious material, aggregate and water. Aggregate is commonly considered inert filler, which accounts for 60

The Effect of Aggregate Properties on Concrete

18/05/2018  Aggregates form about 75% of concrete by volume. In terms of weight it may form up to 85% of concrete. Therefore attention has to be given on the selection and quality control of aggregates. Although aggregates are inert in nature it has a strong effect on the concrete's thermal and elastic properties. And although it only acts as a filler, it affects the dimensional stability of concrete.

Effect of Aggregate Quality on the Properties of Concrete

aggregate significantly affects the properties of concrete since it constitutes about 70% of the volume of concrete. Several criteria, such as ASTM C 33 [1999], were developed as guidelines for utilizing high-quality coarse aggregates to produce durable concrete. However, with dwindling sources of high-quality coarse aggregates, the validity of these criteria is often questioned. This concern ...

ABSTRACT: This paper investigated the effect of aggregate proportion on concrete properties both at the fresh state and in the hardened state. Aggregate proportion as used in this research refers to the ratio of fine aggregate to coarse aggregate in a concrete mix. Five concrete mixtures with different aggregate proportion ranging from 0.3-0.5 were batched to check the effect of aggregate ...

In contrast to rounded aggregates, angular aggregates have high angularity numbers and higher specific surface area available for proper bonding between cement paste and aggregates along with better interlocking properties which makes them the most recommended shape for aggregates in the manufacture of concrete. But, an increase in such angularity number decreases the workability of the concrete.

Effects of shape and size of aggregates in concrete

How does the shape and size of coarse aggregates affect the properties of concrete? A. Aggregate shape and surface texture influence the properties of freshly mixed concrete more than the properties of hardened concrete. Rough-textured, angular, and elongated particles require more water to produce workable concrete than smooth, rounded compact aggregate. Consequently, the cement content
