Effects of Aggregate Properties on Concrete

Variation in the size of Aggregates changes the water demand, cement content, micro-cracking (strength) in concrete. It also effects pumpability, and durability of concrete. Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of ...

Effects of Coarse Aggregate Size on the Compressive …

This study investigates the effect of aggregate size on the compressive strength of concrete. Two nominal mixes, that is, 1:2:4 and 1:3:6 were used in the study. Concrete cubes were produced with 6, 10, 12.5, 20 and 25 mm aggregates for the two nominal mixes and they were subjected to compressive strength test after curing for 7, 21, 28 and 56 days.

Similarly, higher flexural strength is obtained at a given w/cm with smaller nominal maximum size aggregate. Data from compression tests of concrete containing very large aggregates, 100 mm (4 in.) and over, are conflicting because of limitations in the size of the test specimens and testing machines.

Effect of Aggregate Size on Strength| Concrete …

 · If, however, the two mixes are designed for the same slump and workability, and with the same cement content, the mix with l/2-inch aggregate is likely to be somewhat stronger, because its water-cement ratio will be lower. However this increase in strength may not be significant because of other factors that affect strength.

How does Aggregate Properties Affect Concrete?

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 to […]

The Role Of Aggregate On Concrete Strength

Excessive aggregate size will also make the concrete less workable. Chunks of aggregate may even end up protruding from the surface. As a general rule, your maximum aggregate size should never be greater than 1/3 the depth of the slab.
