EFFECTS OF AGGREGATE GRADATION ON THE

Aggregate shape, size and grading can influence concrete workability. The volumes of water and cementations materials are commonly increased to accommodate poorly shaped or poorly graded aggregates. In this work the properties of concrete in fresh and hardened stage using different aggregate sizes and mix design was investigated.

Effects of Aggregate Properties on Concrete AboutCivil.Org

Effect of Size. 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. Effect of Grading. Grading of aggregates depends on the proportions of coarse and fine aggregate.

As a rule of thumb however, the depth should be at least 4 times the dimension of the largest nominal size in the mix for surface course (i.e. 40mm depth for 10mm asphalt concrete); and at least 2.5 times the dimension of the largest aggregate size in the mix for base and binder courses (i.e. 50mm for 20mm asphalt concrete). 8.

EFFECTS OF AGGREGATE TYPES ON THERMAL PROPERTIES

Various physical properties of the concrete ingredients are given in Tables 1 and 2. ASTM standards were followed to determine these properties. The maximum sizes of coarse aggregates for both types were kept 12.5 mm and maintain same gradation curve is shown in Figure-2

sieve, the intermediate (I) is the material passing the 3/8 in. sieve and retained on the #8, and the fine (W) is the aggregate material finer than the #8 sieve and coarser than the #200 sieve. The intermediate size fills the major voids between large particles and reduces the need for the fine material.

Aggregates for Concrete Portland Cement Association

The maximum size of coarse aggregate used in concrete has a direct bearing on the economy of concrete. Usually more water and cement is required for small-size aggregates than for large sizes, due to an increase in total aggregate surface area.

Concrete Aggregates stone, size, rubble, gravel, stones

In proportioning rubble for concrete, the amount of stone is fixed at a certain percentage of the space to be filled. This percentage will vary with the size of the stone that is used, being larger with the larger sizes of stone, and smaller with the smaller sizes.
