02/05/2017 · Variation in the size of Aggregates changes the water demand, cement content, microcracking (strength) in concrete. It also effects pumpability, and durability of concrete. When the particles are of uniform size the spacing is the greatest, but when a range of sizes is used the void spaces are filled and the paste requirement is lowered.

of Coarse Aggregates: The size of the coarse aggregate depends on the use of the concrete is to be poured. For largescale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size will be used.

Over the years many different aggregate proportioning techniques have been used to create a concrete mixture. Aggregate can be proportioned by volume, minimum voids, and gradation. Furthermore, a well designed and economical mixture will effectively use the aggregate to reduce the amount of paste in a mixture, but still achieve the required workability, which is called optimized graded concrete.

Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.

In designing concrete structures, normally maximum aggregate sizes are adopted with ranges from 10mm to 20mm. Does an increase of maximum aggregate size benefit the structures? To answer this question, let's consider an example of a cube. The surface area to volume ratio of a cube is 6/b where b is the length of the cube.
