25/06/2014 Importance in terms of Workability. A workable concrete can be achieved by adding more water, but as we know the more water present in concrete the poor strength it gives. The most efficient way to achieve workable of concrete is by adopting a good gradation of aggregate. Also aggregate comprises 85% of the volume of concrete.

Aggregates having a smooth grading curve and neither a deficiency nor excess of any one particle size will generally produce mixtures with fewer voids between particles. Since cement costs more than aggregate and the cement paste requirement for concrete increases with increasing void content of the combined aggregates, it is desirable to keep the void content as low as possible.

Aggregate in precast concrete is a structural filler, but its role is more important than what that simple statement implies. Aggregate occupies most of the volume of the concrete. It is the stuff that the cement paste coats and binds together. The composition, shape, and size of the aggregate all have significant impact on the workability, durability, strength, weight, and shrinkage of the ...

Grading of Combined Aggregate: In a concrete mix, the relative proportions of the fine and coarse aggregates are one of the important factors which affect the strength of the concrete. For dense concrete, it is essential that the fine and coarse aggregates be well graded. The locally available aggregates generally do not conform to the standard grading’s. In such situations the aggregates ...

Effects of aggregate properties on Concrete like Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix, density and porosity. It is an important factor and has a maximum influence on workability. Well graded aggregates result in the least amount of voids in a ...
