WHAT IS THE IMPORTANCE OF AGGREGATE GRADATION IN CONCRETE ...

Jun 25, 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.

Concrete Mix Design: Types, Advantages Disadvantages

Concrete mix design with an excessive water-cement ratio, larger maximum size could also be helpful. Grading of Mixed Aggregate: The relative ratio of fine and coarse aggregates in concrete mixtures is a vital issue affecting the strength of concrete. For dense concrete, it is necessary that coarse and fine aggregates are nicely categorized.

Effects of Aggregate Properties on Concrete - Size, Grading

Effect of Grading. 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.
