Sep 01, 2018· Aggregates. Aggregates are used to give body and strength to a concrete or mortar mix. Coarse aggregate is small stones, usually less that 20 mm in diameter, and fine aggregate is basically sand. Sharp Sand (which has larger grains) is used for concreting or laying paving slabs and Soft Sand is used for bricklaying, etc.

In general, if the water-cement ratio is kept constant and the ratio of fine-to-coarse aggregate is chosen correctly, a wide range in grading can be used without measurable effect on strength. However, the best economy will sometimes be achieved by adjusting the concrete mixture to suit the gradation of the local aggregates.

Effect of Aggregate Cement Ratio on Workability of Concrete. Aggregate cement ratio is the ratio of weights of aggregate to the weight of cement. If this ratio is more, that implies aggregates are more and cement is less and if this ratio is less, that implies weight of aggregate is less and weight of cement is more (relatively).

Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio. The same is governed by particle size and shape of aggregate used. A flaky and elongated aggregate will demand higher cement content (as they have higher surface area for the same ...

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

At a given water ratio, within the range employed in most structural concrete, smaller maximum sizes of aggregate will tend to produce higher concrete strengths than larger ones. 2. The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower water-ratio than the smaller sizes. 3.
