How Coarse Aggregate Affects Mix Design of Concrete?

17/08/2019  Smaller maximum size of coarse aggregate would require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix. So, for the same workability, 40mm down aggregate would have lower water/cement ratio, thus higher strength when compared to 20mm down aggregate. Because of its lower water demand, advantage of higher maximum size of coarse aggregate

Practical Grading of Aggregates Concrete Technology

In general, finer the grading of the fine aggregate, higher should be the coarse/fine aggregate ratio. Typical values are shown in Table 4.23. On the other hand the coarse sand of zone I produces a harsh mix and a high content of sand may be necessary for higher workability. This sand is more suitable for rich mixes or for use in concrete of ...

Coarse Aggregate in Concrete Construction Shyam Steel

The size of coarse aggregates affects several aspects of the concrete, mainly strength and workability, and the amount of water needed for the concrete mix. It also helps determine how much fine aggregate is needed to produce a concrete batch. The bigger the size, the smaller is its bondable surface area for cement, sand and water; the less water and fine aggregate is needed with concrete mixes.
