Concrete Mix Design Data:(a) Characteristic compressive strength of concrete required at end of 28 days = M 25 (b) Nominal maximum size of aggregate used = 20 mm (c) Shape of Coarse Aggregate = Angular (d) Required workability at site = 5075 mm (slump Value)

Effects of Aggregate Properties on Concrete Size, 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. Well graded aggregates result in the least amount of voids in a ...

How Coarse Aggregate Affects Mix Design of Concrete?


Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture. It is reported [.]

Factors Influencing Choice of Mix Design • According to IS 456:2000 and IS 1343:1980 the important influencing the design of concrete mix are • Grade of Concrete • Type of Cement • Maximum nominal Size of Aggregate • Grading of Combined aggregate • Maximum Water/ Cement Ratio • Workability • Durability • Quality Control.

Importance of aggregate grading The Concrete Society


Importance of aggregate grading. Ideally coarse and fine aggregate should be graded in such a way as to minimise the voidage. After compaction the volume of the cement paste must be more than the voidage between particles. Underfilling will result in entrapped air and an unworkable mix. An extreme example of this is a nofines concrete where the sand fraction is minimised, the course aggregate ...

Mix Design for Pumpable Concrete | Materials | Concrete ...


To produce good quality pumpable concrete, a good grading of aggregate is necessary. Flaky and elongated aggregate will produce harsh concrete for the given cement content and water/cement ratio. The grading curve of the aggregates to be used in the proposed mix should be parallel to the curves of, but not coarser than curve no. 2.
