mixing process in 20mm and 10mm coarse aggregate

differences in concrete properties using 10mm to 20mm ...

Dec 16, 2014  Depending on the mix design, either can be used to make essentially any range of concrete strengths. When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate.

Aspects of Concrete Mix Design

the coarse/fine aggregate ratio which ultimately has a bearing on the cement content. There are different approaches as to how coarse aggregates are proportioned. One method is to mix together 20mm and 10mm aggregate in a range of blends to find the combination that gives the maximum density and corresponding minimum void space to fill.

Why do some concrete mixes include both 10 mm and ... - Quora

Answer: Why do some concrete mixes include both 10 mm and 20 mm aggregate when others would only include 1 size? It depends on available materials, and the purpose for which the mix design is made. Some batch plants do not have sufficient number of bins for multiple sizes of coarse aggregate

Other than that, having the proper size of aggregates matters as well. For instance, concrete mix A is using the maximum size of 10mm of coarse aggregates in the mixing, while concrete mix B is using the maximum size of 20mm of coarse aggregates, the workability for concrete mix B will most likely be higher since having a greater size of coarse aggregates will require lesser binders, known as ...
