Figure 2 above shows the compressive strength test results of all the mix ratios employed in this work. It is observed that concrete,Effect of Aggregate Maximum Size upon Compressive,26/09/2020· It was noticed that concrete made with 20 mm maximum aggregate size has 45.7% compressive strength higher than that made with 10 mm maximum aggregate size [8].The Effect of Aggregate Properties on Concrete,The compressive aggregate strength is an important factor in the selection of aggregate. When determining the strength of normal concrete, most concrete aggregates are several times stronger than the other components in concrete and therefore not a factor in the strength of normal strength concrete. Lightweight aggregate concrete may be more influenced by the compressive strength of the,Factors affecting Concrete Mix Design - Happho,In general, larger the maximum size of aggregate, smaller is the cement requirement for a particular water-cement ratio, because the workability of concrete increases with increase in maximum size of the aggregate. However, the compressive strength tends to increase with the decrease in size of aggregate.
