Effect of aggregate on the fracture behavior of high strength concrete
It is suggested that the high-strength concrete with lower brittleness can be made by aggregate with greater size. 2. When aggregate volume increases from 40% to 80%, GF and KIC of low strength concrete increase. While for high strength concrete, the maximum values of GF and KIC are achieved at 60% of aggregate volume.

How to Choose Quality Coarse Aggregate for Concrete Construction?
To ensure good coarse aggregate compaction and higher concrete density, it is recommended to mix 20 mm and 10 mm coarse aggregates in the ratio of 70:30 or 60:40. It is recommended to stack different aggregate sizes to use them efficiently. Prevent the use of friable and chert aggregates. The former is susceptible to splitting, whereas the ...

Aggregate Properties You Need to Know: Strength & Durability
Construction aggregates are mineral materials used in the production of construction materials such as Portland cement concrete and hot-mix asphalt, and as unbound base courses for pavements. In their primary role as filler in these materials, the volume of aggregates can take up 90 – 95% of asphalt and 70 – 80% of concrete mixtures.
