Effect of Size. The grading or size distribution of aggregate has a considerable effect on the properties of concrete as it determines the paste requirement for workability of concrete. The paste also affects the cost of the mix as cement is the most expensive component in the mix. Hence, it is required that optimum size of aggregates is used

Crushed stone #411, which is a mixture of #57 stone and coarse rock dust, is a good option for road top layer. This blend of small stones and rock dust will fit tightly together as the stones settle, forming a stable, solid surface that can stand up to heavy vehicles. The crushed stone #411 is crushed by a mobile rock crusher.

If, however, the two mixes are designed for the same slump and workability, and with the same cement content, the mix with l/2-inch aggregate is likely to be somewhat stronger, because its water-cement ratio will be lower. However this increase in strength may not be significant because of other factors that affect strength.

For example, if you like the look of natural stones or fresh concrete, you can use crushed concrete to create the base for your driveway, installing your preferred surface materials on top. This uses less expensive material and still adds some permeability to your driveway, depending on how it’s designed.

The specification of crushed concrete aggregates (CCA) is increasing, particularly for low-grade applications, where quality is of less importance. In higher value applications, such as structural concrete, further research is required to understand the effect of CCAs on mechanical and durability performance. One disadvantage of using CCA is that the fine material (0-4mm) is often removed
