The Effect of Aggregate Properties on Concrete

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

Effects of Aggregate Properties on Concrete - Size, Grading

May 02, 2017  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 ...
