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.

Jun 01, 2010· – A current trend is to use waste and by‐products in concrete to replace binders and aggregates. This trend reduces the impact on the environment and the use of finite natural resources. This paper aims to investigate whether concrete which includes crushed, graded and washed recycled construction demolition waste, used as a coarse aggregate, can be manufactured to a comparable .

Aggregates | Concrete

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and Portland cement, form the ingredients in concrete. Aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of fine materials that could cause deterioration.
