Pervious Pavement :: Pervious Concrete for Green

Placing the pervious concrete over a 6-inch (150-mm) layer of 1-inch (25-mm) maximum top size aggregate provides a pavement base, stormwater storage, and isolation for the pervious concrete. Unless these precautions are taken in aggressive environments, recommendations from ACI 201 on water-to-cement ratio and material types/proportions should

What is concrete? Properties, Uses, Advantages

In concrete sand is used as fine aggregates, gravels and crushed stones are used as coarse aggregates. The cement acts as a binding material which forms a paste with water and on hardening, this cement paste holds coarse and fine aggregates together to form a solid mass. Properties of Concrete. The cement concrete possesses the following

Concrete in Construction: Uses, Advantages, and Types

In the world today, concrete has become a fact of modern life. Six billion tons of concrete are used around the world each year. The addition of sand, fine aggregates and coarse aggregates of up to a few centimeters makes concrete. It is a porous material whose properties depend on its different kinds of pore space.

Mix Design - Self-Consolidating Concrete

Mix Design . SCC looks very different from conventional concrete while mixing. Concrete producers must "retrain their eyes" for this very fluid mixture as it turns corners and fills forms. Traditionally, concrete with the fluidity of SCC has had a very high water-to-cement ratio, which would lower compressive strengths and compromise
