Eco-Friendly Alternatives To Traditional Concrete

Jul 18, 2019· Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world’s most widely used material for construction from bridges to large buildings, concrete forms the very foundation of our

What are the Materials for Replacement of Sand in Concrete

Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.

What are the Sources of Natural Aggregates?

Aggregates are the most important constituents in concrete.They give body to the concrete, reduce shrinkage and effect economy. Natural aggregates are inert granular materials such as sand, gravel stone or crushed stone that are used with a binding medium i.e. water, bitumen, portland cement, lime, etc. to form compound materials i.e. asphalt concrete and portland cement concrete.

Cut-price concrete substitute Aggregate Research

The new material is lighter, stronger and less expensive to produce than concrete. It does this while using three times as much fly ash, thus tripling the amount of the pollutant that is converted from waste into useful material. The new company goes by the name of Acrete, a combination of “Arizona” and “concrete.”
