The chemical properties of fly ash are influenced to a great extent by those of the coal burned and the techniques used for handling and storage. There are basically four types, or ranks, of coal, each of which varies in terms of its heating value, its chemical composition, ash content, and geological origin.

Tests were conducted on cubes and beams to study the strength of concrete made of Quarry Rock Dust and the results were compared with the Natural Sand Concrete. An attempt has also been made to durability studies on Quarry Rock Dust when compared with the Natural Sand concrete.

In M25 concrete mix 50% of cement was replaced by fly ash and sand was totally replaced by 50% of quarry dust and 50% of marble powder. Keywords:Green concrete, fly ash, quarry dust, marble powder, compressive strength, split tensile strength.

Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates.

Fly ash typically needs no processing and can be delivered from the power plants directly to the ready mixed concrete producer, where it is mixed with traditional ingredients of cement, aggregates and water.

In addition, it was found that the flowability of sandfly ash mixtures was influenced by such sand properties as fineness modulus and uncompacted air void content. Similarly, other flowable fill properties, such as bleeding, subsidence, penetration resistance, and unconfined compressive strength, were observed to vary with the sand property ...
