The ingredients (i.e. cement quarry dust with /without fly ash) were drily mixed initially in a mixer for approximately 5 min. at low (30 rpm) and high speed (60 rpm). The mixing water was halved and added to the dry mixed mixtures and remixed again at low and high speeds for almost 3 min.
206-1. Fly ash according to EN 450-1 may also be used in mortars and grouts. 3. Reference list ≡ EN 450-1 Fly ash for concrete – Part 1: Definition specifications and conformity criteria including annex ZA.

Concrete is a mixture of cement fine aggregate coarse aggregate and water with or without additives. Concrete can be made with substitution of cement with materials like Fly Ash CaCO3 and silica sand that can increase the binding on pasta and also increase the compressive strength of concrete. The Superplasticizer on a mixture is used to reduce the high water content improve concrete .
Cement placed by means of Fly ash concrete mixes prepared with 20% 30% 40% weight of cement and using16mm diameter steel bar 100mm length with 25 mm clear cover were used as samples.
study concrete with 50% fly ash replacement and 10% quarry dust replacement instead of cement and fine aggregate proves to be more beneficial as well as economical. Keywords: Fly Ash Quarry Dust Strength 1. Introduction Concrete is the most commonly used building material all over the world. It is estimated that a total of 4.3 billion tonnes
Fortunately these byproducts can be used in civil engineering construction. In this research samples of fly ashes from Soma B thermal plant (Turkey) were mixed with different amounts of normal portland cement dehydrated lime and bottom ash (slag) to form a new material for bricks or construction panels.
