Abstracts: We have under-taken the project for “fly ash concrete” which will adding fly ash materials for effective compressive strength and improve workability of concrete. We have partially replaced Portland cement in mix 1 & 2 & 3 by 10%, 20% & 30% respectively fly ash adding to M25 and M50 grade OPC cement. We containing fly ash with difference proportions 1:1:2 additions to OPC will investigated and tested for compressive strength age of 7 and 28 day. Three cubes of 150 x 150 x 150 mm size were tested on compressive strength was reported. Use aggregate size of 20mm and other depended on usually. We will use the IS CODE 10262:1982 as reference. We have tested different types of concrete materials which are related to fly ash with absolute results and conducting various types admixtures of fly ash in concrete.
