This study investigated the effect of fly Ash in percentages (20-70%) of the weight of the cement that the resistance of compression and flow of cement mortar. The experimental work study the reference mix (without the use of additives) to be referenced and compare the results of the rest of the mixes with them. A series of cement mixtures were used in which a fixed percentage of water to cement (0.5 w / cm) and fly ash were used in different proportions and added to different grades. The compressive strength of the cement mortar was calculated at the age of (7, 28 and 56) days. The results of the tests were also checked for the mixtures using fly ash with the reference mixture. The highest compressive strength was found at 30% Fly ash and maintain the flow of the mixture by adding plasticizer up to (1.8)% of the weight of cement.
