The aid of abrasives that used in crushing cement clinker has a significant effect on the process efficiency, reducing energy consumption, saving time, increasing production capacity, improving the properties of cement and concrete resulting from it, and reducing costs ... . The purpose of this research is to investigate the effect of type and amount of abrasive aid on cement crushing and compressive strength of concrete. For this purpose, samples were prepared from the cement clinker , pozzolan, perlite, pumice and organic abrasives (with different weighing percentages), and their blaine number was measured. Then, by constructing concrete blocks under constant conditions, the combination of water and aggregates and different cement compounds, on them, the determination of compressive strength at different ages of 2, 3 and 7 days was carried out on them. In all cases, the use of abrasive aid increased the number of blaine (the degree of softness of the cement) and reduced the compressive strength of the concrete. The mixing plan of 85% of clinker and 15% of pozzolan resulted in the highest amount of cement blaine at 4546. The greatest drop in resistance (of all ages) is related to the block containing perlite abrasive aid. Over time, the compressive strength of the concrete has increased with various abrasives aids. The combination of 15 wt% pozzolan, 85% clinker, 4% gypsum and 3 grams of organic abrasive abrasive was the optimum cement clinker composition, which caused the least resistance to the other conditions. In this case, the 2-day resistance of the concrete with abrasive aid increased by 3% compared to the non-abrasive concrete, while the 3 and 7-day strengths decreased by 8.9% and 13.13%, respectively.
