AbstractTrial laboratory batches were used to study the effect of adding different amounts of superp lasticizers on the mechanical properties (Compressive strength, abrasion resistance, and impact resistance) of concrete. A series of five different concrete mixtures including: Normal concrete mixture C1 (without superp lasticizers) as a reference mix and four concrete mixtures (C2, C3, C4, and C5) with different amounts of superp lasticizers (0.25, 0.50, 0.75, and 1.00) % as a percentage of cement content, respectively. Results show that the (1.00)% addition of superp lasticizers in the concrete mixture leads to (19.84)% increasing in the compressive strength and records an improvement in the abrasion resistance by (38.06)% and recorded an improvement in the impact resistance by (386.67)% as compared with the reference mixture. On the other hand, increasing the percentages of superp lasticizers lead to increase in compressive strength, abrasion resistance and impact resistance for all concrete mixtures.
