EFFECTS OF COARSE AGGREGATES GRADINGS ON THE PROPERTIES OF CONCRETE

چکیده
Coarse aggregates gradings have varying effects on the properties of concrete. sizes 10mm, 20mm and 25mm were used for this study. Sieve analysis was conducted these aggregates. Their coefficients curvature (Cc) ranged between 1.01 1.19, while uniformity (Cu) 1.24 1.73, showing that they are all uniformly graded. 10mm coarse mixed in various proportions to produce five different concrete mixes (concrete C1, C2, C3, C4 C5). Concrete C6 produced with 100% as a check. Slump test performed each mixture, C1 gave highest slump height 88mm. Compressive strengths cast cubes determined after 7- 28-days curing periods. maximum compressive strength 26.33N/mm2 at 28 days. Increase percentages resulted higher decreased workability.
