Webbproportions. The fresh concrete was caste into molds(100 mm × 100 mm × 100 mm) after slump test. All specimens were demolded after 24h of casting and then cured in a moisture room at 20 ± 2 C and 90 ± 2% relative humidity (RH) until 3 days, 7 days and 28 days. Three specimens at each age were used for compressive strength Webbslump flow value gives higher workability of concrete. Therefore, the first criterion having effects on concrete quality is the slump flow value which should be maximized.
