Effect of Aggregate Size and Water-to-Cement Ratio on the Mechanical Properties of No Fine Aggregate Concrete

The mechanical properties of No-fine aggregate concrete are investigated. This paper consists of two parts: In the first part, three sizes of aggregates (9.5 mm, 12.7 mm, and 19 mm) with two water-to-cement ratios (0.4 and 0.45) were examined. In the second part, specimens made with recycled concre...

description The mechanical properties of No-fine aggregate concrete are investigated. This paper consists of two parts: In the first part, three sizes of aggregates (9.5 mm, 12.7 mm, and 19 mm) with two water-to-cement ratios (0.4 and 0.45) were examined. In the second part, specimens made with recycled concrete aggregate with a replacement ratio of 30% by the weight of normal aggregate and a steel fiber of 35 kg/m3 were examined in two water-to-cement ratios (0.4 and 0.45), and an aggregate size of 12.7 mm. The effect of the cement-to-coarse aggregate ratio was also studied; three different ratios (1:2, 1:4, and 1:6) were examined. This study found that the increase in aggregate size and the water-to-cement ratio harmed the compressive, splitting tensile strength, and unit weight of the NO-fine aggregate concrete. The study also found that the compressive and splitting strength declined using recycled concrete aggregate; however, using steel fiber with recycled concrete aggregate improved both.
