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

Tikrit Journal of Engineering Sciences
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.
