High-Strength Concrete with Crushed and Natural Sand

Two different sand types were used: natural and granitic crushed sand. Proportions 0, 25, 50, 75 and 100 % were selected to obtain blended sands with continuous changes in their physical and mineralogical characteristics. The properties of concrete were evaluated with these five blended sands. From the research and studies performed up to five years, it was shown that the use of granitic crushed sand in high-strength concrete.
