  • Suitability of Crushed Manufactured Sand for Replacement of .

    Abstract. The global consumption of natural sand is very high, due to the extensive use of concrete or mortar. The fine and coarse aggregates generally occupy 60% to 75% concrete volume (70% to 85% by mass) and strongly influence the concrete's fresh and hardened properties. Now a day's sand is becoming a very scarce material.
