  Suitability of Crushed Manufactured Sand for Replacement of Natural River Sand to Produce C-25 Concrete
  Author(s): Dessalegn Mamaru*
  
  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. Natural sand deposits are being depleted and causing serious threats to the environment and society. The culture of using alternative ingredients to produce materials is weak in Ethiopia. Around Jimma town, quality sand is not readily available and it is transported from Worabe, Gambella, and Chewaka that needs high transportation costs. In this situation, research began for an inexpensive and easily available alternative material to natural sand. The main objective of this study was aimed to determine the fresh and hardened properties of C-25 concrete by repl.. Read More»
