Influence of Manufactured Sand of Different Production Processes on Concrete Performance

The workability, compressive strength, splitting tensile strength, compressive modulus of elasticity and carbonization resistance of concrete prepared with dry-processed manufactured sand (M-sand) are better than those of ordinary manufactured sand. In the case of little difference in workability, dry-process manufactured sand can save the amount of water-reducing agent, and manufactured sand produced by different production processes has the same effect on the electric flux of concrete.

Essentials of Process Design for Aggregate Crushing Plant

In view of the above characteristics of the sand and aggregate processing plant, the key to the process design is to make a comparison of various plans. Designed from the perspectives of the stability of production and operation (dry method, wet method and combination of dry and wet), product quality stability (selection of auxiliary equipment such as crushing, screening, sand making equipment, conveying equipment), investment cost and operating cost Develop the optimal process plan.
