Influence of Manufactured Sand of Different Production Processes on
The dry-process manufactured sand only needs to add 2.23kg/m³ of water-reducing agent, which saves 23% of the water-reducing agent. At this time, the slump of concrete prepared with dry-process manufactured sand is 15mm larger than that of ordinary manufactured-sand concrete. The expansion degree is 65mm larger.

Manufactured sand – a solution to the global sand shortage?
First, manufactured sand is more uniform in structure compared with natural sand. It also has an advantage when it comes to concrete production, because manufactured sand is less needed in the concrete mix by a margin of 5 to 20% compared with natural sand to fill the voids volume between the particles.

Manufactured Sand for Construction
Manufactured sand (M-Sand) is used as a substitution to the river sand in construction. River sand is becoming a decaying resource in some parts of the year due to the lack of rains to collect the sand on the river beds. Manufactured sand can be considered as a by-product of the process of producing coarse aggregates.
