The effect of manufactured sand over natural sand results in a slightly higher value of reflectivity as indicated by the spectrophotometer. Using natural sand may result in color changes later due to the effect of iron in the sand, but using manufactured sand will produce a harsher, less workable mix. These results were based on the
River Sand Substitutes. ... – Allternatives to sand like mSand (manufactured sand), copper slag, powdered glass and recycled construction waste etc which are increasingly being used in many EU nations, Singapore and the US should be encouraged in India.
Internationally the described media is manufactured in compliance with ISO 111263. The blasting media manufactured from copper slag brings less harm to people and environment than sand. The product meets the most rigid health and ecological standards. Construction. Copper slag can be used in concrete production as a partial replacement for sand.
This scarcity of natural sand because of environmental issues leads to usage of manufactured sand (MSand) and crusher dust.

Natural Aggregates: Aggregates originated from stone quarries, gravel, sand or igneous/ metamorphic rock deposits. Slag Aggregates: Byproducts formed in the production of iron, copper, and steel. Iron Blast Furnace Slag: A synthetic nonmetallic byproduct simultaneously produced with pig iron in a blast furnace that primarily consists of a fused mixture of oxides of silica, alumina, .
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Know the details of M Sand vs River or Natural Sand. Manufactured sand is a perfect substitute for river sand. These blog covers full details of msand advantages. Impurities and wastage is almost nil.
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

Iron Blast Furnace Slag: A synthetic nonmetallic byproduct simultaneously produced with pig iron in a blast furnace that primarily consists of a fused mixture of oxides of silica, alumina ...
The physical effect is to cause the slag to break up into porous particles, usually called slag sand. This slag sand, as it leaves the vats, contains 15 % to 45 % (usually 30 % to 40 %) of adhering water. The expense of drying the slag sand is the chief disadvantage of watergranulated slag.
