WhatsAppGet PriceGet A QuoteManufactured sand can be considered as a by-product of the process of producing coarse aggregates. When the rock is crushed into small particles, fine aggregates are produced. Due to the increasing demand in the construction sector, there is a difficulty in supplying the rever sand continuously to meet the demand.
WhatsAppGet PriceGet A QuoteFirst, 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.
