  • Crushed Sand vs Natural Sand: Make the Right Choice!

    01/12/2016· As the supply of suitable natural sand near the point of consumption is becoming exhausted, the shortage of good natural sand for concrete production is facing challenges The construction industry has a huge need to solve this challenge This is also resulting in poor qualities of sand, particularly containing silt They need to solve this challenge by using crushed sand inThere are two reasons for the sometimes high price for natural sand compared to crushed aggregate: First, a good quality sand can have a huge impact on the cement consumption (the highest share of concrete selfprice) needed to produce concrete with desired properties; second, the availability of good natural resources is almost exhausted in many parts of the world This turns the spotlight onNew type of crushed sand to replace natural sand in12/01/2020· The Concrete has been traditionally made with use of Natural / River sand as fine aggregate As sand contributes to around 25 to 35% of total concrete along with coarse aggregates, cement & water, the properties of the fine aggregates would be one of the major influencing factor in determining the fresh & hardened Concrete Read More »Use of Crushed Stone sand & its impact on ConcreteUse of Crushed Stone sand & its impact on Concrete
