The advantage of using a hard rock crusher fine is that all of the material that makes up the mix is from rock, and because it’s been crushed, the sides are all fractured (six sided fractured aggregate) In a sand and gravel deposit, there are naturally occurring aggregates in sizes from sand up to boulders
The analysis also revealed that the replacement of sand with more than 30% crushed granite fine will result in the production of concrete that is uneconomical when compared with the use of crushed granite and river sand as coarse and fine aggregate respectively
and mortar compared to the use of alternatives such as crushed rock fine • The use of river sand would, for a given workability requirement, reduce the water demand and/or superplasticizer demand, and thus allow a lower water content and a lower cement content to be adopted in the mix design
