2021-11-23 Manufactured 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.

Manufactured sand differs from natural sea and river dredged sand in its physical and mineralogical properties. These can be both beneficial and detrimental to the fresh and hardened properties of concrete. This paper presents the results of a laboratory study in which manufactured sand produced in an industry sized crushing plant was characterised with respect to its physical and ...

2016-6-2 For the manufactured sands, the sands with a -B notation were mixed to achieve the same S2 slump as the control and the required water/cement ratio was recorded. That w/c ratio was then kept constant for the remaining gradings of the same quarry sand, recording the change in slump observed in each concrete mix.
