Artificial sand made by suitable machines is often an excellent alternative to river sand. The sand should be sharp, clean and of course. Grain should be of durable material. The size of the grain should be such that at least weeds should be given. The presence of clay and silt cancels the alignment of the cement and weakens the mortar and therefore the walls or slabs leak and get wet.
The sand inside the mortar adds no strength but is used as a precursor to the economy and with the equivalent it prevents the mortar from shrinking and cracking in the setting. Sand must be properly numbered (it must have the right proportions from 150 microns to proportion.75 mm) When the fine particles are in the right proportions, the sand will have fewer weeds. When there is less void in the sand the required cement will be less. Such sand would be more economical.
Mortar has no plasticity. So masonry is not able to work with crushed stone sand made from machines. For the same reason, secondary river sand could also be used. Sand production from jaw crusher, cone crusher, roll crusher often has a high percentage of dust and contains flaky particles.
