The strength of mortar may differ by about 50% of average. Sand particles should however be hard for more strength. It is not possible in river sand, that all particles should be of higher strength. This can be achieved only by making sand with the help of machines. In machine made sand we can use the raw material of higher strength.

Cement performance is intially set by targeting a clinker lime saturation factor (LSF). This gives the required product strength but also provides good clinker burnability and reasonable economy of operation. The LSF level is often around 95 or 96, although the optimum LSF will vary depending on the raw material properties and other factors.
