Manufactured Sand & Plaster Sand
Manufactured Sand is manufactured by proper crushing of aggregates into finer materials of required particle size (generally using VSI technology). Since quality control is maintained in the process of preparing manufactured sand, the sand obtained will better confirm to the Zone-II grading standards at all times. The don’t have any organic or silt materials.
Pit sand is extracted from Deep pits dug underneath the ground. It usually have a coarser grain size. It is not recommended in construction activities as the particle size is too large.
