M-Sand is manufactured sand, obtained from specific hard rock (granite) using the state-of-the-art International technology. Its numerous advantages over river sand have made it a favorite and a "Must-to-Use" with quality conscious builders.
Poabs M-Sand is cubical in shape and is manufactured using international technology like High Carbon steel hit rock and then ROCK ON ROCK process which is synonymous to that of natural process undergoing in river sand information.
Poabs is always been the first to introduce these technological bliss for the good use of the construction industry in South India. In line with the manufacture of sand in bulk quantity, Poabs have procured the world's best and state of the art equipments and installed them at various safe stations in Kerala complying with every scientific parameters set for producing Manufactured Sand(M-Sand). Modern and imported machines VSI(Vertical Shaft Impact) are used by Poabs to produce M-Sand, ensuring to IS 383 ZONEII. For quality control, Poabs has engaged in a scientific tie-up with the RND lab and department heads of Trivandrum Engineering College who rigorously and constantly monitor our production at every stage. This exceptional kind of technical support always assures us to maintain consistency in quality as well as to upgrade our technology from time to time.
The particle shape of the aggregates is very important for making concretes. It is a well known fact that the sand having cubical particles with grounded edges gives higher tensile strength and compression strength to the concrete. The grains should be of durable material and the size of the grains must be such that it should give minimum voids. The presence of clay and slit is avoided since it retards the setting of the cement and making mortar. Experiments shown that considerable variations in strength of mortar may occur owing to form and variety of the sand particle. The strength of mortar may differ by about 50% of average. 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.
The manufactured sand produced by proper machines can be better substitute to river sand.
There is discrepancy in the river sand for two loads lifted from same source. Hence to achieve consistent quality, each truck of sand should be tested. Moreover the sand has to be sieved to remove stones, slit and clay. In routine average wastage of sieving are about 35% and extra labour cost involved. Whereas Poabs M-Sand is ready-to-use-sand with no wastage since it do not have organic impurities. The superior shape and gradation of Poabs M-Sand ensures high strength concrete with significant savings in cement.
