What is M-Sand?M-Sand is manufactured sand

M-sand is crushed aggregates produced from hard granite stone which is cubically shaped with grounded edges, washed and graded with consistency to be used as a substitute of river sand.

Quality Assurance:-M-Sand is superior quality manufactured sand with international standardsVasthu Shastra Says Building material must be free from traces of human body or animal. M-sand is free of such material and is produced by crushing hard granite stone when compared to river sand that is produced naturally from weathered rock.M-sand adheres to the highest standards and the quality tests are done by the College of Engineering, Trivandrum.


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.

Rock blasting & Loading

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 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).Primary Jaw CrushingSecondary Cone Crushing

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.

Why manufactured sand?Globally, natural sand and gravel extraction is becoming less of an option. New pit location opportunities are fewer, further from the marketplace and harder to secure. In the past, natural sand and gravel extraction has been the backbone of the aggregate industry; this is increasingly less the case. Operators now wish to produce high-quality manufactured sand.
