According to the IS-383, the chemical characteristics of M-Sand are somewhat similar to river sand. Several properties such as setting, compressive strength and permeability are enhanced in M-Sand, though it has low water retention and workability and tends to crack more often. Certain remedies can be put in place that can curb these said flaws. IS-383 mandates several specifications such as higher crushing strength for the sand, and before the final stages of production the M-Sand particles undergo processing. During this process, the particles are stimulated and crushed to a certain size, resulting in particles with superior shape and smooth surface texture. The particles are further refined by removing fine particles and impurities through sieving and washing.
Faster Setting, Minimal Defects, Optimum Size
Higher Bond Strength, More Compressive Strength, Low Permeability.
Minimal Defects, Lower Royalty Rates, Utilization of Bi-Product.
An accelerated pace of growth has increased the demand-supply gap when it comes to river sand. Thus, making M-Sand an ideal alternative to meet the needs of the construction sector.
Concrete contains around 65 to 80% sand. Due to comparable bulk densities of M-Sand and river sand, M-Sand can replace river sand. Moreover, easy availability of M-Sand makes it the preferred choice.
Licensed sand leases producing the required quality of sand are often located in remote locations, leading to high costs in transportation.
It can be damaging for screed and concrete, if the sand is not processed to bring down clay and other impurity contents to acceptable levels.
The low value aggregates formed as a by-product of rock crushing can be utilised efficiently to create a high-value product.
