M Sand, also known as manufactured sand, is an artificial sand produced by crushing hard stones and passing them through a VSI (Vertical Shaft Impact) machine to produce small sand-sized particles.
M-sand originated as a solution to address the scarcity of natural river sand for construction purposes. It was first introduced in Tamil Nadu and Kerala as an alternative to traditional river sand in response to the increasing demand for construction materials and concerns about environmental impact. Over time, it has gained popularity as a viable alternative for construction and concrete mixing. In this type of sand 20mm, 10mm, 6mm stone sizes are available.
Despite its growing use, M sand is not the preferred option due to certain drawbacks, which will be addressed later in this article.
