It is produced from hard granite stone by crushing. Manufactured Sand Specification. The bulk density is 1.75 gm per cubic cm. The specific gravity of manufactured sand is 2.5 to 2.9, depending on the parent rock. Permissible limit of fines below 75 microns is up to 15%. The controlled gradation of Zone-II is possible, making it ideal for concrete.
M –Sand. M-sand, or manufactured sand, is a material created by crushing rocks and screening them to a specific size. This sand is often used in constructing roads and buildings due to its strength and durability. Unlike natural sand, M-sand contains no organic impurities that could damage structures over time.
