Which sand is used for waterproofing?

Depleting natural resources, shortage of natural sound (river sound) & exhorbitant prices of sand have led to the creation of an innovative system, where guaranteed water proofing can be done using zone-2 crushed sand (some quality of sand which is used in RCC work).

Which is better m sand or sand?

M Sand has higher Fineness Modules Index compared to the natural river sand, which gives good workability for concrete. M sand is free from silt and clay particles which offer better abrasion resistance, higher unit weight and lower permeability.

Will M sand absorb water?

The results of testing the specific gravity of M-Sand and water absorption show that the dry specific gravity in the test was 2.76 and the specific gravity under SSD (Saturated Surface Dry) conditions obtained was 2.79. Meanwhile, the test results of water absorption of 1.01\%.

Is M Sand good for plastering?

Plastering M Sand is used for Wall plastering and brickwork purposes. The granule thickness is 150 microns to 4.75 mm and is suitable for concrete preparations required for construction purposes. The granule thickness is 150 microns to 2.38 mm is ideal for block masonry and plastering purposes.

Is crushed sand good for construction?

Crushed Sand (Manufactured Sand) It is highly recommended for RCC and brick/ block works.

What is difference between crushed sand and manufactured sand?

Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm.

Can we use M sand for concrete?

Advantages of M-sand The major advantage of manufactured sand is that it is highly cohesive and compressive in strength. It has lesser impurities, which help in producing better quality concrete. Moreover, the controlled gradation of Zone-II is possible, suitable for concrete.
