What kind of sand do you use for a roof?
For Roof (RCC) work M-sand is the best option. Following are the resign why this is best for Roof (RCC). It is well graded in the required proportion. It does not contain organic and soluble compound that affects the setting time and properties of cement, thus the required strength of concrete can be maintained.
Which sand is suitable for concrete?
Masonry sand is a fine-grained, pure type of sand utilized in the creation of concrete or mortar. This type of sand is mostly used in laying bricks, stones, or blocks, thus making it perfect for patio construction.
Can you use M sand roof concrete?
Yes, M-Sand (crushed sand) can replace 100\% river sand in a concrete mix proportion. Since quality control is maintained in the process of preparing manufactured sand, the sand obtained will better confirm to the Zone-II grading standards (required by IS code for concrete works) at all times.
How do I choose sand for concrete?
Guidelines for Selecting Good Sand That can Be used for Construction
- Silt Content should be less than 3\% by weight (12\% by volume in 10 min)
- Sand should be free from Organic materials.
- Sand shall not contain any harmful impurities such as iron, pyrites, alkalies, salts, coal or other organic impurities.
Which sand is better for slab?
River sand or Natural sand They are mainly used in concrete and masonry work. They can also be used for RCC, plastering, and much other brick or block works. This sand consists of a smoother texture and a better shape of grains. The river or natural sand demands very less water.
Which is better sand or river sand?
The shape of Crushed sand is angular and cubical and has a rough texture and hence, better for concrete. The shape of natural sand is rounded and has a smooth surface. This sand highly recommended for RCC purposes and brick/block works. River sand is recommended for RCC, plastering and brick/blockwork.
