Which sand is best for building?
Pit sand
Pit sand is a types of sand used in construction that is best used for constructing buildings due to its superior binding property. It is coarse sand that is found 2-3 meters under the ground. It is obtained naturally from deep pits.
What type of sand is best 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.
Which sand is best 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).
What is difference between Robo sand and dust?

What are the disadvantages of sand?
The advantages and disadvantages of sand casting
| Advantages of Sand casting | Disadvantages of Sand casting |
|---|---|
| Low cost Casting molds | Low strength |
| Lower production costs | Low dimensional accuracy |
| Wider material choice | Rough surface quality |
| High complexity shapes | More casting defects |
What is the disadvantage of workability in manufactured sand?
Disadvantages of Manufactured Sand Due to its smooth and angular textures, leads to more water and cement requirement to achieve the expected workability, thereby increase in overall costs. If the M Sand contains a large number of micro fine particles, it can affect the strength and workability of concrete.
How can you tell the quality of sand?
Take a Sample of sand and add it in Sodium Hydroxide [NaOH] Solution, Stir the solution for few minutes, if the color of solution changes to brown, then the sand has organic impurities which are not suitable for construction. Good quality of sand shows lighter color when it is mixed with NaOH solution.
Which type of sand is not recommended for structural concrete?
Sea sand does not have high compressive strength, high tensile strength etc so it cannot be used in construction activities. In addition to this, the salt in sea sand tends to absorb moisture from atmosphere, bringing dampness. Dr.

- EPDM Rubber.
- Rubberized Asphalt.
- Thermoplastic.
- Bituminous Membrane.
- PVC Waterproofing Membrane.
What are the pros and cons of using robots?
They do not need breaks: Robots use power and gasoline in some cases to perform their duties. This means that as long as there is power to power the robot, they do not require any breaks in between jobs. 8. They can operate in harsh conditions effectively: Robots do not know the difference between harsh conditions and conducive conditions.
What are the pros and cons of wood vs concrete?
Warmth: Wood generally gives off a warmer feeling when compared to concrete or steel materials. This is because the amount of energy to change the temperature, or specific heat, of wood is almost twice that of concrete and three times that of steel. Maintenance & Repair: Wood is easy to maintain and repair.
What are the advantages of using m sand over river sand?
Smoother texture with better shape. Demands less water. Moisture is available only in water washed M Sand. Moisture is trapped in between the particles which are good for concrete purposes. Higher concrete strength compared to river sand used for concreting. Minimum permissible silt content is 3\%.
What are the pros and cons of using glass as building material?
