What Is Artificial Stone?
Artificial stone, also known as cast stone is produced from cement, sand, and natural aggregates such as crushed stone with desired surface finish. Sometimes, suitable pigments may also be added to obtain certain color. But the addition of coloring pigments should not exceed 15% by volume. The proportion of cement and aggregates in artificial stone is 1:3.
Types Of Artificial Stone
The different types of artificial stones are as follows:
- Concrete Block
- Ransom Stone
- Artificial Marble
- Bituminous Stone
- Victoria Stone
- Imperial Stone
- Garlic Stone
1. Concrete Block
Concrete blocks are made from a mixture of cement, sand, aggregates, and water. They are cast at construction sites for piers or cast in mold for walls, steps, sills, windows, etc.
2. Ransom Stone
Ransom stone, also known as chemical stone is prepared by mixing soda silicate and cement. These stones provide pleasing and decorative flooring. The compressive strength of ransom stone is 32 N/mm2.
3. Artificial Marble
Artificial marble is made from marble debris, crushed stone powder, cement, sand, gypsum, and unsaturated polyester resin after molding, grinding, and polishing are made. Artificial marbles are available in various colors. They have a uniform and more polished look than natural marble. Artificial marbles are very costly and are used for external works.
4. Bituminous Stone
Bituminous stones are produced by impregnated granite and diorite with refined tar. These stones are used to provide noise, wear, and dust-resistant stone surfaces.
5. Victoria Stone
Granite pieces with the surfaces hardened by keeping submerged in soda silicate for 2 months to form victoria stones.
6. Imperial Stone
Imperial stone is an American-made artificial stone that comes in 5 colors. It has the look of natural stone with white veining. It provides unique stone tile looks and designs.
Imperial stone is similar to victoria stone. It is produced by mixing finely crushed granite with portland cement. The mixture is molded in desired shape and then stem cured for 24 hours. The cured blocks are finally submerged in silicate tanks for 3 days.
7. Garlic Stone
Garlic stone is produced by mixing iron slag with portland cement and molding it into desired shape. Garlic stones are used as flag stones, surface drains, etc.
Advantages Of Artificial Stone
The advantages of artificial stone are as follows:
1. Artificial stone can be molded into any complex form.
2. Cavities can be kept to convey pipes, electric wires, etc.
3. Strong and durable than natural stone. Its service life is relatively long.
4. Artificial stones are more resistant to abrasion, acid, high temperature, impact, press, flexural, and osmosis.
5. It has a certain temperature resistance.
6. Can be easily cast at job site which saves transportation cost.
7. It is easy to carve artificial stone.
8. It does not require any precaution regarding natural bed as there is no natural bed is present in artificial stones.
9. Artificial stone is free from defects as they are produced carefully.
10. It is relatively environment friendly.
8. Less costly than natural stone.
1. The texture is soft and easy to scratch.
2. Poor shrinkage performance
3. Extreme hardness sometimes worse.
4. Though it has certain temperature resistance, high temperature makes artificial stone tarnish.
