Mineral shell is one of the most widely used lightweight materials in Iran's construction and green space industry. There are two kinds of high -end types in the Iranian market: White Sheet , often obtained from pomegranate mines in Kerman or Bostanabad in Tabriz, and Black Poké (Scoria) which is usually extracted from Kerman or Qorveh Sanandaj areas. In this article, we thoroughly examine the differences, applications, sales tips and selection criteria.
Geology
- White Pumice (Pumice) : Light and highly porous silicate volcanic glass.
- SCORIA Black Shell : Ironini Basalti Stone with coarse and coarse -grained and dark drillers
Technical and practical comparison
Why is white sheet more suitable for lightweight concrete?
White sheet due to high porosity and low density increases the volume of air in the mixture and reduces the final weight of the concrete. Pumice is one of the best choices in the production of autoclave (AAC) and roof concrete.
Important Tips When Buying Poke
Price and shipping
The price of the shell is influenced by the type (pumice or scoring), grainness, mine distance to delivery location and loading. For construction customers, the sale is usually made according to the cubic meter and for the carriage of the fare to carry the truck.
Frequently Asked Questions (FAQ)
White shell is better or black?
is better for insulation and white shell concrete; Black shell is more suitable for drainage and applications that require more strength.
How is the price of the sheet calculated?
usually based on cubic meter for pumice and tone for Scoria; But the agreement with the seller is decisive.
How to prepare the shell for concrete?
Soak the white shell for a few hours (pre -water) to fill the water inside the pores and prevent the absorption of cement water.
Conclusion and contact
Choosing the right shell depends on the project needs and economic conditions. If you are looking to lose weight and thermal insulation, White shell (pumice) is a great option. Consider Black Sheet (Scoria) for more stressful or affordable applications in high volume.
