Properties of mineral pumice
Specific weight Low (0.5 to 7/•) so that it floats on water. Sound, heat and cold insulation. Fire resistant; So that up to 760 degrees Celsius, there is no change in its volume and shape. The melting point of this mineral is 1342 degrees Celsius.
Strength; Concrete and masonry made of mineral pumice have high durability compared to weight.
Usages:
•- Pumice sand: due to its very low weight compared to ordinary sand (washed/river) in concrete making works, block making (wall/ceiling) and covering the surface of construction pipes and... It is used.
•-Lens pumice: Due to its very small size and weight, it is used in the production workshops of very light roof blocks. Leveling the floor of the floors and...- Hazelnuts and almonds: It can be used like pea pumice and because of its larger size, it has a lower price. And...it is used.
• As sound insulation for engine houses and noisy places. • For agricultural use in low-water areas due to the property of absorbing and retaining water (from small particles to 30 mm grains) dams, wharves and bridges (powder-like particles) It is noteworthy that concrete made from mineral pumice, in addition to its lightness, also has great strength and resistance against various environmental factors
• The mixture of this material With slaked lime, it forms a kind of natural cement that hardens under water and outside. In the cement industry, this mineral can be used as one of the important components of cement. 40% Portland pozzolanic cement. The mixing percentage is more than 40% pozzolanic cement. ................................................ ...................................

Scria (pebble)
It is the oldest light grain used This stone was created by the entry of volcanic melt into water reservoirs such as seas and lakes and rapid cooling. The color of these light grains is black, light gray and dark brown. Due to the rapid cooling of the molten volcanic material, there are relatively large bubbles in these aggregates, which are sometimes connected and extended to the surface of the aggregate. The apparent dry specific weight of these light grains is around 500 to 800 kg/m3 (according to granulation). Chemical analysis. The presence of silica,
