The Pumice:
Mineral grains are creating cartridge style of volcanic activity. The advantage mineral Pumice than building materiel similar such as: dust, sand, less weight to zero, have rigidity degree up (about 7).the
colour materiel including: white or grey like to white or yellow. The mineral Pumice has different grains as ingredient to large pieces with a diameter of 100 mm. each of these measurements are used for
specific purposes. An example, extract the mineral Pumice as lenses with a diameter of 50 to 100 meters and a height of about 5 m under the layers of soil and rock. After, digging to chip by bulldozer
stripping the removal operations of the layers of rock and soil mineral Pumice is done. In the next step is takes place truck loading operation. The mineral Pumice is shipped Species by trucks from the
mine.
the kinds:
-sand Pumice: Because low weight than conventional sand (washed / river) in the baton building factory is used Block (wall/ceiling) and the building filling level.
-Lens Pumice: Because of very low size and weight is used to very light ceiling blocks in the building workshop.
- Buff Pumice: including the slope of the roof of the building and the floor level of consumption.
-cash and oval: like a pea are unfilled due to the larger size is less price.
Application:
it is used to the slope of the roof, the building blocks of style, mosaic and fill in the various levels of the building .
