Pumice, also known as pumice or pumice, is a porous and light vitreous acidic volcanic volcanic rock with a small bulk density (0.3-0.4). Its composition is equivalent to rhyolite. The pumice here is a vitreous lava with dense pores formed by the condensation of molten magma with volcanic eruption, and its pore volume accounts for more than 50% of the volume of the rock. The surface of pumice is rough, the bulk density of particles is 450kg/m3, the bulk density is about 250kg/m3, the porosity of natural pumice is 71.8-81%, and the water absorption rate is 50-60%. It is named because it has many pores, light weight, and a bulk density of less than 1g/cm3, and can float on the water surface. It is characterized by light weight, high strength, acid and alkali resistance, corrosion resistance, no pollution, no radioactivity, etc. It is an ideal natural, green and environmentally friendly product.
