pumice stone for plants

Pumice, also known as pumice stone or pumice stone, is a porous, light glassy acidic volcanic rock with a small bulk density (0.3-0.4). Its composition is equivalent to rhyolite. The pumice here is a glassy lava with dense pores formed by the condensation of molten magma during volcanic eruptions, and its pore volume accounts for more than 50% of the rock volume. The surface of pumice is rough, the bulk density of particles is 450kg/m3, and 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 for its many pores, light weight, and bulk density less than 1g/cm3, which can float on the water surface. It has the characteristics of light weight, high strength, acid and alkali resistance, corrosion resistance, no pollution, no radioactivity, etc. It is an ideal natural, green and environmental protection product.
