Lightweight concrete is a collective term for different types of concrete which are all characterized by a low specific weight. The reduced density is achieved by adding specific ingredients to the mixture or by means of special production techniques, resulting in a weight decrease from 2.000 or 2.500 kg/m³ for 'ordinary' concrete to approx. 500 […]Web

pumice. Pumice aggregates have specific gravities of 1.68, 1.18, 0.98, and 0.92 for sizes 0-2, 2-4, 4-8, and 8-16, respectively. To ensure that the qualities of the pumice aggregate do not alter before production stages, it should be kept in closed storage rooms; the water absorption rate of pumice (lightweight aggregates) is quite high.Web

The light pumice, due to the higher number of pores, is lighter than lava rocks. Pumice porous - up to 85% -, has a low dry bulk density, which in ours, is between 350-500 kg/m³, and therefore can float on water. Our pumice has a high degree of whiteness, and here the higher the pore content and the smaller the bubble size, the lighter the pumice.Web
