Basalt frp reinforcement Basalt rebar Basalt fibre is a high performance non-metallic fibre made from basalt rock melted at high temperature Basalt FRP Rebar is an outstanding product for concrete reinforcement. It weighs 4 times less than steel rebar and its tensile strength is 3 times higher. Basalt FRP rebars are manufactured from basalt fibresRead More Jan 22, 2020 As a general rule, non-metallic minerals have low densities while metallic minerals have high densities. Most of the major rock-forming minerals in the Earths crust, like quartz, feldspar, and calcite, have very similar densities (around 2.6 to 3.0 g/cm 3). Some of the heaviest metallic minerals, like iridium and platinum, can have densities ...
