Perlite

perlite concrete block and is preferred worldwide for the bottom ring beams of double walled cryogenic tanks to provide excellent thermal insulation and structural support to static and dynamic loads.Kelite perlite concrete blocks combine high compressive strength with a low thermal conductivity to meet critical requirements in terms of strength and thermal insulation. Kelite blocks are of standard grade or can be made as per customer requirements with respect to compressive strength and thermal conductivity by changing the mix-ratios.
