Insulating building materials produced by mixing non

摘要

Building materials with sound and heat insulating properties produced by mixing a non-globular material with particle size between 0.5-50 mm, such as sand, gravel, pumice, brick dust, perlite, sawdust or synthetic granulates or wastes, with a suitable binder, such as polyesters, epoxy resins, etc. pouring the mass into a mould and curing the binder in a suitable manner. Material is as strong as concrete; good adhesion; more easily manufactured than similar concrete article; no water required; low density.
