Stable molded body as fire protection and / or thermal insulation and lightweight board with such, manufacturing process and use thereof and building containing a stable molded body or a lightweight board.

摘要

A stable molded article for use as a thermal insulation and / or as a fire protection, made on the basis of expanded perlite as an essential component. The expanded perlite used is a closed-cell perlite, meaning that it consists of air-filled spheres of expanded, closed-cell silica sands. The pearlite beads have a compressive strength of at least 0.4 N / mm 2 and in the dry state, a bulk density of 50 to 400 grams / liter. The remainder of the molding consists of at least one binder. The invention further relates to a lightweight board with such a shaped body for use in construction, a method for producing a shaped body and a lightweight board, a use of a lightweight board and a building with a lightweight board or a molded body.
