Abstract
The invention relates to a lightweight substance molded body made of a lightweight aggregate and a sintering auxiliary agent, wherein said molded body consist of a sintering product containing 60-95 wt. % lightweight aggregate with 40-5 wt. % water-soluble alkali silicate.
Claims17
A molded body from a lightweight substance formed from a lightweight aggregate and a sintering auxiliary, comprising:
- a sintered product obtained by mixing a lightweight substance of 80 to 93 wt % of a lightweight aggregate, selected from the group consisting of expanded glass, scrap glass, and their mixtures with 20 to 7 wt % of an aqueous alkali silicate solution, where the lightweight aggregate is bonded in a network structure exclusively at the contact sites to obtain its essential properties, wherein the molded body has a dry bulk density and that dry bulk density lies in the range from 150 to 750 kg/m3.
