Mixture for producing building elements and process for producing the building elements

摘要

A mixture for the production of construction elements made of 750g-1250g cement, 750g -1250g dewatered pulp made from crushed and moistened paper and/or paperboard and/or cardboard and/or cellulose and/or plant material and 250-750g plaster. Said mixture contains 15-75 % by mass synthetic material and up to 15g colourants. The products from the mixture for the production of said construction elements are produced in such a way that the crushed moistened paper and/or paperboard and/or cardboard and/or cellulose and/or plant material is mixed to form a pulp which is dewatered and which is mixed with the cement and plaster, whereupon synthetic material is mixed and the pulp is then pressed in a mould at a pressure of 1.5-30 Mpa and left to mature in the air. The crushed moistened paper and/or paperboard and/or cardboard and/or cellulose and/or plant material is mixed to form pulp which is dewatered and mixed with the cement and plaster, whereupon synthetic material is added, the colourant is added and the pulp is then pressed in a mould at a pressure of 1.5-30 Mpa and left to mature in air. The crushed moistened paper and/or paperboard and/or cardboard and/or cellulose and/or plant material is mixed to form pulp which is dewatered and mixed with the cement and plaster, whereupon synthetic material and the colourant are added, the pulp is then pressed in a mould at a pressure of 1.5-30 Mpa and left to mature in air. The matured products are surface treated.
