| 摘要 |
The composition materials are used as residual formworks for concrete and reinforced concrete walls in the construction of residential, public, administrative and agricultural buildings and for heat insulation, soundinsulation and making of motorway silencing structures. The operational qualities of the hardened material are similar to those of the conventional building materials: bricks, gas-concrete and foam-concrete and structural and insulation building tiles. The method for the preparation of the composition is simplified and takes place by a completely automatic prduction process. The properties of the finished product can be changed by the introduction of different components. The basic components of the composition are cement, wood and/or wastes of farm produce, sodium silicate, calcium chloride or a combination with calcium hydroxide, pearlite and water, and the quantitites of some of them can vary in wide boundaries. 3 claims
