Abstract

The invention discloses an ardealite concrete extrusion partition board and a preparation method thereof. The ardealite concrete extrusion partition board is prepared from, by weight, 350-450 parts of cement, 350-450 parts of modified ardealite, 150-300 parts of river sand, 2-4 parts of polypropylene fiber, 3-5 parts of plant fiber, 8-10 parts of a water retaining agent and 230-250 parts of tap water. In this way, the ardealite concrete extrusion partition board has the advantages that energy is saved, no pollution is caused, different wastes can be brought into full play, utilization of wastes is improved, a large number of natural mineral resources are saved, environment is protected, waste materials are recycled, and the nation and the people are benefited.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a phosphogypsum concrete extruded partition wall board and a preparation method thereof. Background technique [0002] At present, there are various types of partition boards used in the market, and according to research, there are the following disadvantages: [0003] 1. Under the influence of natural environmental factors such as wind and sun, rain, freeze-thaw, etc. for a long time, the concrete partition wall and fair-faced concrete partition wall will appear whitening, alkali return, shrinkage cracks and mildew on a large area of ​​the wall And so on. [0004] 2. After the partition board is installed, a layer of oxide film will be formed on the surface of the board body. After the board body is painted, the paint layer will turn yellow and fall off easily; [0005] 3. The expansion and contraction rate of the partition board is large. After installation, there ...
