Abstract

The invention provides a wall material composite material, and belongs to the technical field of building materials. The wall material composite material comprises the following components in percentage by mass: 0.1%-6% of ordinary Portland cement, 0.1%-12% of sulphoaluminate cement, 40%-70% of semi-hydrated gypsum, 5%-15% of anhydrous gypsum, 15%-30% of a filling aggregate, 1%-3% of a water reducing agent, 0.2%-1.2% of a reinforcing agent, 0.1%-0.8% of a water repellent and 0.1%-0.3% of a thickening agent. The wall material composite material prepared by the invention has the characteristicsof controllable setting and hardening time, excellent mechanical properties, high early strength and continuously increased later strength.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite wall material. Background technique [0002] As a green building material, wall material has a series of advantages such as light weight, sound insulation, and heat preservation. However, the wall material production plant occupies a large area and the production cost is high; the raw material components used in the product are complex, and the product quality fluctuates greatly; the product condensation The time is long, the early strength is low, and the production efficiency is seriously affected. These factors limit the large-scale promotion of wall materials. [0003] CN107129205B discloses a wall material and its preparation method, wherein the wall material is mainly composed of cement, polyethylene glycol phase change heat storage particles, porous silica, foaming agent, fly ash, shrinkage reducing agent and modifier The mass ratio is (20-30):(10-2...
