Problems solved by technology

However, it is worth noting that fluorogypsum, as a kind of industrial waste, has been piled up in large quantities for a long time, which not only increases the discharge burden of enterprises, but also occupies a large area of ​​land resources. At the same time, the acidic substances contained in fluorogypsum will be Under the erosion of rainwater, it seeps into groundwater and surface river water, seriously pollutes the surrounding environment, and threatens human health

Abstract

The invention discloses a fluorogypsum-based multi-component composite light high-strength wall material. The fluorogypsum-based multi-component composite light high-strength wall material comprises,by weight, 1 part of industrial fluorogypsum, 0.03-0.05 parts of cement, 0.1-0.3 parts of fly ash, 0.01-0.05 parts of an activator, 0.001-0.01 parts of a water reducing agent, 0.1-0.2 parts of waste rubber particles, 0.1-0.2 parts of ceramic particles, 0.001-0.005 parts of a foaming agent and 0.4-0.8 parts of water. Through the gelling property of fluorogypsum and the sound absorbing property of waste rubber, the light high-strength wall material with good heat insulation and sound absorption properties is produced. The preparation method realizes efficient utilization of fluorogypsum, consumes a large number of industrial wastes such as waste and old rubber tires and fly ash and has good environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of building material production, and in particular relates to a fluorogypsum-based multi-component composite light-weight high-strength wall material and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the change of social concepts, people pay more and more attention to the problem of environmental pollution. How to effectively and rationally reuse waste resources has become a new problem given by the times, and it is also necessary for my country's sustainable development. problem to be solved. [0003] Fluorogypsum is a by-product of producing hydrogen fluoride from sulfuric acid and fluorspar. The main component is anhydrous calcium sulfate, which can be used to make building materials. Increased, fluorine gypsum emissions are also increasing. However, it is worth noting that fluorogypsum, as a kind of industrial waste, has been piled up in large ...
