Abstract

The invention discloses a preparation method of an optical fiber-doped waste mud alkali-activated phosphorous slag geopolymer. The technical scheme comprises the steps of carrying out synergistic wet grinding on 90-200 parts of phosphorus slag and 50-100 parts of nickel slag according to a water-material ratio of 0.3-0.7 until the median particle size is 1-4 [mu]m to obtain slurry A; crushing the optical fiber waste mud, and sieving the crushed optical fiber waste mud through a 1.18 mm sieve to obtain optical fiber waste mud dry powder; carrying out wet grinding on the optical fiber dry powder according to a water-material ratio of 0.3-0.7 until the median particle size is 100-800nm to obtain slurry B; mixing and stirring 120 parts of the slurry A, 35 parts of the optical fiber waste mud dry powder, 5-50 parts of the slurry B, 10-40 parts of phosphogypsum, 20-50 parts of carbide slag, 20-50 parts of Na2CO3 and other materials, and preparing the optical fiber-doped waste mud alkali-activated phosphorous slag geopolymer through a mortar stirring machine according to the mortar ratio of 1: 3. The method is simple to operate, greatly reduces the production cost, solves the problems of solid waste stockpiling land occupation, environmental pollution and the like, and has high economic benefits and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of light-doped fiber waste mud alkali-activated phosphorus slag geopolymer. Background technique [0002] With the development of economy, environmental problems are becoming more and more serious. In the past 10 years, the output of yellow phosphorus has increased rapidly year by year. However, while producing yellow phosphorus, a large amount of industrial waste, namely phosphorus slag, will also be produced. The utilization rate of phosphorus slag is low, and it is stacked in the open air all year round, which not only occupies land, but also the phosphorus and fluorine in it are gradually dissolved by rainwater and seeped into the ground, which will pollute water sources, affect plant growth, and endanger human health. Every year, a lot of money and energy are spent on environmental pollution control and related social issues. ...
