Abstract

The invention relates to a method for producing a light-weight wall material by using papermaking white clay. The method comprises the steps of preparing the following components in percentage by mass: 60-70% of papermaking white clay, 5-10% of zirconium-silicate slag, 20-30% of Portland cement and 1-5% of an enhanced water-releasing agent and mixing uniformly, preparing into concrete slurry having a required flowability, curing and molding, wherein the enhanced water-releasing agent is a mixed solution prepared by dissolving 4-5 parts of sodium sulfate, 7-8 parts of triethanolamine, 15-18 parts of saccharide sodium, 25-30 parts of sodium methyl sulfonate and 40-45 parts of calcium lignin sulfonate in water. The wall material prepared by the method disclosed by the invention has the advantages of good compressive strength, good heat insulation property, low density and light self-weight.

Description

technical field [0001] The invention relates to a method for producing light-weight wall materials with papermaking white mud, and belongs to the technical fields of waste utilization and building materials. Background technique [0002] According to the data of China Paper Association, as of the end of 2012, my country's paper and cardboard production and consumption have surpassed the United States for three consecutive years, ranking first in the world, reaching 99.3 million tons, and paper production and consumption accounted for 23.3% of the world's total. % and 23.1%. [0003] Shandong Province is a major paper-making province, with an output of 17.1 million tons in 2012, accounting for 17% of the country's total output, ranking first in the country for 18 consecutive years. While vigorously developing paper-making enterprises in our province, the water pollution problem in the paper-making industry has been improved to a certain extent, but white mud pollution will in...
