Abstract
The invention discloses a papermaking waste residue aerated brick which is characterized by being prepared by the following raw materials by weight: 17-19 parts of papermaking waste residues, 9-13 parts of lime, 15-18 parts of river sand, 14-17 parts of apatite, 6-11 parts of cement, 0.3-0.5 part of aluminium powder, 0.2-0.4 part of sodium dodecanol sulfate, 0.1-0.4 part of methyl polyoxyethylene ether, 0.2-0.5 part of methyl methacrylate, 2-4 parts of milling steel fibers, 7-9 parts of sintering dry-method desulfurized fly ash, 0.15-0.3 part of gellan gum, 0.3-0.6 part of mannan, 1-3 parts of oleic acid, 2-5 parts of manganese dioxide, 0.1-0.3 part of symplocos paniculata, 0.2-0.6 part of chilli seeds, 3-6 parts of auxiliary agents, and a proper amount of water. According to the invention, papermaking waste residues are added into raw materials of aerated bricks, and other routine auxiliary agents are also added; the aerated bricks processed by appropriate technology have the characteristics of low cost, low unit weight, few cracks, high thermal insulation performance, good sound-absorbing effect, and high compressive strength. The circular economy effect of changing waste into valuables is realized, and pollution is reduced.
Description
technical field [0001] The invention relates to the technical field of aerated bricks, in particular to a papermaking waste slag aerated brick and a manufacturing method thereof. Background technique [0002] In recent years, with the acceleration of the industrialization process and the improvement of the level of urbanization, various environmental pressures and problems have also been brought about. Various solid wastes generated in the industrial production process and solid wastes caused by urban construction demolition and reconstruction have been troubled. In order to meet the living environment of residents, the present invention adds solid waste as a raw material to the aerated bricks, realizes waste recycling, reduces environmental pollution, and meets the strategic requirements of sustainable development. [0003] Aerated bricks are aerated concrete blocks produced by high-temperature autoclaved equipment. The aerated concrete block is a solid block made of cemen...
