Abstract

The invention belongs to the technical field of lightweight bricks and in particular relates to a lightweight brick manufactured by utilizing paper mill sludge and a manufacturing method thereof. The lightweight brick is manufactured from the following raw materials in parts by weight: 50-60 parts of paper mill sludge, 30-50 parts of construction wastes, 40-60 parts of potassium feldspar powder, 10-40 parts of fly ash and 40-60 parts of cement. The adopted paper mill sludge can be used directly without dehydration and drying, therefore the energy is saved, the cost is low and the production efficiency is high; the manufactured lightweight brick has low shrinkage, low volume weight, high compression strength and good thermal insulation property; the compression strength is as high as 60-120MPa; the lightweight brick has better physical and mechanical properties than the common natural stones; and plenty of construction wastes, paper mill sludge and fly ash are used, therefore the manufactured product has low cost and high economic benefit, and the method not only can be used for turning wastes into wealth, but also is beneficial to reduction of environmental pollution and has obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of lightweight bricks, in particular to a lightweight brick made from papermaking sludge and a manufacturing method thereof. Background technique [0002] Most of the bricks used in the construction industry are made of clay and other auxiliary materials evenly mixed and then fired through a briquetting machine. This brick is relatively heavy when building a wall, and it is laborious to build a wall. At the same time, the wall made of this brick is soundproof, The heat preservation and shockproof effects are poor, and the shockproof performance is low. At the same time, because a large amount of clay is needed to make raw materials, natural resources and ecological balance are destroyed. [0003] With the development of science and technology, some new furnace ashes and ceramsite bricks have appeared. For example, Chinese invention patent application 200910027910.8 discloses a light-weight energy-saving ins...
