Abstract

The invention discloses an environment-friendly porous ceramic tile and a preparation method thereof, belonging to the technical fields of waste treatment and building materials. The porous ceramic tile is prepared from the following raw materials in parts by mass: 35-45 parts of lake sludge, 30-40 parts of clamshells and 15-30 parts of fallen plant leaves. The preparation method comprises the following specific steps: mixing the lake sludge and the fallen plant leaves according to a certain ratio and carrying out uniform stirring to obtain a sludge mixture; crushing the clamshells, carrying out ball milling to obtain powder, weighing the clamshell powder according to a certain ratio, adding the clamshell powder into sludge slurry, and carrying out uniform stirring to obtain mixed slurry;carrying out sealed aging at room temperature for 12 hours, putting the aged mixed slurry into a brick making mold, and carrying out compression molding to obtain a green brick blank; putting the green brick blank into a kiln, carrying out preheating for a period of time, and conducting sintering according to a certain temperature schedule; and then performing air-cooling to room temperature alongwith the furnace so as to obtain the porous ceramic tile with an apparent density of 0.52-0.64 g / cm<3>, a porosity of 66.0-78.4% and compressive strength of 7.8-10.5 MPa. According to the invention,recycling of waste such as the lake sludge, the clamshells and the fallen plant leaves is achieved, environmental pollution is reduced, and the production cost of building materials is reduced.

Description

technical field [0001] The invention belongs to the technical field of waste treatment and building materials, and in particular relates to an environment-friendly porous ceramic brick and a preparation method thereof. Background technique [0002] There are many freshwater lakes in the middle and lower reaches of the Yangtze River in my country. The natural soft soil at the bottom of the lake has been deposited in the water for a long time, and the aquatic plants have multiplied and rotted, and they are decomposed under the chemical action of microorganisms to produce muddy mud with super high water content. The organic matter in the mud It decomposes under anoxic conditions and becomes acidic, which inhibits the growth of fish, and once the silt at the bottom of the lake accumulates to a certain extent, it will cause excessive oxygen consumption of organic matter, making the lower water in a state of anoxic for a long time, thus causing fish to grow in summer and autumn. Oxy...
