Abstract

The invention discloses a novel porous brick and a preparation method thereof. Raw materials (in parts by weight) comprise 20 parts of ceramsite, 10 parts of Tauscha, 40 parts of recycled fine aggregates, 20 parts of fly ash, 5 parts of montmorillonite, 8 parts of plant straw powder, 2 parts of lignocellulose, 1 part of coal gangue, 0.1 part of a water reducer and 0.2 part of a foaming agent, wherein the recycled fine aggregates are obtained by directly crushing and filtering abandoned concrete, and the particle sizes of the recycled fine aggregates are less than 5 mm. The porous brick prepared by the invention adopts the abandoned concrete to save resources and solve the problem of secondary pollution on the environment caused by the abandoned concrete; the strength and ductility of a porous brick masonry formed by pressing are improved, and the seismic capacity of the porous brick formed by pressing is enhanced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel porous brick and a preparation method thereof. Background technique [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. As one of the house insulation materials, the porous brick is more and more popular because of its heat preservation, sound insulation, fire prevention, and strength superior to traditional insulation materials. In order to meet the needs of building bricks, pressed porous bricks have emerged as a new energy-saving, land-saving, high-strength and green wall material, and are a good substitute for clay brick products. There are many holes in the press-molded porous brick, which can reduce the amount of materials used, and have better heat and sound insulation effects. In...
