Abstract

The invention discloses a modified ecological fiber reinforced recycled aggregate lightweight wall material and a preparation method. The modified ecological fiber reinforced recycled aggregate lightweight wall material comprises the following components in parts by mass: 15-36 parts of Sorel cement, 5-15 parts of ground granulated blast furnace slag, 10-25 parts of ceramsite, 12-40 parts of recycled lightweight aggregate, 8-20 parts of pottery sand, 0.1-0.6 part of modified ecological fibers, 0.1-2 parts of foaming agents, 0.2-1.0 part of thickening agent and 10-30 parts of water. The preparation method comprises the steps of putting the Sorel cement, the ground granulated blast furnace slag, the modified ecological fibers and the thickening agent, which are required for preparation, together and stirring the materials for 8-15 minutes, then adding water and the foaming agents, which are required for preparation, to the mixture in sequence and further stirring the materials for 10-15 minutes, thus obtaining a slurry mixture. The lightweight wall material and the preparation method have the beneficial effects that the ecological fibers have good tensile deformation resistance and are lighter, so the foam concrete has toughness; China has abundant ecological plant resources, thus saving plenty of resources and being beneficial to the human living environment.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a recycled aggregate lightweight wall material reinforced with modified ecological fibers and a preparation method thereof. Background technique [0002] In the Twelfth Five-Year Plan, saving energy and reducing consumption is an extremely important task. The energy consumption of the construction industry accounts for 40%-50% of the total energy consumption of the whole society. During the "Eleventh Five-Year Plan" period, 4-5 billion square meters of buildings will be built in Chinese cities and towns. New buildings will strictly implement mandatory energy-saving standards. Four municipalities directly under the Central Government will implement 65% energy-saving standards, and by the end of the 12th Five-Year Plan period, 65% energy-saving standards will be implemented nationwide. Lightweight wall materials are undoubtedly in line with this development...
