Embodiment 1

[0020] The present invention is a self-heat-insulating lightweight wallboard of fully recycled lightweight aggregate concrete, and the raw materials are weighed according to the following parts by weight:

[0021] Cementitious material 45, fully recycled lightweight aggregate 30, ecological fiber 0.1, physical foaming agent 2, foam stabilizer 0.1, water reducing agent 0.6, thickener 0.2, water 22.

[0022] After the raw materials of the lightweight aggregate concrete are prepared, the preparation method is as follows:

[0023] a. Put together the gelling materials, ecological fibers, and thickeners required for the ingredients and stir together. The stirring and mixing time is 5 to 8 minutes, and then follow the water, physical foaming agent, foam stabilizer, The water reducing agent is added in turn, and the stirring is continued for 4 to 8 minutes to obtain a slurry mixture;

[0024] b. Add fully recycled lightweight aggregate to the slurry mixture obtained in step a, and s...

Embodiment 2

[0026] The present invention is a self-heat-insulating lightweight wallboard of fully recycled lightweight aggregate concrete, and the raw materials are weighed according to the following parts by weight:

Abstract

The invention discloses a fully recycled lightweight aggregate concrete self-heat insulation lightweight wall panel and a preparation method. Fully recycled lightweight aggregate concrete is prepared from, by mass, 30-60 parts of cementing materials, 5-40 parts of fully recycled lightweight aggregates, 0.05-0.6 part of ecological fiber, 0.5-4 parts of physical foaming agent, 0.02-0.14 part of foam stabilizer, 0.1-0.8 part of water reducing agent, 0.03-0.3 part of thickening agent and 15-35 parts of water. The preparation method particularly comprises the following steps that the cementing materials, the ecological fiber and the thickening agent which are needed by blending are put together to be stirred and mixed for 5 min to 8 min, the water, the physical foaming agent, the foam stabilizer and the water reducing agent which are needed by blending are sequentially added into the mixture, stirring continuous to be conducted for 4 min to 8 min, and a slurry mixed material is obtained. The foam concrete has a more uniform and porous structure, holes are small and uniform and are not mutually connected, and therefore the waterproof, sound insulation and heat insulation effects are better than those of existing foam concrete.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a fully recycled lightweight aggregate concrete self-insulating lightweight wall panel and a preparation method. Background technique [0002] A large amount of municipal solid waste—construction waste—is produced across the country every year. If this problem can be effectively solved, it will bring huge social, environmental, and economic benefits. The recycling and utilization rate of general construction waste is low, and the level of classification and collection of construction waste is not high. Most of them can only be collected in a mixed manner. The technical level of construction waste treatment and resource utilization is lagging behind, so it is necessary to effectively collect construction waste. Crushing and screening to maximize reasonable classification and recycling. Construction waste contains a large amount of aerated blocks and lightweig...
