Preparation method of green energy-saving foam concrete

Abstract

The invention relates to foam concrete.The foam concrete comprises main materials and auxiliary materials, to be more specific, 30-40 parts of industrial waste mixture of vesuvianite, perlite and the like serving as the first main materials, 15-30 parts of high-strength cement, 5-10 parts of light calcium carbonate and 5-10 parts of quicklime serving as the second main materials, 0.5-2 parts of polyester staple fibers serving as the first auxiliary materials, 1-5 parts of water reducing agent, 1-5 parts of foam stabilizer, 1-5 parts of moisture repellent, 1-5 parts of early strength agent and 0-5 parts of antifreezing solution serving as the second auxiliary materials, 1-5 parts of PVC (polyvinyl chloride) resin, 1-5 parts of polyvinyl alcohol and 1-5 parts of bone glue serving as the third auxiliary materials, as well as 1-5 parts of foamer and 1-5 parts of accelerator serving as the fourth auxiliary materials.The preparation method includes crushing the first main materials, mixing the third auxiliary materials with water in the ratio of 1:2-5, adopting a blender for dry blending of the first main materials, the second main materials and the first auxiliary materials, respectively pouring in aqueous solutions of the second auxiliary materials and the third auxiliary materials, mixing while stirring prior to adding in the foamer and the accelerator with stirring, and using a bubble machine for bubbling, discharging and entering a mould.

Description

Technical field

[0001] The invention relates to a method for preparing building materials, in particular, to a method for preparing foam concrete with multiple advantages of energy saving, green and environmental protection. Background technique

[0002] Concrete usually refers to the use of cement as a cementitious material, sand and stone as aggregates, mixed with water in a certain proportion, and mixed. Because of the wide range of raw materials, low price and simple production process, concrete has a wide range of applications. It is not only used in various civil engineering and construction, but also widely used in shipbuilding, machinery industry, marine development, geothermal engineering, etc. It can be seen that concrete can play an important role in various constructions. Due to the adverse impact of concrete on the environment during use, foam concrete has been used in some daily production.

[0003] The existing foamed concrete is also called foamed cement, lightwei...
