Abstract

The invention discloses immature-soil-based aerated heat-insulating building block ingredients which include, by weight, 62.8-78.5% of immature soil, 10-15% of sulfur aluminum cement, 10-20% parts beta gypsum, 0.6-0.9% of NaOH, 0.7-0.9% of aluminum powder and 0.2-0.4% of CaO. A novel wall material is developed, no waste is generated, energy consumption is low, CO2 emission is low, and indoor air quality is excellent. Heat conducting coefficient is smaller than 0.08W / (k m), and heat insulativity is high. A lot of immature soil materials are utilized, and only a few of modifying material is used, so that production cost is low, the novel wall material is an energy-saving environment-friendly material, and requirements on environment-friendly buildings are met; material source is extensive, and materials can be obtained locally, so that production cost and the transport cost are lowered.

Description

technical field [0001] The invention relates to a raw soil-based aerated thermal insulation block ingredient and a preparation method of the block, belonging to the technical field of building materials. Background technique [0002] With sustainable development and low-carbon economy deeply rooted in the hearts of the people, the development of new wall insulation materials will become an inevitable choice for the development of the building materials industry. Although traditional organic thermal insulation materials have the advantages of good thermal insulation and strong processability, they also have disadvantages such as easy cracking, poor durability, and flammability. [0003] At present, research on the modification of raw soil materials has made some progress. However, there are few reports on the research on raw earth-based aerated thermal insulation blocks. Contents of the invention [0004] The purpose of the present invention is to provide a raw soil-based...
