1. raw material explanation
The materials for wall is mainly with discarded EPS, haydite (clay haydite, haydites of book structure, lytag) and loess-
It is aggregate that MES, which improves the extruding raw-soil,；Auxiliary material is flyash, quick lime, aeroge, sticky rice juice, cement, graphite scoria and careless muscle
(fiber).
Loess-MES improvement extruding the raw-soil is will to be derived from local loess original soil to handle using expansion method.Loess
Including detrital mineral and clay mineral, the former accounts for 70% or more.In detrital mineral, light mine of the density less than 2.90 is mainly contained
Object accounts for 90% or more, and at most containing quartz, feldspar is secondly, there are also some carbonate minerals (calcite, dolomites etc.) for light mineral.
Clay mineral ingredient is mainly hydromica, kaolinite and montmorillonite in loess.The presence of these mineral, make loess have absorption,
The characteristics such as expansion, contraction, influence the engineering properties of loess.Carbonate mineral plays cementation, makes loess in natural structure
In the case of particle in aggregate exist.Therefore, the present invention using loess as it has been carried out when wall aggregate grind and life is added
Lime.Quick lime is added when loess is as wall aggregate, in the lime white that (realizing in compacting) is formed after quick lime curing, stone
Grey particle forms calcium hydroxide colloform texture, and particle is superfine (partial size is about 1 μm), and specific surface area is very big (up to 10~30m2/ g),
There is stronger adsorption capacity on its surface.
Haydite has excellent performance, and if density is low, keeps the temperature, heat-insulated, fire resistance, shock resistance are good, and water absorption rate is low, freeze proof
Property, durability, impervious good and anticorrosive (acid, alkali) the advantages that.Particularly because of haydite density is small, internal porous, form, at
It is point more uniform, and have some strength and robustness, thus there are the function such as light, corrosion-resistant, freeze proof, antidetonation and good insulating
