Abstract

The utility model relates to a building block of compound functional type immature soil of gradient structure comprises central cuboid and peripheral a plurality of annular cuboid, the center of building block is cuboid S, and the long wide of annular cuboid A in the cuboid S outside is respectively from outer m and the n of moving in central cuboid S's edge, the annular cuboid B's in the outside long wide edge for from annular cuboid A is outer again moves m millimeter and n millimeter, analogizes in proper order until annular cuboid N. Not only remain the advantage of traditional immature soil building materials but also has had higher intensity and stability, have light, antidetonation, insulate against heat, keep warm, excel in, water -resistance can be good etc. Characteristics, be a high performance building material.

Description

A kind of gradient-structure complex function type raw-soil building block

Technical field

This utility model relates to a kind of gradient-structure complex function type raw-soil building block, belongs to building material field.

Background technology

The good characteristics such as traditional raw soil building material has damping, ventilative, fire prevention, energy consumption is low, cost is low, but it also exists again the birth defects such as low, big, the poor water resistance of deformation of intensity, causing the building using tradition raw soil material, its antidetonation, water resistant and volume stability are all poor. Chinese scholars has carried out much research to the raw-soil is modified, such as, by filling cement, Calx etc. to improve intensity and the resistance to water etc. of raw soil material, but unsolved problem is always: the material modified addition content such as cement is few, then the drawbacks described above of raw soil material is improved inconspicuous; And material modified addition content is many, the intrinsic insulation of raw soil material, damping, pollution-free can lose again by the good characteristic such as back to nature.

Summary of the invention

In order to solve the problems referred to above, inventor developed a kind of raw-soil building block, the building block of this raw-soil not only remains the advantage of tradition raw soil building material but also has higher-strength and stability. The component of this building block presents graded laterally from zone line so that building block is integrally formed change functionally, has lightweight, antidetonation, heat insulation, insulation, a feature such as high-strength, water repelling property is good, is one high performance building materials.

The purpose of this utility model is in that to provide a kind of gradient-structure complex function type raw-soil building block.

This building block is multiple structure, is made up of center cuboid (S) and several annular cuboids peripheral; The center of building block is cuboid (S); Being annular cuboid (A) outside it, its length and width respectively move m and n from the edge of center cuboid (S); (A) the annular cuboid (B) in outside, its length and width are move m millimeter and n millimeter from the edge of annular cuboid (A); The like until N; The material of center cuboid (S) is 100% raw-soil, the material of annular cuboid (A) is 95～99% raw-soil and the mixture of 1～5% cement, from annular cuboid (A) to annular cuboid (N), raw-soil consumption successively decreases successively, cement consumption is incremented by successively, the cement incremental change of adjacent annular cuboid material is between 1～5%, and the raw-soil and cement quality sum are constant, the like until N; The consumption of cement is less than or equal to 20%.

In order to obtain better effect, the number of annular cuboid is be more than or equal to 3.

Advantage of the present utility model and feature:

1. the building block of this raw-soil makes raw-soil building block that graded structure in is integrally formed by the graded of the volume of material modified cement, makes goods obtain the composite performance of high-quality.

2. the building block of this raw-soil has higher strength and stability. Compared with the equally distributed modified raw soil building block of cement, this raw-soil building block cement amount used when reaching same intensity is greatly decreased, and improves the level of resources utilization, decreases environmental pollution; When cement mixing content is identical, then building block of the present invention has higher intensity.

3. the building block of this raw-soil had both had higher intensity and water-resistance, remain again tradition raw soil material insulation, damping, heat insulation, pollution-free can the performance such as back to nature, be that the desirable of tradition raw-soil wall material substitutes.

Detailed description of the invention

In order to be more fully understood that this utility model, illustrate this utility model is further described below in conjunction with accompanying drawing, but be not limiting as this utility model.

As shown in Figure 2,3, 4, putting into the toroidal membrane that can be drawn out of in mould, mould is divided into S, A, B, N tetra-lattice, the spacing 39mm between long side direction, adjacent separator, at short side direction, adjacent separator spacing is 19mm.

Preparing 1,2,3,4 four groups of slips, slurry 1 is the raw-soil after 100% dry grinding, adds cement from slurry 2 to slurry 4, the cement mixing content respectively raw-soil and the 5% of cement gross mass, 10% and 15%, the ratio of mud 0.3. Being poured into by slip 1 in center cuboid (S), slurry 2 is poured in annular cuboid (A), and slurry 3 is poured in annular cuboid (B), and slurry 4 is poured in annular cuboid (N); Filler extracts toroidal membrane out after having built, and is placed on vibration table by building block vibratory compaction molding together with mould, makes four partial fusion integral; Maintenance 48 hours, form removal under room temperature, light protected environment afterwards, continues room temperature lower seal maintenance 26 days in the cool, dry, obtains this utility model building block.

Test indicate that, the intensity of this utility model building block is identical far above cement consumption but be equally distributed modified cement raw-soil building block.

This building block had both had higher intensity and water-resistance, has again the features such as antidetonation, lightweight, insulation, water repelling property are good, is a kind of high performance building materials.
