Abstract
The invention discloses a preparation method of a compound functional raw soil building block having a gradient structure. The preparation method comprises the following steps: preparing a die composed of N regions and gradient cement-modified raw soil slurry, wherein the use amount of raw soil in the gradient cement-modified raw soil slurry for casting is progressively decreased in sequence, and the use amount of cement is progressively increased in sequence correspondingly, and the progressive increment of the cement of two adjacent groups is 1 to 5%; filling and casting the slurry to outside regions from middle regions in sequence, pulling clapboards out after the filling is finished, carrying out vibration or compression molding and then curing for 48 hours under room-temperature and dark conditions, dismantling the die, and continuing to cure in a sealing manner for 26 days under the same environment to obtain a building block product. The compound functional raw soil building block having the gradient structure, which is prepared by using the preparation method, not only reserves the advantages of a conventional raw soil building material, but also has relatively high strength and stability, has the characteristics of light weight, heat insulation, high strength, good water resistance and the like and is thus a high-performance building material.
Description
Technical field
The present invention relates to a kind of preparation method of gradient-structure complex function type raw-soil building block, belongs to building material field.
Background technology
Traditional raw soil building material has that damping, ventilative, fire prevention, energy consumption be low, the low good characteristics of cost, but it is existed again
The birth defects such as low intensity, the big, poor water resistance of deformation, cause the building using traditional raw soil material, its antidetonation, water resistant and volume
Stability is poor.Given this Chinese scholars opposite land reform has carried out many researchs, such as, by filling cement, Calx
Deng to improve the intensity and resistance to water etc. of raw soil material, but always unsolved problem is：The material modified addition content such as cement
Few, then the drawbacks described above of raw soil material improves unobvious；And material modified addition content is more, the intrinsic insulation of raw soil material, damping,
It is pollution-free can the good characteristic such as back to nature can lose again.
The content of the invention
In order to play the material modified optimization function to raw soil material performance to a greater extent, raw soil material is set to become a kind of
Not only traditional raw soil building material advantage had been retained but also there are the building materials of higher-strength and resistance to water, the present inventor had disclosed a kind of raw-soil building block
Preparation method, raw-soil building block prepared by this method is the features such as have lightweight, insulation, good high-strength, water repelling property.
It is an object of the invention to provide a kind of preparation method of gradient-structure complex function type raw-soil building block.
The purpose of the present invention is achieved through the following technical solutions, including step：
1) filling mould is prepared
With the rectangular spacer that can be extracted out, mould inside is divided into into N number of area；Adjacent clapboard spacing is equal；
2) N group modified cement raw-soil slips are prepared
The solid-state material of slip is made up of the raw-soil 80%~100% and cement 0~20%, from the 1st group to N groups, the raw-soil
Consumption successively decreases successively, and cement consumption is accordingly incremented by successively, keeps the raw-soil and cement consumption sum constant；From the 1st group to N groups,
The incremental change of the cement of two adjacent groups is the 1~5% of the raw-soil and cement gross mass；The ratio of water to material for preparing slip is 0.1~0.36；
3) to filling paste in mould
By step 2) prepare slip, by group number order from small to large, successively from the outside lateral areas filler in mesozone；Filler
After the completion of extract dividing plate out, using vibration or suppress by the way of molding；
4) by step 3) prepare molding raw-soil building block conserve 48 hours under the conditions of room temperature, lucifuge together with mould after tear open
Mould, continues sealed maintenance 26 days in equivalent environment, obtains gradient-structure complex function type raw-soil building block.
In order to realize more preferable effect, N values are more than or equal to 3.
Advantages of the present invention and feature：
1. the present invention provides a kind of new thinking for this environmentally friendly material of the significantly more efficient utilization raw-soil, with logical
Crossing the graded of material modified cement mixing content makes raw-soil building block form the graded in structure, makes product obtain high-quality
Composite performance.
2. the gradient-structure complex function type raw-soil building block that prepared by the present invention has higher strength and stability.With cement
Equally distributed modified raw soil building block is compared, and building block of the present invention cement amount used when identical intensity is reached is few, improves money
Source utilization ratio, reduces environmental pollution；In the case of cement mixing content identical, then building block of the present invention has higher intensity.
3. the building block that prepared by the present invention had both had higher intensity and water-resistance, and with preferable thermal and insulating performance,
It is the preferable replacement of traditional wall material, realizes structure-function integration.

Specific embodiment
For the present invention can be further appreciated that, hereby enumerate following examples and be further described, but be not intended to limit the present invention.
Embodiment 1
By releasing agents such as each face uniform application lubricating oil in the cast iron die for preparing inside, can extract out inside cast iron die
Toroidal membrane be divided into 4 lattice, in long side direction, the spacing of adjacent separator is 39mm, and in short side direction, adjacent separator spacing is
19mm, dividing plate both sides also equal smearing release agent.As shown in Figure 2.
Take cement and be dried the raw-soil after grinding, prepare four groups of modified cement raw soil material slips that numbering is 1,2,3,4：
From the 1st group to the 4th group, cement mixing content is respectively the 0% of the raw-soil and cement gross mass, and 5%, 10%, 15%；Mix process is for first
Mix will be added water after cement and the abundant mix of the raw-soil.The ratio of mud is 0.3.Slurry is taken by the order numbered from small to large of group simultaneously
Successively from filler in zone line laterally lattice, material is plugged and pounded with slotting tool simultaneously during filler close to ensure material filling
