Description
Technical field
The invention belongs to building material technical field, a kind of more particularly to raw-soil suitable for raw-soil building block is plastered cohesive material
Material and preparation method thereof.
Background technology
The raw-soil refers to original state earthen materia that is not fired and only passing through simple closely knit processing, from human society formed with
Come, the raw-soil is always most important construction material, the Chinese earth building history at least more than 6000 year, many ancient
Earth building preserve so far, turn into the witness and history rarity of Chinese civilization.
Still there is about 1/3 inhabitants live in the whole world in earth building, and China rural area is so far there are people lives in more than 100,000,000
In various types of earth buildings.China is vast in territory, and the vast rural areas exist in weather, resource, economy, traffic etc.
Greatest differences and diversity, be to push forward rustic home comprehensively to build the ultimate challenge that is faced of sustainable development all the time.In skill
In art aspect, based on local resource and architectural tradition, the countryside characteristic building materials and suitability building technology of exploiting economy environmental protection, it is
Tackle this and challenge one of maximally effective approach.In this context, raw soil material, as current ecological cost performance highest, and gather around
There is the traditional construction material of extensive and deep application foundation, show important optimizing research value and application potentiality.
Traditional raw soil material is compared with cement-based material, and the performance such as its intensity, water resistance is obvious poor；But raw-soil material
Material has the characteristics that reusable edible, convenient material drawing, environment compatibility and thermal property are good, cheap, is typical life
State type construction material.So if modern industrial technology can be utilized to improve ancient raw soil material, obtain it higher strong
Degree and good durability, it is possible to the raw-soil is turned into the important construction material of the vast rural areas, it is also possible to make traditional raw-soil
Building is radiated vigour again.
The domestic research for raw soil material mainly using the natural raw-soil as main material, addition string, cement and its
His additive adds compressing raw-soil materials for wall after water mix, such as raw-soil building block, simple production process, can be recycled simultaneously
Be easy to degraded, thermal and insulating performance it is good, it is cheap, kept for the features such as traditional raw-soil wall mechanism and texture, be a kind of be applicable
In country building and the green materials for wall of tourism building, can be not only used for substituting traditional rammed earth, sun-dried mud brick, it is also alternative solid
Materials for wall of the clay brick as country building.Building block building has as a kind of construction style of suitable China's national situation
The superiority such as anti-seismic performance is more prominent, construction technology is convenient, construction costs is low, undoubtedly there is wide prospect.
But it is typically more using common motar with the supporting plastering material of raw-soil building block at present, due to commonly plastering
Mortar performance differs larger with raw-soil building block physical and mechanical property, therefore certainly exists many drawbacks in actual applications, and unfavorable
Cycling and reutilization after the soil body is discarded.Therefore, the conventional cement mortar commonly used at present in building trade can not be applied well
Into raw-soil building block.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of raw soil material method of modifying and utilization to be modified
The method that the raw-soil prepares binding material of plastering afterwards, physical and mechanical property, crack resistance and the durability of raw soil material, tool can be improved
The characteristics of gathering materials on the spot, be simple and easy, be economic and environment-friendly.
