Description
Technical field
The invention belongs to civil construction material technology field, relate to a kind of soil-solidified-agent, be particularly related to the hydraulicity green gelling material GMBER (A Green Materrialbecoming Earth into Rock), i.e. novel green soil-solidified-agent that a kind of civil construction project is used.
Background technology
At present, the colored gelatinous material that uses in civil construction project mainly is a colored portland cement, and this colored gelatinous material is to make aggregate with the sandstone material, and is bad to the clay solidifying effect, also high to water quality requirement.When making aggregate, when making gelling material mix concrete material,, except that particular requirement, then to the earth in the sandstone be cleaned up as far as possible sandstone material and water quality in order not influence concrete performance with colored portland cement with sandstone.This not only wastes time and energy, and in no sandstone material or the bad area of water quality, the color concrete construction costs will significantly improve.
For loess plateau and vast no sandstone material area, seek a kind of high-strength, water-fast, adaptability is strong, both can be the same with cement be aggregate with sand, stone chip, there is not particular requirement to mixing and stirring water quality again, and can make full use of local water and soil resources, particularly can solidify the colored gelatinous material of the argillous hydraulicity-colored soil-solidified-agent, be that reality is badly in need of.Though the relevant report of soil-solidified-agent is also arranged, existing solidifying agent in use often brings, problems such as anti-freezing property poor, cost height low such as intensity, aspect colored soil-solidified-agent development, and weak link especially.Therefore, the research of new soil-solidified-agent is that the insider extremely pays close attention to.
Summary of the invention
The objective of the invention is to, providing a kind of is main ingredient based on slag and aluminium silicate mineral, add that an amount of activity excitant is mixed and made into through the compounded superfine active powder of modern crafts, low price, can be in vast no sandstone material area, reacting with all kinds of soil becomes firm persistent formed parts, is used for the novel green soil-solidified-agent of facility signs such as road, current collecting field.Roll by mixing and stirring with soil by a certain percentage, push have resistance to compression after closely knit, antiseepage, performance such as freeze proof.Not only have the natural soil of utilization, gather materials on the spot, reduce the sandstone freight volume, non-environmental-pollution is saved advantages such as construction costs, but also can be utilized or handle some common industrial waste such as flyash, coal petrography stone, materials such as slag, slag are so it also has the characteristics of economy, environmental protection.
In order to realize above-mentioned task, the present invention takes following technical solution:
