Abstract
The invention discloses a BMBER (A Back Material Becoming Earth into Rock); the BMBER comprises raw materials with the following weight portions: 75 percent to 80 percent of cementing material, 2 percent to 4 percent of iron oxide black, 2 percent to 5 percent of slag or slag mixture, 1 percent to 1.5 percent of surfactant, and 12 percent to 15 percent of alkaline catalyst; the total amount of the above weight percentage is 100 percent; the moisture content of each raw material is less than 2 percent; the mixed raw materials are milled to a Brinell ratio surface area of 400 to 900m<2>/kg; the iron oxide black and the above other compositions guarantee that the basic structural cell of the earth does not disperse and phase interfaces are contacted closely, and synchronously exert the potential activity of the earth aluminate minerals so that the interface thereof forms firm polycrystalline black clay aggregates so as to improve the contact essence of the earth particle phase interfaces and generate higher strength and water stability. Under the same condition, the strength of the solidified soils in the same age period can be increased by more than 100 percent, and impermeability, frost resistance, chemical resistance and color retention property are greatly improved.
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 black gelling material BMBER (A Back MaterrialBecoming Earth into Rock) that a kind of civil construction project is used, promptly novel black soil curing agent.
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, a kind of novel black soil curing agent BMBER is provided (A BackMaterrial Becoming Earth into Rock), it is based on slag and aluminium silicate mineral is a main ingredient, add the superfine active powder that an amount of active catalyst is mixed and made into, its raw material is easy to get, and low price can be in vast no sandstone material area, reacting with all kinds of soil becomes firm persistent formed parts, can be widely used in 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 wastes, as materials such as flyash, coal petrography stone, slag, slags, so it also has the characteristics of economy, environmental protection.
In order to realize above-mentioned task, the present invention takes following technical solution:
