Abstract
The invention discloses a composite soil stabilizer. The composite soil stabilizer is characterized by comprising a powder material and liquid material in a weight ratio of 9:1, wherein the powder material comprises quicklime, cement, pulverized coal ash, calcined phosphogypsum and composite additive at a weigh ratio of 2:1:3:0.33:0.07; and the liquid material comprises modified acrylic acid emulsion, VAE (vinyl acetate ethylene) emulsion and antifoaming agent at a weight ratio of 3:2:0.03. The composite soil stabilizer can be used for stabilizing using natural soil, and raw materials are obtained locally, thereby reducing sandstone transport volume and saving costs of construction projects.
Description
Technical field
The present invention relates to soil-solidified-agent, especially the compound soil-solidified-agent of organic-inorganic.
Background technology
In the road use, because the variation of natural condition such as weather, many physics and chemical transformation take place in soil, cause road basement material performance loss of stability, and subgrade moisture content increases, and plastic limit of soil changes, and the road supporting capacity reduces.Perhaps roadbed generation frost boiling and soil layer are aging, have a strong impact on transportation safety.For this reason, in the process of repairing the roads, how to utilize cheap soil-solidified-agent that soil is cured the problem that the person that is the constructing road must consider.
The curing mechanism of soil-solidified-agent is that multiple physics and chemical reaction take place when contacting with the soil fine particle, make the interface form firm many crystalline aggregates, thereby changed the essence of granular boundary contact, soil-solidified-agent commonly used has following several: the cement class; The lime class; With cement, lime mixed reinforcement; Reinforce with lime, flyash, a small amount of admixture; Reinforce with other solidifying agent.Above material respectively has relative merits to the reinforcement effect of roadbed, as cement solidification soil good mechanical performance and plate body are arranged, early strength is higher, but, cement solidification soil easily produces the crack, and influences the stability of surface layer in temperature, when humidity changes, when the fine particle content height, when cement consumption is big, it is even more serious to ftracture.The lime solidified earth has the good mechanical performance, but its early strength is low and water stability is relatively poor.Also there is the shortcoming of class limy solidified earth in lime industrial residue solidified earth.
Above material respectively has relative merits to the reinforcement effect of roadbed, and still, their general constructions are trouble comparatively, and engineering cost is higher.Therefore, need exploitation a kind of applied widely, effect is obvious, and construction is simple, soil curing agent with low cost.
Summary of the invention
The objective of the invention is to overcome the method for existing soil-solidified-agent, provide a kind of applied widely, effect is obvious, and construction is simple, the compound soil-solidified-agent of organic-inorganic with low cost.
For achieving the above object, soil solidification of the present invention is made up of powder and liquid material, and the weight percent that it is characterized in that powder and liquid material is 9: 1.
(1) wherein powder composition and each composition weight per distribution ratio are:
Unslaked lime: cement: flyash: calcined phosphogypsum: compound additive=2: 1: 3: 0.33: 0.07
(2) liquid material composition and each composition weight per distribution ratio are
Modified acrylic acid emulsion: VAE emulsion: defoamer=3: 2: 0.03;
Above-mentioned cement is 425 ordinary Portland cements; Compound additive is made up of several tensio-active agents, multi-functional water reducer, retardant and exciting agent, mainly be made up of several industrial chemicals such as sodium stearate, sodium hydroxide, sodium sulfate, sodium phosphates, each component ratio is a sodium stearate: sodium hydroxide: sodium sulfate: tertiary sodium phosphate=1: 1: 2: 2.
The Suppress that modified acrylic acid emulsion selects for use U.S. ROM-HASS to produce.Suppress is a kind of vinyl/ACRYLIC EMULSION, and its key technical indexes sees Table 1.
Table 1Suppress technical indicator
The VAE emulsion be vinyl acetate between to for plastic and ethene through letex polymerization and copolymer water dispersoid, the VAE emulsion of selecting for use Beijing Organic Chemical Plant to produce.Its key technical indexes sees Table 2.
The technical indicator of table 2VAE emulsion
| Project | Index |
| Outward appearance | White is milk sap evenly |
| PH value | 4.0-5.0 |
| Non-volatile matter, % 〉= | 54.5 |
| Viscosity, mPa.s (25 ℃) | 500-1000 |
| Median size, u m | 2 |
In engineering was used, when making the subbase solidified earth, the volume of solidifying agent was approximately 4% of soil weight, and when making basic unit's solidified earth, the volume of solidifying agent is approximately 7% of soil weight.Adopt junction centre to concentrate the plant mixing method construction, be about to compound and concentrate batching, again compound is delivered to the making scene and constructed at junction centre
The advantage of the compound soil-solidified-agent of organic-inorganic:
(1) utilizes natural soil to be cured, gather materials on the spot, reduce the sandstone freight volume, save construction costs;
(2) soil solidification intensity can be adjusted arbitrarily, can satisfy the needs of different engineerings;
(3) anti-seepage effect is good;
(4) but the cured layer bearing certain pressure has certain weather resistance, argillization does not take place through water logging bubble;
(5) easy construction is quick, non-environmental-pollution;
(6) material price is cheap, but the reduction of erection time raises the efficiency.
Embodiment
Enforcement of the present invention is as described in the technical scheme, and those skilled in the art's modification to specifications can be implemented fully.
Claims (1)
1. a composite soil solidifying agent is characterized in that, it is that 9: 1 powder and liquid material formed by weight percent, wherein:
Each composition weight per distribution ratio of powder is: unslaked lime: cement: flyash: calcined phosphogypsum: compound additive=2: 1: 3: 0.33: 0.07
