Problems solved by technology

In recent years, my country has introduced a large number of imported ionic soil stabilizers, and their use has achieved certain success. However, due to their high requirements on soil quality and high prices, there are not many practical applications.
At present, domestic curing agents are only suitable for some soils, and cannot adapt to various types of soils. The domestic independent research and development and production of compound ionic soil curing agents are still in their infancy.

Embodiment example 1

[0028] In laboratory state:

[0029] According to the "Soil Engineering Test Regulations", take the soil sample through a 5mm sieve, add 4% of 32.5 grade cement to the outside, and configure a composite ion soil curing agent according to the proportion of 0.02% of the volume of the test block, and mix it with an appropriate amount of water to dilute and mix it. into a 50mm × 50mm test piece. There are 45 in 5 groups, according to the "Technical Regulations CJJ / T80-98 for Cured Pavement Base and Subbase", "Soil Stabilizer 3073-1998" and "JTG E51-2009 Highway Engineering Inorganic Binder Stable Materials Test Procedures" and operate and For the test, 3 specimens were taken from each group, and the unconfined compressive strength reached 3.60Mpa on average for 7 days (6 days of standard cultivation + 1 day of water immersion), which met the design requirements of expressway roads; (27 days of standard culture + 1 day of water immersion) the unconfined compressive strength reache...

Embodiment example 2

[0033]The factory road in an industrial zone in the central part of Guangxi was selected. The paved area is about 20,000 square meters. The construction time is from January to May 2010. The soil liquid limit in this area is 44%, the plastic limit is 24%, and the plasticity index is 20. It belongs to clayey soil. The mixture ratio of road base course is, soil curing agent: calcium carbide slag: plain soil = 0.02%: 3%: 97%; : 3%: 3%: 94%, wherein, the cement is 32.5 grade ordinary cement, the carbide slag is the industrial waste of PVC enterprises, and the main component is Ca(OH) containing saturated water 2 , plain soil is the soil that needs to be shipped out during the construction of the plant. After the construction is completed, the subgrade will be inspected by the inspection unit. The compaction degree of the pavement base and subbase has reached more than 95%, the deflection value is only in the range of 60-100 (0.01mm), and the rebound modulus is between 125.5-217MP...

Embodiment example 3

[0035] Select the municipal road in the new development zone of a city in Guangxi District, with an area of ​​about 1,800 square meters. The soil in this area belongs to weak expansive soil, and the local government has clearly stipulated that the soil cannot be used as roadbed backfill soil without treatment. The mixture ratio of road base course is, soil curing agent: carbide slag: plain soil=0.02%: 6%: 94%; the mixture ratio of road base course is soil curing agent: cement: calcium carbide slag: plain soil=0.02% : 3% : 6% : 91%. After the project is completed, the testing unit will test the compactness and rebound deflection value. After testing, the compaction degree of the base layer is above 97%, representing a deflection value of 159.8 (0.01mm); the compaction degree of the base layer is above 98%, representing a deflection value of 47.8 (0.01mm), all reaching or even exceeding the design Require. The soil used in this project is the accumulated waste soil developed ...

Abstract

The invention relates a composite ionic soil curing agent and a manufacturing method thereof, aims at providing a high-efficient geotechnological building new material for highways, municipal administration, slope protection, water conservancy dams, building foundations and building anti-seepage works and belongs to the technical field of fine chemistry industry. The manufacturing method comprises the following steps of: enabling four components, namely a strong oxidant, an activating agent, a dispersing agent and a curing catalyst, to react and age in a reaction kettle according to the proportion that the percent by weight of ingredients (1) and (2) of the activating agent is 3% respectively, controlling the temperature at 30-32 DEG C, then adding the dispersing agent, uniformly stirring, reacting for 60 minutes, finally adding concentrated H2SO4, and controlling the reaction temperature below 60 DEG C so as to form the composite ionic soil curing agent. When the composite ionic soil curing agent is applied to construction, the using quantity accounts for 0.01-0.1% of the volume of a cured structure after compaction, after the composite ionic soil curing agent is diluted with water, the composite ionic soil curing agent is uniformly sprayed into soil mixed with other inorganic binders, uniformly mixed, rolled, compacted and maintained for a certain period of time, and then the effect of curing the soil in a stable and lasting manner is further achieved.

Description

technical field [0001] A compound ionic soil solidifying agent and its manufacturing method provide high-efficiency geotechnical construction new materials for road, municipal, slope protection, water conservancy dams, building foundations and building anti-seepage projects, and belong to the technical field of fine chemicals. Background technique [0002] Soil hardener is a soil hardener that can directly cement the surface of soil particles in the soil or react with clay minerals to form gelatinous substances at room temperature. In the 1970s, soil stabilizer, as a new type of curing material, was widely used in developed countries such as Europe and the United States. Due to its superior performance, soil stabilizer has been widely used in the construction of water conservancy, transportation, environment, ports, airports and other infrastructures, and has achieved remarkable results. In recent years, four new types of soil stabilizer products, inorganic, organic, bioche...
