Abstract
This invention relates to sand solidifying agent and its process method in field of non metal compound materials, which comprises the following steps: mixing the gesso powder, aluminium sulphate acetate cement, silicon powder, lithium powder and smectite power to form the final product through filtering and analysis and computing for fifteen minutes. The desert road by use of the solidify agent has the pressure proof ability in seven days as7.65Mpa higher than the same products in the filed by fifty percent.
Description
1, technical field: sand soil solidifying agent of the present invention and production method belong to the nonmetallic composite field.
2, background technology: the Xinjiang Takla Makan Desert is second-biggest-in-the-world mobile desert, and the underground hydrocarbon resources that is richly stored with is that the strategy of China's oil exploitation is taken over district and the " place, source of the gas ground of West-east Gas.For this region of exploratory development, at first to solve the problem of building highway on desert.Adopt conventional road building technology, not only road-making material famine, and traffic capacity is huge, and investment cost is high, and construction speed is slow, far can not satisfy the needs that oil-gas field development is built.Other sand soil solidifying agent of building the road at present and using, mix and make a gesture of measuring greatly, early strength is low, the weather resistance of desert highway is relatively poor, a lot of breakoff phenomenons such as expansion, cracking, protuberance, sedimentation and loss of strength that solidified engineerings appearance early, cause the curing engineering life-span to shorten the also corresponding increase of maintenance cost of highway greatly.There is the technical barrier of building highway on desert too in desert area on China Inner Mongol, Hebei, Shaanxi, Ningxia, Gansu and other places.
3, summary of the invention: the object of the present invention is to provide a kind of conventional road building technology of alternative tradition outward transport natural sand gravel material, good to reach the curing project durability, sand soil solidifying agent that comprehensive cost is low and production method.
The objective of the invention is to be achieved by the following technical programs:
1. utilize the specific surface area that improves various inorganic raw material micro mists, improve its activity, fast reaction speed, improve its gellifying property, play filling pore, the effect of cohesive force between the enhanced granule strengthens durable purpose to reach;
2. the cement equivalent coefficient of 28 days intensity of silicon powder is 2～5 times.Therefore, mix a spot of silicon powder replacement sulfur aluminate cement, with reach mix make a gesture of measuring less, effect that traffic capacity is few, high-strength, impervious;
3. selecting aluminosulfate cement and gypsum is gelling material, controls Al well
2O
3With SO
3Between ratio reach optimum value, generate low solubility, the needle-like crystal ettringite of high-bond is to solidify engineering early strong, high-strength, not shrinkage cracking and the good key of erosion resistance;
4. utilize useless lithium slag to be processed into micro mist as solidify material.Lithium slag micropowder contains the yttrium lithium, and elemental lithium can suppress the alkali silica reaction.When being used for cement concrete as adulterant, its tangible characteristics are low hydration heats, secondary hydration reaction, and good water-retaining property, workability are good.The certain proportion of controlling well can make the temperature shrinking percentage of solidifying engineering little, and later strength improves constantly;
5. utilize smectite micropowder as additive,, form the key of semi-rigid type base to reach good water-retaining property, cohesive strength height, little bloated feeding;
6. Gypsum Fibrosum micropowder, aluminosulfate cement, silicon powder, lithium slag micropowder and five kinds of raw materials of smectite micropowder are stirred through picking of raw material, composition analysis, computer metering, mixing by weight percentage and promptly made finished product in 15 minutes.
Proportioning 1: raw material and weight percent:
Gypsum Fibrosum micropowder 7.1～28.6%, aluminosulfate cement 7.1～57.1%, silicon powder 4.3～28.6%,
Lithium slag micropowder 2.9～28.6%, smectite micropowder 1.4～14.3%;
Production method: Gypsum Fibrosum micropowder, aluminosulfate cement, silicon powder, lithium slag micropowder and five kinds of raw materials of smectite micropowder were promptly made finished product in 15 minutes through picking of raw material, composition analysis, computer metering, mixing stirring.
Proportioning 2: raw material and weight percent:
Gypsum Fibrosum micropowder 7.1～25.7%, aluminosulfate cement 14.3～57.1%, silicon powder 7.1～25.7%,
Lithium slag micropowder 14.3～28.6%, smectite micropowder 7.1～21.4%;
Production method: the same.
In the above-mentioned raw materials, Gypsum Fibrosum micropowder specific surface area 〉=500m
2/ kg, SO in the composition
3＞42%, CaO＞30%.Aluminosulfate cement is 525
#Label.Silicon powder forms for the quartz sand grinding, its＜particle of 1 μ mm should＞90%, SiO in the composition

Because carry out such scheme, this sand soil solidifying agent can reach following effect:
1. 7 days unconfined compression strengths are 7.65MPa, are higher than like product about 50%, make the weather resistance of solidifying engineering improve a class.
2. contract with dry rate only is 0.01%, and less than about 50% of like product, desert highway is shrinkage cracking not, and erosion resistance is good, fast on year-on-year basis 3 days of open to traffic.
3. when its groundwork thickness of desert highway was 200mm, 9 days the modulus of resilience reached 524MPa, and the flexure typical value is 65.
4. the long 1000m of every build, wide 10m, the desert highway of thick 0.15m, compare with the traditional road building technology that adopts the natural sand gravel material, the construction material traffic capacity only be its 6.33%, the solidifying agent usage quantity is only planted about 50% of solidifying agent for him, and the cost of building the road reduces greatly, reduces investment outlay about 100,000 yuan for every kilometer.
