Abstract
The invention relates to a compound type slurry curing agent for conducting curing treatment on waste slurry generated in geotechnical engineering (for example, investigation drilling, cast-in-place pile, anchorage engineering, trenchless construction and the like), as well as the sludge at the bottom of reservoirs, ditches, ponds, pools and the like. In the invention, the compound type slurry curing agent is prepared by adding and mixing fine sand, lime, industrial waste gypsum and super absorbent resin in cement curing agent evenly according to a certain proportion. The slurry curing agent greatly improves the curing effect of slurry, reduces the use amount of cement and lowers the cost. Besides, by doping industrial wastes such as waste gypsum in cement, the pollution to the environment is abated, the recycle of wastes is promoted and favorable economic and social benefits are available.
Description
Technical field
The present invention relates to a kind of slurry curing formula, be applicable to the waste mud that produces in the geotechnical engineering (as prospecting boring, castinplace pile and anchoring engineering, non-excavating construction etc.), and the solidification treatment of bottom sludge such as reservoir, water channel, the pool, pond, belong to civil construction material technology field.
Background technology
The a large amount of waste muds that produce in the geotechnical engineering construction (as prospecting boring, castinplace pile and anchoring engineering, non-excavating construction etc.), the mainly suspension of forming by clay, sewage, sump oil, drilling cuttings and mud conditioner and the mixed body of colloidal solution, can pollute to environment, bring negative impact to construction.Be embodied in: the waste mud that engineering construction produces is difficult to degraded under state of nature, cause the surrounding area soil compaction, soil salinization, vegetation considerable damage; The waste mud long-term accumulated is penetrated under the face of land water layer or with the excessive inflow rivers of rainwater brook, polluted source directly or indirectly produces harm to animal, plant and human health, as is used as assorted soil outward transport, can cause secondary pollution; In addition, dirty mud sump is idle for a long time, takies valuable land resources.The purpose that waste mud is cured processing is that waste mud is not polluted surrounding environment, slurry (or cream) the shape storage configuration that changes waste mud simultaneously is the solid attitude, make its solid that changes into similar soil or glued become the bigger solid of intensity, on the spot landfill second ploughing or as material of construction.
To the solidification treatment of mud, generally adopt cement, lime etc. at present as solidifying agent.Because Portland cement, lime setting and harden are slow, they had the part sedimentation before will occurring not condensing under the high water-solid ratio situation, and contain more organic substance in the mud usually, these organic substances can hinder the hydration reaction of cement, cause cement that the effective adhesive cohesive soil can not be arranged, so the solidification effect of grout is often very poor even can't carry out.When using lime to solidify, solidification intensity is lower.In addition, adopt Portland cement as the required cement mixed ratio of slurry curing agent about 10%, involve great expense and caused the huge wasting of resources.
The present invention has developed a kind of compound slurry curing agent by add materials such as fine sand, industrial waste gypsum, lime, super absorbent resin in Portland cement.This solidifying agent has improved the solidification effect of mud greatly, has reduced cement consumption, has reduced cost.In addition, in cement, mix industrial wastes such as waste gypsum, reduced environmental pollution, promoted the recycle of waste material, had good economic benefit and social benefit.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can be applied to the high-performance of actual slurry curing engineering, cheap slurry curing agent.Industrial wastes such as waste gypsum have been mixed in this slurry curing agent in cement, reduced environmental pollution, have promoted the recycle of waste material,
Slurry curing agent of the present invention, wherein the cement quality ratio is 27%～31%, and fine sand mass ratio 35%～39%, lime quality are than 3%～5%, and gypsum quality is than 27%～31%, and the super absorbent resin mass ratio is 0.8%～1.2%.
Slurry curing agent of the present invention, the cement that is adopted is the ordinary Portland cement of label 425.
Slurry curing agent of the present invention, the fine sand that is adopted is the sand of fineness modulus 1.7.
Slurry curing agent of the present invention, the lime that is adopted is dry hydrate, Ca (OH)
2Content is 85%, fineness 300 orders.
Slurry curing agent of the present invention, the gypsum that is adopted are power station desulfurization waste gypsum, wherein: sulphur trioxide＞42%, water ratio＜10%, particle diameter＜200mm.
Slurry curing agent of the present invention, the super absorbent resin that is adopted is " converging gloomy " board HS series super absorbent resin.
Beneficial effect of the present invention: this high-performance mud prescription, only need in advance in proportion with cement, fine sand, lime, gypsum, super absorbent resin stir and get final product.Regulate curing agent ratio according to water content of slurry then, the intensity of solidifying back slurry curing body can mixing than realization by the adjusting solidifying agent.This solidifying agent has improved the solidification effect of mud greatly, has reduced cement consumption, has reduced cost.In addition, in cement, mix industrial wastes such as waste gypsum, reduced environmental pollution, promoted the recycle of waste material, had good economic benefit and social benefit.
Embodiment
Embodiment 1
Adopt mortar testing routine size, specimen size is 70.7mm * 70.7mm * 70.7mm.Treat that solidified mud is certain building site cast-in place pile expense mud, water ratio 200%, density 1.36g/cm
3Inject die trial after solidifying agent and the mud uniform mixing, manual inserting smash, and makes the mud face be higher than die trial 3～5mm, and an end of mentioning die trial vibrates 5～10 times, and the other end of mentioning die trial again vibrates 5～10 times, scrapes plane surface.In 20 ℃ of following maintenance 24h demoulding, put into the standard curing room maintenance behind the test block forming.Surveyed the unconfined compression strength of slurry curing body to the 7 day length of time.The solidifying agent preparation raw material is: the cement that is adopted is the ordinary Portland cement of label 425; The fine sand that is adopted is the sand of fineness modulus 1.7; The lime that is adopted is dry hydrate, and Ca (OH) 2 content are 85%, fineness 300 orders; The gypsum that is adopted is a power station desulfurization waste gypsum, wherein: sulphur trioxide＞42%, water ratio＜10%, particle diameter＜200mm; The super absorbent resin that is adopted is " converging gloomy " board HS series super absorbent resin.
The component prescription that process is joined in the solidifying agent examination sees Table 1～4, and the mud that every assembly side reinforced is 500ml.Various material permissible variations see Table 5 in the process for preparation.
Each composition weight proportioning of process is joined in table 1 slurry curing agent examination

By above each example as seen, only with cement during as solidifying agent, when its volume was 40g, mud was difficult to moulding, can not satisfy movement requirement.For compound solidifying agent, along with the increase of cement mixed ratio, intensity increases, and the final setting time of mud shortens; Along with the adding of super absorbent resin, intensity increases, but when super absorbent resin volume during greater than 0.5g, the intensity raising is not obvious; Along with the adding of super absorbent resin, the final setting time of mud significantly shortens, but when super absorbent resin volume during greater than 1.0g, not obvious to the influence of mud final setting time.
By above test-results as seen, adopt fine sand: 25g, lime: 2.5g, cement: 20g, gypsum: 20g, the intensity (the 7 day length of time) of the hardener formula of composite curing agent prescription and the cement of super absorbent resin: 0.5g: 55g (satisfying the minimum cement mixing content of mud movement requirement) maintains an equal level, and it is about 60% that the mud final setting time shortens, and satisfies the engineering requirements on transport simultaneously and can save construction costs 20%.
