Abstract
The invention relates to a quick sea coating mud consolidation agent which uses coal ash and slag as main materials, and meanwhile, a hydraulic setting gelled material, an alkaline exciting agent, an expanding agent, a surface active agent, a water reducing agent, a coagulating agent and an auxiliary agent by a certain proportion are also matched and mixed, i.e. the consolidation agent comprises the following components in percentage by weight: 52-60 percent of coal ash, 18-25 percent of slag, 5-15 percent of hydraulic setting gelled material, 5-10 percent of alkaline exciting agent, 5-8 percent of expanding agent, 1-2 percent of surface active agent, 1-2 percent of water reducing agent, 1-2 percent of coagulating agent and 1-2 percent of auxiliary agent. The quick sea coating mud consolidation agent has the advantages of high solidification speed, high strength, good stability, strong durability, no pollution, and the like, thus the sea coating mud is changed into a useful earthwork resource, which not only regenerates waste resources, but also creates social and economic benefits.
Description
Technical field
What the present invention relates to is a kind of rapidly solidified material that is used for tidal land mud, is applicable to the rapidly solidified processing of high-moisture percentage and soft viscosity mud.
Background technology
Along with China's Coastal Areas national economy is fast-developing, to enclose and cultivate area and enlarge day by day, the required sand of backfill, building stones reduce gradually, and in order to strengthen ecological the maintenance, the sandstone material can not be exploited in a lot of places.At these China's Coastal Areas great majority is sedimentary for many years soft viscosity mud, and the mud of hydraulic reclamation is difficult to fixed for the moment.To the rapidly solidified construction of soft viscosity tidal land mud; Present domestic sand bedding course draining and the vacuum preloading junction logos generally all also continued to use; Deep layer is taked the plastic draining board method; Also just solve the soil body self discharging consolidation through handling, be difficult to improve for the moment the soil body self intensity, not only cost height but also processing back bearing capacity still are difficult to satisfy the requirement of construction equipment construction ability.
Along with development of science and technology; Dredging silt solidifying agent such as rivers, lake has also obtained application more and more widely at home and abroad gradually, and this type of solidifying agent is mainly continued to use the simple mixing of cement, lime, flyash or these materials, and price is higher than the cement valency; Be not suitable for the higher tidal land mud of water ratio; And it is not high to solidify the back soil body self intensity, and water stability is poor, and secondary dissolves easily.Tidal land mud is because self mineral composition is complicated, high, the soft viscosity of water ratio is strong, and PQ is generally 10
-9Cm/s~10
-7Characteristics such as cm/s are difficult to dewatering and coagulating; And the back filled region later stage needs development & construction, and requirement of strength is high, and the duration is short, moreover the immersion that receives the tide nighttide with wash away, water stability requires high; Restricted by the marine eco-environment, backfill all can not pollute environment with curing.Restricted by above factor, traditional solidifying agent is difficult to satisfy the development & construction demand of hydraulic reclamation tidal land mud.
For solving the development and use of hydraulic reclamation tidal land mud; The immersion that need develop then that a kind of curing speed is fast, consolidation strength can satisfy backfill development & construction demand and stand coastal morning and evening tides with wash away; Environment is not caused rapidly solidified dose of the novel tidal land mud of any pollution, important social and economic significance is arranged advancing economy development of coastal area.
Summary of the invention
Technical problem to be solved by this invention provides a kind of mineral composition comparatively complicacy, high-moisture percentage, soft viscosity, rapidly solidified material of low intensive tidal land mud of being applicable to; Through in tidal land mud, adding rapidly solidified dose of tidal land mud, it is rapidly solidified that tidal land mud is obtained, and bearing capacity is improved, and fixed back water stability is good, and pollution-free, and attaching different ingredients according to the soil property building requirements becomes the engineering materials that alternative building is banketed.
The technical scheme that the present invention adopts is:
The present invention be with flyash, slag as main raw, be equipped with a certain proportion of hydraulic cementing materials, alkali-activator, swelling agent, tensio-active agent, water reducer, peptizer and auxiliary simultaneously and mix.Each component is following by mass percentage:
Composition quality is formed %
Flyash 52~60
Slag 18~25
Hydraulic cementing materials 5~15
Alkali-activator 5~10
Swelling agent 5~8
Tensio-active agent 1~2
Water reducer 1~2
Peptizer 1~2
Auxiliary 1~2
According to different shale characteristics with flyash, slag, hydraulic cementing materials, alkali-activator, swelling agent, tensio-active agent, water reducer, peptizer, auxiliary with specific mixed, mix through special whipping device then and get final product.Each composition quality composition is meant that each composition quality accounts for the per-cent of prescription medicament total mass.
Characteristic and main chemical compositions thereof through analyzing tidal land mud are formed; To self chemical property of tidal land mud, respectively from reduce tidal land mud water ratio, regulate tidal land mud active, improve tidal land mud solidification intensity, the soluble tissue that reduces pollutent developed rapidly solidified dose of this kind tidal land mud.Rapidly solidified dose of activity of giving full play to tidal land mud unit mineralogical composition mesosilicic acid salt mineral of tidal land mud; Produce curing reaction fast, not only produce mortise, and can generate expanded gum material with the active substance reaction in the tidal land mud particle at the sludge granules phase interface; Produce combination through chemokinesis; Both produce physical bond, can also seal heavy metal, organism up for safekeeping simultaneously, prevented the stripping of objectionable impurities; Make the soil body self produce the high-intensity while, also have good water stability and weather resistance.
After tidal land mud adds the MFF agent, 7 days and 28 days detected results.
The beneficial effect that the present invention has is: advantage such as rapidly solidified dose of tidal land mud has that curing speed is fast, intensity is high, good stability, weather resistance are strong, pollution-free; Thereby become useful earthwork resource to tidal land mud; The waste resource of both having regenerated has been created economic results in society again.
