Further, described cement is silicate cement; Described slag is the active material through the pyroprocess calcining.
Further, also include 0.2～2.0 weight part in the pulvis raw material of described sludge curing agent, main component is the naphthalene series high-efficiency water-reducing agent of polymethine sodium naphthalene sulfonate.
Further, described vitriol is saltcake.
Further, described sulfonated α-olefin can replace with the alkene sulfonate of 0.1～1.0 weight part, the hydroxyalkylated sulfonic acid salt of 0.1～1.0 weight part and the stilbene-4,4'-bis-(1-azo-3, 4-dihydroxy-benzene)-2,2'-disulfonate of 0.1～0.5 weight part.
Further, described sludge curing agent joins according to mass ratio 5～9% in the mud of unit mass, and wherein the optimum quality ratio is 7%.
Further, this sludge curing agent is as the application of the solidification treatment agent of building roadbase soil.
Further, this sludge curing agent also can be used as the application that sludge solidification that lake, river and seashore dredging desilting produces prepares earth working material.
Further, this sludge curing agent is as the application of the bottom antiseep treatment agent of river, lake, canal, reservoir water body.
Further, described a kind of sludge curing agent is as the application of the solidification treatment agent of building roadbase soil.
Further, the sludge solidification that produces as lake, river and seashore dredging desilting of the described a kind of sludge curing agent application for preparing earth working material.
Further, described a kind of sludge curing agent is as the application of the bottom antiseep treatment agent of river, lake, canal, reservoir water body.
Pulvis in this sludge curing agent is that each component is formed through levigate mixed preparing, it mainly passes through hydration reaction thing Dicalcium Phosphate (Feed Grade) and the tricalcium silicate absorption portion moisture of silicate, form crystallization particle and space net rack by active inorganic materials slag, be conducive to discharge moisture in mud as passage early stage, later stage is conducive to increase concretion body strength as skeleton.The liquor Main Function is to strengthen dehydration rate and dewatering speed.Pulvis can be added suitable quantity of water during use and be modulated into mud, then in proportion pulvis and liquor be joined in the mud.As join in the mud of water ratio 60～300%, can be pumped into longer-distance place, dewatering speed is fast, and the deposition concretion body strength is high.Join the rear fixed reinforcement of directly to stir, pave in the mud of water ratio 20～60%.After testing, the unconfined compression strength of mud after then indoor placement soaked 5 on the 2nd of mixing this sludge curing agent can reach 0.25～0.6Mpa, and has the characteristics of superior water-repellancy, water stability and the hydraulicity.Especially the pollutents such as contained heavy metal, pathogenic agent have been greatly reduced its rate of release by after fixed, the sealing in the mud, and good environmental-protecting performance is arranged.
Various slags have passed through high-temperature calcination such as cinder, aluminium ore slag, Iron-ore Slag, volcanic ash etc. in burning or industrial production, have very high physical activity, can effectively strengthen the fixed performance of solidifying agent.Add now the naphthalene series cement high efficiency water reducing agent of Commercialization application in the pulvis in this sludge curing agent, the consolidation effect of this sludge curing agent can strengthen accordingly.
When the mud roadbed that adopts this sludge curing agent to carry out road performance is processed, can suitably increase the ratio of mixing sludge curing agent, the performance of mud also can correspondingly improve simultaneously, when the mud water ratio approaches when building the subgrade soils optimum moisture content, directly the pulvis of admixture about 8% and about 0.1% liquor can make basic native intensity reach 2.1Mpa.And the domestic muddy foundation load bearing requirements of China is 0.08～0.25Mpa.
Sludge curing agent provided by the invention can be applied in the processing of road foundation, adopt this sludge curing agent that the basic soil of excavation is carried out consolidation process and compacting, its cost of building the road not only can reduce by 50%, and the properties of its roadbed is significantly better than conventional lime, sandstone roadbed, utilize this sludge curing agent to build the road, its evenness of road surface is bright and clean, the good intensity of plate body is high, weather resistance and good stability, high in the Different climate conditional stability, as freeze not split and burst and become muddy when a thaw sets in, meet water not soft not muddy.On equal highway layout strength level, but supercrust and groundwork thickness attenuate approximately 1/3rd.Can directly use as low-cost pavement in low traffic flow or its induration layer of remote districts.Use this sludge curing agent also can change the mud of dredging desilting into earth working material, after this sludge curing agent and mud stirred, can spread out and put on compacting, vacuum preloading, conveying belt extruding or centrifugal dewatering technology according to the difference of water ratio makes mud fixed in a short time, its induration can reach higher foundation bearing intensity, can be used for making the island, the base of building the road, ground is made in the cofferdam, and make material of construction etc., can not occur leaching through the immersion of long-term seawater fresh water and pollute and can keep certain intensity.
Adopt sludge curing agent provided by the invention that the soil body of the great water bodies such as river, lake bottom and side is carried out consolidation process, the substituted for plastic film is eliminated the plastic film construction to the disadvantageous effect of the eubiosiss such as water body periphery herbosa fully.And the permeability coefficient of its soil body can be adjusted by the incorporation of regulating sludge curing agent.Form of construction work can be according to the engineering specifications of locality, and the mode that the employing wet method stirs pave construction or dry mixing compacting construction realizes.
When using this sludge curing agent to carry out the curing of road base layer soil, the add-on of pulvis is for processing about 4% of native weight, and the liquor addition content can reach 3.8Mpa for processing about 0.04%, 7 days of native weight without the lateral confinement compressive strength after immersion.
Each component that this sludge curing agent adopts is the commercial goods or holds facile Industrial emissions, and cost of manufacture is lower, and the addition content when carrying out simultaneously the silt consolidation processing is few, and concretion body strength is high, water resistance good.Can be widely used in the solidification treatment of desilting mud, the reinforcement of road base layer soil and the antiseep of water bottom mud layer processes.
