specific Embodiment 1

[0043] A marine dredging and mud flat solidification material whose components (mass percentage) are: 40% slag powder, 20% fly ash, 24% cement, 10.3% calcium oxide, 4.7% citric acid waste gypsum, 0.3% lignin, Activator 0.7%. The fineness of slag powder is 400m 2 / kg; the fly ash is grade C, the CaO content is not less than 10%; the digestion temperature of calcium oxide is not lower than 60°C, and the digestion time is medium speed; the cement grade is not lower than #325 and early-strength cement is not allowed.

[0044] The active deodorant is sprayed at 0.1% of the mass of the sludge during the input and stirring process of the sludge.

[0045] Configure marine dredging and beach mud solidification materials according to this ratio, and mix 80kg of solidification materials (stir evenly) into each cubic meter of mud (silt moisture content is controlled below 80%), and the active deodorant is when the mud is input and stirred. Apply surface spray. After the sludge is solid...

Abstract

The invention discloses a solidifying material for marine dredging and tidal flat sludge. The solidifying material comprises slag micropowder, fly ash, cement, calcium oxide, citric acid waste gypsum, lignin, an activator and an active deodorizing agent. The technical problem solved by the present invention is that: the sludge solidifying material is added to the marine dredging and tidal flat sludge during stirring, such that the problem of solidification and engineering utilization of the marine dredging and tidal flat sludge is solved. With the solidifying material for the marine dredging and tidal flat sludge provided by the present invention, the waste gypsum, the slags, the sawdust and other industrial and mining waste materials are completely utilized as the fillers and the addition agents for solidifying the marine sludge, such that the mechanical property, the building practicality and the environmental protection performance of the solidified product of the marine sludge areensured, and the complete and rational utilization of the natural sludge and the industrial waste material is realized.

Description

[0001] technical field [0002] The invention relates to a solidification treatment material for silt and muddy soil with high water content, in particular to a solidification material for ocean dredging and tidal flat silt. [0003] Background technique [0004] In engineering construction and social infrastructure construction, a large amount of earthwork and relatively strong basic materials are required. Although stone is a high-strength infrastructure material suitable for large-scale applications, at present, both society and the country are demanding environmental protection. Under the premise, as a non-renewable natural resource, the mining of stone is subject to national monitoring and restrictions. In this case, it is very necessary to seek substitute products for stone materials. Similarly, the market prospect of this substitute product is very ideal under the premise of uninterrupted engineering and social infrastructure. [0005] my country has a long coastlin...
