Abstract

The invention relates to a harbor construction land reclamation material composition prepared from silt. The composition is prepared by mixing the following raw materials in weight proportion: 1 to 5of silt, 1 to 5 of tailing sand, 1 to 5 of carbon residue, 0.04 to 0.06 of cement and 0.004 to 0.006 of non-ionic surface active agent, wherein a water content of the silt is 70 to 90%, and the non-ionic surface active agent is chosen from high-carbon fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether or fatty acid polyoxyethylene ester. By means of the composition disclosed bythe invention, waste use of the tailing sand and silt is achieved. The composition disclosed by the invention has the advantages of high strength and low construction cost; furthermore, quick solidification of the silt is achieved, and a lot of natural resources are saved. The composition disclosed by the invention can be applied to projects of hydraulic reclamation of sand, a filter guiding layer, a sand cushion layer, land area backfill and the like.

Description

technical field [0001] The invention relates to a new building material for port engineering, in particular to a port construction reclamation material composition using mud. Background technique [0002] Port engineering construction requires a large amount of sand and gravel resources. Along with environmental protection, sand and gravel resources are becoming increasingly tense, which seriously restricts the speed and quality of port construction. Port construction requires the dredging of a large amount of silt. In the past, the silt was dumped out to sea, causing waste and pollution. Due to the fine silt particles, high water content, and poor physical and mechanical indicators, the silt must be treated during port construction, and the silt must be excavated and land reclamation, which is used as a foundation after drainage and consolidation. Vacuum preloading and surcharge preloading technologies and processes are commonly used for sludge drainage consolidation, but ...
