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.
