Quick sea coating mud consolidation agent

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 [0001] The invention relates to a rapid consolidation material for sea mud, which is suitable for rapid consolidation treatment of high water content and soft viscous mud. Background technique [0002] With the rapid development of the national economy in my country's coastal areas, the reclamation area is expanding day by day, and the sand and stone materials required for backfilling are gradually decreasing. In order to strengthen ecological maintenance, sand and stone materials cannot be mined in many places. Most of the coastal areas in my country are soft and viscous silt deposited for many years, and the dredged silt is difficult to consolidate for a while. For the rapid consolidation construction of soft viscous tidal mud, at present, the combination of sand cushion drainage and vacuum preloading is generally used in China, and the plastic drainage board method is adopted for the deep layer. After treatment, it only solves the drainage and consolidatio...
