摘要
Abstract
In this study,the sediment of Shanghai Chongming District river was used as the main raw material.By using non-sintering technology,orthogonal experiment was used to analyze the different proportions of the base curing agent and determine the preferred formula of the curing agent and the amount of the admixture.This formula was used to study the ratio of water to solids,the amount of ash and curing agent added to obtain the optimum ratio of the prepared porous material of ecological revetment.The performance of the material and the experimental study of phosphorus adsorption were also studied.The basic formula of curing agent was 40％cement,30％quicklime,10％gypsum and 20％alumina.The amount of foaming agent was 0.2％of the total curing agent,and the amount of the polycarboxylic acid water-reducing agent was 1％of the total curing agent.The better technological parameters for the preparation of sludge porous materials were water-cement ratio of 0.25,the ratio of curing agent to sediment of 0.32,and the ratio of ash to sediment of 0.15.The research results can provide technical support for in-situ utilization of riverbed sediment to construct ecological slope protection.关键词
