Research on the Application of Renewable Concrete Based on Waste Mud in Urban Building Foundations
The disposal of mud waste caused by construction and tunnel digging is a major prob-lem in environmental management.The waste mud can be used as the backfill material in the field of building foundation reinforcement after the treatment of specific technology,and the waste resources can be recycled.Therefore,the renewable concrete is made on the basis of waste mud,and the influence of different reagent addition on the renewable concrete is studied.The results show that the water absorp-tion,fluidity and water resistance of the mud are improved,and the dry shrinkage rate is reduced by 6.6%.This indicates that the waste mud treated by the research method has feasibility and practical value as the foundation reinforcement material,and can promote the sustainable utilization of resources and environmental protection and development.
