The Development Of New Non-clinker Incorporating Soda Residue Curing Agent And Experimental Study On Its Soil’s Mechanical Properties

Adhere to the road of sustainable development is a long-term basic national policy.The sustainable development’s core is recycling utilization of resources, industrialwastes, as a special resources, how to change it into resources, and along withrecycling road, is a research task with realistic meaning.The soda residue and the flue gas desulfurization (FGD) gypsum are commontypes of industrial reject. The soda residue is the industrial waste in the pure sodaprocess which was produced by the ammonia-soda method, the FGD gypsum is a kindof by-produced in the power stations. Over the years, these two kinds of solid wastewith a low level of comprehensive utilization, and the most commonly usedprocessing method is in-situ accumulation. However, the processing method that usedin in-situ accumulation not only the occupation of cultivated land, and destruction ofecological environment.Firstly soda residue, slag and fly ash were taken as main raw material, appropriateamount desulfurized gypsum was mixed and a little activator was compound addition,the ball mill process for further processing, fully arousing their activity to prepare soilstabilizer—new non-clinker incorporating soda residue curing agent with reaching thetechnical requirements of32.5composite cement on physical and mechanicalperformance. Based on orthogonal test, we explored the dosage of all kinds ofminerals impact on the performance of clinker-free cementing material, such asstrength, stability,standard consistency water quantity and setting time. We got thebest of the the mix design about the mineral composition. In order to further study thebest proportion of the new type non clinker sludge curing agent performance, so thearticle maintenance and durability, hydration heat and microscopic were analyzed.Finally we found that the hydration products of this curing agent is similar to thecement. In order to study the engineering characteristics of the new non-clinkerincorporating soda residue-stabilized-soil, through setting up five kinds of mixingratio of the new non-clinker incorporating soda residue curing agent from the soilconsolidation14d,28d and90d three ages of unconfined compressive strength test,splitting tensile test, compression test, triaxial compression test, and the newnon-clinker incorporating soda residue-stabilized-soil’s compressive strength, tensilestrength, shear strength and stress-strain relationship of test results were analyzed toprovide theory support on the new curing agent materials in practical engineering theapplication.The author contrasted14d,28d and90d’s test results between the the newnon-clinker incorporating soda residue-stabilized-soil and the same label compositecement-soil, thus further studying the curing agent as the feasibility of soilstabilizer.From the mechanisms of strengthening of a series of chemical reactions wasproduced by the new non-clinker incorporating soda residue curing agent in water andwas complex chemical reacted in the soil, and combining the strong basic role fromthe problems, probing into the influence mechanism of the new non-clinkerincorporating soda residue-stabilized-soil’s mechanics performance.
