Study Of Road Performance Of Saponification Slag Stabilization Soil

Saponification slag is a kind of waste residue which generated in the process forthrough chlor-alkali process the production of propylene oxide, Because it is thewaste residue of the saponification stage produced, so named for the saponificationslag. There are a number of production of propylene oxide chemical companiesnationwide, the annual output is nearly one million tons of waste saponificationslag,Scrap pile up like a mountain,these saponification slag occupied the factory landand difficult to deal with，And have the impact on the environment,.How to deal withthese industrial residue is urgently needed to solve.The main component of saponification slag is Ca（OH）₂, it can replace the lime assubgrade filling material, not only resolve the problem of accumulation of wasteresidue, waste, and achieved certain economic benefits, but also has good effect onthe environment.The current output of saponification slag chemical companies are mostlyconcentrated in the North seasonal frozen region, to obtain raw material locallyconcept, if you want to use saponification slag, the best is paved to the nearest road,the main reference of the performance test of saponification slag road were studied theroad environmental conditions near saponification slag areas.This paper from saponification slag contains composition can generate chemical characteristics of cement system, physical properties of high fineness, toanalyze the possibility of it as subgrade filling material，Then road performance tests of the saponification slag combined with soil were carried out：Determine different age saponification slag Stabilization Soil unconfined compressive strength,and tensile strength, through which to judge as paving material strength is meet the qualification.this paper tests prove that the saponification slag binder can meet the requirements of road base strength standard. And the seasonal frozen region characteristics and water stability was studied, including the frostresistance, dry shrinkage, temperature shrinkage, permeability, water stability research.
