Study Of The Stabilized Soil Of Acetylene Sludge As Base Course In Highway Project

Acetylene sludge, which main composition is Ca(OH)2, is a by-product of chemical factories when they produce PVC by calciun-carbide-method. The whole output of PVC is 884 thousand tons in china in 1998,with 16-17 million tons of acetylene sludge, the PVC's yield is increasing every year in addition. So much acetylene sludge needs a large cover of field to deposit with a terrible smell, at the same time they pollute the surround environment.How to make full use of acetylene sludge to reduce the pollution?How to make the acetylene sludge profit us?According to acetylene sludge is one kind of substandard lime, in this study, I use acetylene sludge to stabilize granule soil instead of lime. The intensity, rigidity, water stability, shrinkage index of acetylene sludge stabilization is the same as the index of lime stabilization.Acetylene sludge stabilization granule soil can be used as bottom course of all highway. Acetylene sludge-fly ash stabilization granule soil can be used as bottom course of all highway.These courses are all used in several highways project with good performance.The price of s acetylene sludge is not high, which mainly rest with the transportation expenses.It can save cost in highway project, if we use s acetylene sludge within the economic radius. It can make economic benefit, society benefit as well.
