磷石膏二灰稳定锰渣基层材料的研究

Study on the Basecourse of Phosphogypsum, Lime and Fly-ash Stabilizing Manganous Slag

对锰渣作路面基层材料进行试验研究。研究结果表明 :石灰粉煤灰稳定锰渣 7d强度可达 1.15 MPa,满足高速以及一级公路石灰粉煤灰稳定类基层强度要求 ;磷石膏对石灰粉煤灰稳定锰渣的早期强度具有显著的增强作用。

The basecourse from manganous slag is studied. Experiment results showed that the strength of lime, fly-ash stabilizing manganous slag is over 1.15 MPa after curing for seven days, so it can be used as the basecourse of highway; phosphgypsum improves the sever-day-strength of lime, fly-ash stabilizing manganous slag greatly.
