低活性粉煤灰基层材料路用性能试验研究

Experimental research of the road performance of low activity fly-ash base course

对热电厂排放的粉煤灰进行了系统的室内试验研究,分析了该试验用粉煤灰材料的化学组成,研究了粉煤灰基层材料的强度、干缩和温缩性能、抗冻及抗冲刷性能等,指出科学地选用添加剂激发低活性粉煤灰的活性,合理地使用该种材料,将之应用于公路建设是可行的。

It makes a systematical indoor experimental research of the fly-ash discharged by power plant, analyses the chemical constitution of this fly-ash for experiment, makes a research of the strength, dry shrinkage and temperatureshrinkage property, antifreeze and anti-washout property of fly-ash base course, and points out that choosing additive scientifically to activate the activity of low activity fly-ash, using this material reasonably and applying it in highway construction is feasible.
