摘要
国内开展高掺量粉煤灰水泥混凝土路面的地方较多 ,线路较长的公路上 ,尚无修筑路面质量较好的。本文介绍近 3年来开展高掺量粉煤灰水泥混凝土路面课题研究的情况。通过近 1km实地试验说明粉煤灰替代 40 %水泥 ,加入减水剂、激发剂的混凝土具有后期强度很高 。
There were a lot of tests in cement concrete pavement construction with high percentage fly?ash but there is no one succeeded in long highway. This paper introduces the procedure and the result of the theme, cement concrete pavement with high percentage fly?ash, in last 3 years The test road is about 1 kilometer with 40% percentage of cement was replaced by of fly?ash This kind pavement with water reducer and stimulator has the characteristics of high late-strength, good work ability and high wearing resistance
