摘要
针对碾压混凝土稠度控制问题,通过对拌和时间、含水率、放置时间对碾压混凝土稠度的影响进行试验研究,并与碾压混凝土摊铺、碾压现场适宜的稠度范围相结合,得出了碾压混凝土施工中的稠度控制技术,为具体工程提高作业效率和施工质量提供理论基础。
Consistency changing rule,which is affected by the mixing time,water content,transportation and waiting time,was found based on indoor test of roller compacted concrete.The consistency control technology for construction was given,combined with appropriate scope of consistency at the scene of roller compacted concrete paving and the characteristics of water supply system and the changes of water content in aggregate.
