负温下HPC粉煤灰最佳取代率试验

Test of the Best Replacement Rate of HPC Fly Ash under Negative Temperature

本研究致力于节能利废绿色思想,通过试验得到负温下HPC满足抗冻、干缩、水胶比等性能条件下的最佳粉煤灰取代率,用以指导及完善寒冷地区施工中需要注意的一些主要问题.

Focusing on energy-saving and waste-using idea , through experiment ,the best replacement rate of HPC under the condition of negative temperature and meeting the performance of anti-freezing,shrinking and the appropriate water-cement ratio,is obtained to guide and improve the construction quality in cold areas.
