本文介绍了CTF混凝土增效剂在C50预应力桥梁中的试验研究与应用,并分析了CTF混凝土增效剂对C50混凝土性能的增效作用。使新拌混凝土的流动性、粘聚性、保水性、保坍性等施工性能进一步提高,后期强度和抗渗性能有所提高。在降低原水泥用量12%的情况下能保持原有强度不变。
This paper introduces the experimental research and application of CTF concrete synergist in C50 prestressed bridge and analyzes the synergistic effect of CTF concrete synergist on C50 concrete performance. So that the flow of fresh concrete, cohesion, water retention, Paul slump and other construction performance to further improve the strength and impermeability improved later. In the case of reducing the amount of the original cement 12% to maintain the original strength unchanged.
