摘要
阐述了YNB-5型防冻泵送剂的研究技术路线,受检砼拌合物和硬化砼性能、工程试验及影响可泵性的因素及解决方法。
A technical approach of the YNB-5 antifreezing-pumping agent and the properties of the concrete mixtures and hardened concrete with agent ae well as the factors which influence the pumpability were introduced in the paper. The studies indicated the varied properties of the concrete mixtures after pumping and the method to solve the problem of frost resisting concete with high slump.
