The results show that, by selecting the appropriate antifreezing agent and optimizing the mix proportion, NTC is capable of frost-resistance, and the strength of NTC can increase continually under negative temperature and the mechanical properties of NTC will not decrease after the temperature rises above zero. 结果表明,通过选择合适的防冻剂,优化混凝土配合比,能保证负温混凝土具有抵抗冻害的能力并在负温条件下强度持续增长,转正温后混凝土各项物理力学性能不降低。

With rapid development of concrete's additive techniques in our country, the antifreezing agent is increasingly widely adopted. 随着混凝土外加剂技术在我国的迅猛发展,防冻剂也越来越多的被采用。
The suitable percent of the sodium nitrite as antifreezing agent was obtained. 得到了亚硝酸盐钠作为防冻剂的最佳掺量。
In this paper through adoption of UEA expansion agent, TQ-ⅲ antifreezing pump agent and warming shed the mass concrete's temperature is controlled, so that the frost damage and cracks are prevented. 通过掺加UEA膨胀剂、TQⅢ大体积混凝土防冻泵送剂,并采用暖棚法对大体积混凝土进行了温度控制,防止了大体积混凝土的冻害和裂缝的产生。
Determination of the Amount of Blended Concrete Antifreezing Agent 怎样确定混凝土防冻剂掺量
With time passing the survival rate of tachyzoites was downing, but at the end of the six month both the tachyzoites had successfully infected mice which frozen with the former two antifreezing agent. 随着时间的推移速殖子的存活率下降,但在6个月末两种方法冻存的速殖子都能成功感染小鼠。
