摘　　要：通过对LNC 5 3型负温混凝土防冻泵送剂性能的研究 ,总结了掺防冻泵送剂负温混凝土在负温条件下强度发展规律。结果表明 ,掺LNC 5 3型负温防冻泵送剂可在 - 5～ - 1 5℃的条件下确保结构实体混凝土强度能持续增长 。Based on the research on the properties of LNC-53 anti-freezing pumping admixture,strength development law of the concrete with that admixture under -5℃,-10℃,-15℃ was summarized.The results show that the strength of the concrete with this kind of admixture can develop continuously without being frozen.
