中文摘要：

阐明了预湿轻骨料的工作机理，归纳概述了轻骨料预湿后对混凝土各项性能指标的影响。从济南遥墙机场的实际应用及混凝土工作性、强度、抗冻性等指标出发，得出了轻骨料经过预湿后的强度较普通混凝土要高。此外，提出了建设性的预湿轻骨料混凝土抗冻措施，与其相关的抗冻融原理仍需深入探讨。

英文摘要：

This paper clarifies the working mechanism of pre-wetted lightweight aggregate, then sum up the influence of various mechanicals properties of concrete after lightweight aggregate pre-wetted. It started with concrete workability, strength and frost resistance, summarized that strength of lightweight aggregate after pre-wetted will be higher than common concrete. Besides, it puts forward few constructive antifreeze measures, but the relative antifreeze theory is still need to be explored.
