摘  要:
通过在一定温湿度条件下研究不同强度等级引气混凝土干缩试验,探究含气量对不同强度等级混凝土干缩试验结果的影响、变化规律及机理,确定合理含气量范围,为有抗(盐)冻耐久性要求的不同强度等级普通混凝土配合比设计提供含气量参考数据。

摘  要:
An experiment was conducted to study the effect of air agent on drying shrinkage of different strength grades of concrete under certain temperature and humidity conditions. The changing regularity and mechanism were also discussed. The reasonable air agent range was determined, which could provide some references for the mixture ratio design of different strength grades of ordinary concrete in order to meet the demand of freeze-thaw resistance.
