摘要
采用青林湾大桥实际应用材料进行了补偿收缩混凝土的试验,并对试验结果进行分析,给出外掺剂的最佳掺量,并指出掺入外掺剂的混凝土具有优良的工作性能,且能较好地满足宁波青林湾大桥的设计及施工要求,提高工程质量。
This article takes experiment of shrinkage-compensating concrete by using material practically used in construction of Qinglin bay Bridge, and analyzes results of the experiment. It also gives the best parameter of additive agent. It points out that the concrete which be added with additive agent bears gcod property and could meet requirements of Ningbo Qinglin bay Bridge and thus improve the project＇s quality.
