摘要
在国贸三期主塔楼基础底板大体积混凝土工程中,通过合理的原材料选择和配合比优化,降低了混凝土的温升和收缩。足尺模型试验进一步表明配合比及施工、养护方法适用于实际底板工程中。在基础底板施工中,严格落实施工管理措施来确保混凝土的浇筑质量。
The hydration temperature rise and shrinkage of concrete were alleviated because of rationality of raw materials choice and proportion optimization in the third phase project of International Trade Center. Furthermore, the full-scale model test was carried out and showed that the concrete proportion and curing and construction methods can be applied in the massive concrete foundation slab of the main tower. Besides, in the construction of foundation slab, several management measures were executed strictly to make the concrete have a good quality.
