求翻译：In this study, precast concrete panel was developed by substituting blast-furnace slag for part of the unit weight of cement in the precast concrete mix. A life cycle assessment technique was used to estimate the carbon dioxide reduction. Carbon reduction in the materials as well as during the production phase was cons是什么意思？ 待解决

在这项研究，预制混凝土盘区通过替代blast-furnace炉渣在预制混凝土混合开发用一部分的水泥单位重量。 生命周期评价技术用于估计二氧化碳减少。 对材料的碳减少并且在生产阶段期间被考虑了。 Blast-furnace炉渣代替比率50， 60和70 wt.%用于开发预制混凝土盘区公式化。 蒸汽养护时间花费了作为可变物以值为8， 7， 6， 5和4 h。 结果表示，预制混凝土盘区公式化与blast-furnace炉渣替换的60%水泥单位重量满足了设计耐压强度标准，当蒸汽养护为6 h.是应用的。 二氧化碳放射低于那是33.8%控制混合，没有接受blast-furnace炉渣代替和8 h蒸汽养护
