基于LCA的混凝土预制桩施工阶段碳足迹研究

Carbon footprint research of concrete precast piles based on LCA

建筑业发展迅速,项目规模大,耗能大,随着全球变暖以及气候不断恶化的相关压力越来越大,碳排放控制措施的要求也越来越高.为了使我们赖以生存的环境不再恶化,建筑业的可持续发展,建筑公司必须大幅度减少碳排放量.由于建筑行业涉及碳排放量之广,只能选取具有代表性的产品进行研究,选择研究施工阶段的混凝土预制桩产品,在全寿命周期理论的基础上找出它的碳排放规律.

The construction industry is developing rapidlywith large project scale energy consumption.With global warming and the pressure on climate change increasing,and carbon control measures are becoming more and more demanding.In order to make our living environment no longer deteriorate,for the sustainable development of the construction industry,construction companies must significantly reduce carbon emissions.Due to the wide range of carbon emissions involved in the construction industry,it is impossible for us to conduct comprehensive research,and only representative products can be selected for research.Therefore,this paper chooses to study the precast concrete pile products in the construction stage,and finds out its carbon emission rules on the basis of the whole life cycle theory.
