本文以位于中东海湾地区的“填海造地”项目为背景和研究基础,该类型项目多采用大体积常态预制混凝土块建砌挡土墙,正面临海、背面挡土,作为海岸线永久存在,具有安装便利、稳定耐久、整洁美观的优点。出于美观和防海水长期侵蚀的要求,工程对该类型大体积常态预制混凝土块表面裂缝控制要求很高。本文就如何做好大体积常态预制混凝土块水化热温度控制与防止出险混凝土表面裂缝的问题开展试验研究,揭示大体积
Based on the “Reclamation and Land Reclamation” project located in the Middle East Gulf region, this project mostly uses large-volume normal prefabricated concrete blocks to build retaining walls, facing the sea and the back retaining soil. As a permanent coastline, With the convenience of installation, stable and durable, clean and beautiful advantages. For aesthetic requirements and long-term protection against seawater erosion, the project is very demanding on the control of surface cracks in this type of large-volume normal precast concrete blocks. This article on how to do a large volume of normal precast concrete hydration heat temperature control and prevention of concrete cracks on the surface to carry out pilot studies to reveal the large size
