Abstract: The chloride-resistant high performance concrete to be used is a basic technology to increase its durability in high chloride-ion environment. On the base of “Application technology guide for anti-seawater concrete of Guangdong province” (consultant version), the raw materials, mix proportion, placement of concrete, and the quality tests etc were discussed in detail.

Abstract: Guangzhou Xita Project uses a special exterior frame which consists of huge inclining concrete-filled columns. To ensure the engineering quality and select the suitable concrete-filled steel tube column structure, two concrete-filled steel tube column structure experiments have been carried out. To ensure the quality of the concrete-filled steel tube column structure experiment, the C100, C90 and C70 high performance concrete experimental research have been done specially, and the result of the experimental researches has been used in concrete-filled steel tube column structure sample successfully. The raw materials, mixture proportions and performance of the high performance concrete were discussed in this paper.
