Site application of alkali-activated slag concrete in a Chinese building

Kai Yang and Muhammed Basheer of the University of Leeds, Changhui Yang of Chongqing University, China, Jingjie Zhang and ©ɐȁ§Ɗȁ of Chongqing Construction Science Research Institute, China and Yun Bai of University College London report on the first cast-in-situ structural application of alkali-activated slag concrete in a building in China. Attention was given to quality control of raw materials and concrete, construction procedure and assessment of both the consistence and strength. This project has demonstrated that the quality and cost involved could be controlled with a detailed working plan. It has also been found that the alkali-activated slag concrete has the potential to be used in cold-weather construction, as the ambient temperature during the construction of the demonstration building was quite low, sometimes below 5°C
