The site application with 700kg/$\textrm{cm}^2$ high strength concrete

700kg/$\textrm{cm}^2$ 고강도 콘크리트의 현장적용

A successful site application with 700kg/$\textrm{cm}^2$ ultra-high strength concrete was made by research team of Daewoo Institute of Construction Technology in Jinhae. Trial mixings of concrete, the productivity of batcher plant, the elapsed time and the pumpability had been investigated for the site condition, before the site application. As results, the efficiency of production by automatic batcher plant systems was improved and the method of quality control was estabilished for the security of fluidity due to the elapsed time, the pumping and consolidation and so on. The concrete strength cores as well as cylinders was showed more than 700kg/$\textrm{cm}^2$ for the required age. And this study would be provided valuable data base for the practical utilization of high strength concrete. Further, this study would be given new possibilities of high rise RC constructions.
