Bending resistance of high performance concrete elements [PDF]

open access: yesWIT Transactions on The Built Environment, 2008
Our previous research was focused on reactive powder concrete (RPC). In this article high performance concrete (HPC) will be analyzed. With high performance concrete both load bearing capacity and esthetics are combined to achieve superior structure. Due to lesser dimensions of walls and columns, space in high rise buildings is better utilized.
