My fascination with concrete is continuing with a new discovery of spun concrete. These construction elements hold such a large density they almost have the same characteristics as steel. The concrete is placed into steel form and spun at 900rpm to consolidate the mix and create the extensive load bearing capacity. This discovery of mine is more related to structural engineering in a way but it poses the many architectural questions such as if concrete should be reconsidered for long span structures. Furthermore, the price of steel is set to rise 66% and will drive the need for improved concrete structures over steel. Below are some photos of the potential of spun concrete columns and beams.
