The potential for using recycled construction and demolition waste as a replacement for natural crushed limestone in the manufacture of precast concrete building blocks is being investigated at the University of Liverpool. Both the economic case and technical capabilities are being considered. Laboratory studies reported here have examined the use of both concrete and masonry derived waste materials, as a replacement for coarse aggregate and fine aggregate in block manufacture. Initial results include the development of a procedure for laboratory replication of industrial block manufacturing processes, together with trials with representative locally obtained materials to meet typical block specification requirements.
