Recycling of geopolymer concrete - ScienceDirect

Dec 30, 2015  The available literature on concrete recycling with respect to GPC is limited only to the use of recycled concrete aggregate produced from OPCC concrete debris in a geopolymer concrete matrix , . GPC is a relatively new material with a currently slow adoption rate and thus very little GPC is expected to be available in short term for recycling.
