原始语种摘要: Abstract(#br)Use of metakaolin as a cementitious supplementary material has found interesting applications during recent years. This interest is in part due to the technical advantages and related to environmental and energy issues, particularly in CO 2 gas emission challenges in another part. However, kaolins that have effective pozzolanic activity and meet the desired requirements are still being studied. Current research aims to investigate calcination of two types (from Zonouz and Khorasan districts, Iran) of kaolin at temperatures of 600-850°C for production of metakaolin with pozzolanic activity. The samples were analyzed using Particle Size Distribution (PSD), BET, DTA/TG, XRD, SEM, and FTIR techniques to specify the mineralogical composition and extent of...
