Pozzolanic activity of calcined halloysite-rich kaolinitic clays
Source abstract
Abstract
Abstract The aim of this study is to determine the pozzolanic activity of clays with high content of halloysite/kaolinite, and to evaluate the influence of halloysite/kaolinite ratio and halloysite morphology in the development of pozzolanic activity of the calcined clays. For this purpose, three different natural clays from Rio Negro Province, Argentine, were selected and completely characterized. After calcined at 700 °C and ground to 80% of particle size
