Gerd Portugall M.A.,Rüdiger Fiebigfter three heating steps at 200 ℃, 400 ℃, and 600 ℃. The two upper temperatures permit to accurately consider the kaolinite dehydroxylation, whereas the step at 200 ℃ considers the moisture state of the clay. The protocol of the test was optimized with an adequate sample mass of 10 g and finer than

https://doi.org/10.1007/978-3-531-94331-2t after grinding, calcined clays exhibit a strongly bimodal particle-size distribution, where the clay minerals concentrate mainly in the finer particle population. A significant increase in compressive strength at early age was observed in systems incorporating alkanolamines. The effect appears to

Institut für Baustatik und Konstruktiontion and thermogravimetric analysis indicate the potential of clay from two South African sources for clinker replacement in cement and concrete, showing that one source is very suitable, while the other is not.
