Jan 01, 2008· Fuzzy controller of cement kilns has been one of the first successful applications of the fuzzy control in industry. In 1978, Holmblad and Ostergaard used the first fuzzy controller for a complex industry process, cement kiln. They saw that the results were much better than when the kiln was directly controlled by human (Wang, 1994).
Microstructural formation was related to the strength values of cement mortars, in the scope of this study. The established relationship was modeled by using fuzzy logic prediction model. Pore area, unhydrated part and hydrated part of cement mortars were addressed for microstructural investigations. These parameters were taken into account as area ratios for each.
