Synthesis of Alinite-Calciumchloroaluminate System Cement Using Solid State Waste

Alinite-Calciumchloroaluminate system clinker was synthesized from solid state waste. The raw materials were municipal incineration ash, sewage sludge, limestone and clay. ecocement was prepared by the mixing of synthesized clinker and optimum amount of gypsum and its hydrolysis characteristic was investigated. X-ray diffraction, conduction calorimeter and reflecting microscope were used to analyze structural and physical properties. The main phase of clinker were alinite, calcium chloroaluminate. $C_2$S, $C_3$S. From the results of hardening time, hydration reactivity of synthesized all samples was faster than that of ordinary portland cement.
