Research on Performance of Cement with Kiln Dust-Activated Coal Gangue

Abstract:

The setting times and strength of cement substituting kiln dust-activated coal gangue for part of clinker was tested. The performance of sulphate resistance and restraining alkali silica reaction (ASR) of cement with 30% kiln dust-activated coal gangue was studied. The results indicate: the setting times of cement mixed with kiln dust-activated coal gangue is delayed and the early strength and later strength of cement with 10% kiln dust-activated coal gangue is improved to some extent, but the strength is reduced with farther increasing the content of kiln dust-activated coal gangue that replaces clinker, and obviously decreased when content of kiln dust-activated coal gangue is 30%; the performance of resisting sulphate of cement with 30% kiln dust-activated coal gangue is better enhanced; ASR is restrained to some extent.
