Abstract
Cement industry is one of the energy-intensive industries. Though Japanese cement industry has achieved top-class energy efficiency in the world, the development of the further energy saving technology is needed from the view point of global environmental protection such as the reduction of carbon dioxide and fossil fuel consumption. We reported low burning-temperature type clinker by adjusting of mineral composition previously. In this study, we carried out burning test of the low burning-temperature type clinker by actual kiln. As a result, the low burning-temperature type clinker was able to be burned in actual kiln, because the free lime was decreased less than 1％. Furthermore, it was estimated that the low burning-temperature type clinker was able to be sintered at 1,300 to 1,350℃, which was approximately 100 degrees less than the OPC clinker on the same condition. And the heat consumption rate was able to be reduced around 5％ compared with the OPC clinker. Next, we evaluated the cement manufactured by actual finish mill. As a result, we confirmed that the properties of the cement and the concrete were at the same level as OPC.
