Abstract
We developed an energy-saving cement for the purpose of decrease in the production energy of Ordinary Portland Cement（NC）. In the previous study（1）we found the possibility to reduce the production energy and to maintain the quality of cement, by increasing in the C3A content in clinker by 4％ and increasing in the admixtures content in cement by 5％. In this study we conducted production tests using small-scale plants which imitated commercial plants, and evaluated the production energy, property, and durability of the energy-saving cement. As the result we found that the production energy of the cement was decreased by 8.5％ compared to that of existing NC. The property and the durability of the energy-saving cement was equivalent to those of existing NC, except sulfate resistance. Moreover we conducted a construction test of concrete using the energy-saving cement, and we confirmed the test construction was finished as well as the construction using existing NC.
