Abstract
The environment surrounding the cement industry has greatly changed in these 30 years. In addition to the significant decrease in domestic demand for cement, we have been faced with such new challenges as CO2 emissions and other environmental issues, many natural disasters occurring around the country and recoveries from them, and severe shortage of human resources. With a special focus on cementitious materials, this paper summarizes the technologies developed during this period and the future topics, including use of more wastes and by-products in the cement production, development of new cements, enhancement of functionality and durability of cement and concrete, investigation of new deterioration phenomena, and development of analysis techniques.
