Abstract
In the function and performance of the cement and concrete, or in its time-dependent changes under the service environment, the distribution of elements, microstructure, and material transfer in the region of the nanometer digit take part deeply. In order to realize ″material design″ of the cement and concrete exhibiting the designated performance, and to realize a reliable concrete structure, it is indispensable to control its material transfer, chemical reaction, and structure formation in the region of nanometer under the manufacturing condition and the service environment. Recently, together with the development of science and technology, characterization methods in the region of nanometer were developed, and the analysis of the phenomena in the nanometer region using these nano-technologies, was being advanced. In this report, the application in the nano-technology in the field of cement and concrete research in recent years, is reviewed.
