There has been great advances in concrete technology during the last one hundred years. The improvement in highstrength, high performance, fiber-reinforced, and other material and structural properties in concrete achieved earlier are now accepted as routine and various types of advanced concrete have been widely used. However, in spite of many of the improvements in concrete technology that have been made over the year, much remains to be developed about concrete technology, such as eco-friendly concrete, concrete mixed with advanced materials, maintenance, globalization, and standardization. |
