A new generation of concrete in civil engineering

摘要

This paper presents current tendencies in the state-of-the-art in research on technology development in a new generation of cement-based concrete. The classification of such concrete and its characteristic physical properties that have been difficult to achieve up to the present time for so-called ordinary concrete are presented. The examples of mixture ingredients and proportions are given for the new concrete. It is particularly of high strength and hither to unobtainable resistance to environmental impact are highlighted. Such features increase the application possibility of concrete structures in the most difficult conditions and in many cases they are competitive with steel structures. Examples of the applications of the new concrete in different branches of technology are given. Attention is paid to the necessity of codifying at least at the level of Eurocode rules of the examination and design of the material and structures made from high strength concrete (HSC).
