CEMENT CONCRETE WITH IMPROVED PHYSICO-MECHANICAL PROPERTIES BASED ON THE USE OF ACTIVATED SILICAFUME
This paper discusses the use of silica fume and methods of its activation for modifying the structure of cement stone and concrete based on it. With regard to any type of filler, in particular silica fume are relevant questions: how and how much to enter, what mechanisms are included in the process of structure formation, how much it costs to achieve the effect of modifying the structure and others.The formation of answers to these questions requires a systematic approach to the vision of the problem. Therefore, the role of microdisperse fillers in the processes of modifying the structure of cement stone and concrete on its basis should be considered in conjunction with other dimensional inclusions at different scale levels.
