Techniques of determination setting time of cement systems

Abstract

During concrete works in many cases one of the factors influencing manufacturing techniques of designs is the "setting time of cement system" parameter. In the work it is shown that today in different sources the term "end and beginning of setting" is interpreted in different ways. Methods of their determination are also various. So, it is possible to draw a conclusion that first of all it is necessary to concretize and tie the beginning and the end of a setting to internal processes in the cement-water system.
