description: The subject of the graduate qualification work is "The influence of superplasticizers on the plastic shrinkage of cement stone." The relationship between the plastic shrinkage of the cement stone and some additives including superplasticizers is the main topic of the work. The following goals were solved during the study:
1. Studding, generalization and analysis of the literature on the topic of the research.
2. Experimental study of the factors, which may have influence on the plastic shrinkage.
3. Recommendations development, which can help to reduce the plastic shrinkage.
The current state of the issue was analyzed. Various types of shrinkage, the most common methods for plastic shrinkage determination were considered, as well as the effect of various additives on it. Several experiments were conducted in order to achieve the goal of the study. The effect of some factors on the process of plastic shrinkage was determined by dint of observation, analytical and comparative methods
The main recommendations for reducing the plastic shrinkage were proposed based on the experiments and analysis of the literary sources.
