Plasticizer Type Influence on HCP Radiation Resistance

Abstract

In recent years, the variety of such additives with different functional effects has reached an unprecedented amount. Of greatest interest is the use of functional additives in the construction of modern nuclear power plants, since this directly affects the quality and timing of construction. However, exposure to radiation is a unique environment, and radiation-induced changes in concrete have only been little studied. Each type of plasticizing additives has its own chemical structure and mechanism of action, therefore their influence on concrete composition will be different. Judging by the existing experimental data on various additive research, it can be concluded that the study of the effect of the chemical structure or type of the plasticizer on radiation resistance is of significant practical interest for modern construction. In the current work, the analysis method using DSC is adopted as a research technique. Since the study of plasticizing additives based on polycarboxylate ethers was carried out in the recent work, to analyze the effect of the type of the plasticizing additive, in the current work the plasticizing additives based on naphthalene formaldehyde, melamine formaldehyde and lignosulfonates were chosen as the object of study.
