Comparative Study of the Chemical Degradation Effects on Polymer Concrete with Limestone Aggregates

Abstract:

The objective of this paper is to investigate the influence of chemical degradation effects on polyester polymer mortar (PM). For this purpose, different dosages of siliceous and limestone PMs and natural stone specimens were exposed to representative degradation agents. Since the motivation for the research was to determine the durability of polymer mortar, it was considered important to simulate the types of aggressive environments that could conceivably be brought into contact with the material in domestic and industrial environments. In this paper, the possible variation of the surface aspect, water absorption and mass of the tiles after being immersed the specimens in different solutions, was measured and considered by visual observation and optical microscopy. As a conclusion PMs stability is strongly affected by the adhesion between matrix and aggregates at interface, and it is also dependent of the nature and packing level of aggregates.
