Abstract

Structure and properties of cement composite are time-varying characteristics, depending among others on environmental conditions. The key idea is a struggle for complex research of joint effect of physical, chemical and dynamic loads on the internal structure of cement composite and understanding the correlation between changes in microstructure and macro-scale properties. During the experimental program, specimens will be exposed to combined influence of freeze-thaw cycles, aggressive chemical agents and dynamic loading. The aim is to create a theoretical basis for design of effective cement composites meant to be used in severe environmental conditions. Two different concrete mixes are studied throughout the project: standard strength concrete used in load-bearing parts of bridges in the Czech Republic, used as a good representative based on consultations with designers and the ultra-high performance concrete.

Keywords: UHPC, FRC, dynamic loading, deicing agents, freeze-thaw cycles
