Evaluation of Operational Properties of Composite Reinforcement Used in Concrete Structures

摘要

The paper is devoted to the study of composite reinforcements made of glass fiber and basalt fiber, in particular their operational properties in the aggressive alkaline lightweight aggregate concrete environment. Their thermal resistance being sufficiently less than that of the regular steel composites they may be used in three-layered building envelopes to provide enhanced thermal properties. However, there is lack of data and experimental results on the topic. The previous research indicated high alkali resistance of the basalt fiber reinforcement, but there is a need for further studies. For the realization of the composite reinforcement used as flexible connectors for the layer wall panels a series of experimental studies was carried out. The research data have shown satisfactory performance study of flexible links.
