Evaluation of Operational Properties of Composite Reinforcement Used in Concrete Structures

Abstract:

The paper is devoted to the study of composite reinforcement made of glass fiber and basalt fiber, in particular their operational properties under 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. Previous research indicated high alkali resistance of basalt fiber reinforcement, but there is a need in further studies. For the objective of the composite reinforcement that is used as flexible connectors for layer wall panels, a series of experimental studies. Research data have shown satisfactory performance study of flexible links.
