Moisture Absorption by a Reinforced Polymer Composite (BFRP Rebar)

A model is developed for moisture absorption by rebar made of basalt fiber-reinforced polymer composite (BFRP), taking account of Fick diffusion, structural relaxation, and the design features of the rebar in the initial stages of climatic aging. The model is experimentally confirmed. The analytical...

Description
Summary:A model is developed for moisture absorption by rebar made of basalt fiber-reinforced polymer composite (BFRP), taking account of Fick diffusion, structural relaxation, and the design features of the rebar in the initial stages of climatic aging. The model is experimentally confirmed. The analytical solution may be used for kinematic approximation of moisture absorption by other reinforced polymer composites.
