EN Purpose: Weathering effects on the weight and shrinkage strain of GFRC composite material are experimentally investigated in this paper. The five samples with different percents of glass fibers are chosen to test the effectsof humidity on the deformation of GRC. Design/methodology/approach: These samples are exposed to the environment with different humidity. Findings: GRC was considered for the fabrication of 30m high telecommunication towers. Other structural suchas pedestrian bridges, roof elements and floor slabs were also studied. Practical implications: The experimental results show that the effect of weight change on strain at dryenvironment is more significant than wet environment, and GFRC with 5% of glass fiber obviously reduces theweight change and strain. Originality/value: In this paper the variation of absorbing water rate, edabsorbing water rate, shrinkage strain, weight change, temperature, expansion strain and temperature change rate of GRC material with time wasexperimentally investigated.
