Abstract—This paper describes an investigation of four-point
flexural behavior of geopolymer composite specimens which
made of textile reinforced geopolymer mortar. The two
different types of mesh (basalt and carbon mesh) and their
various aperture sizes were used as reinforcement. In this
experimental work, only two mesh layers (for each type of
textile) reinforced in geopolymer mortar are considered. All 21
plate specimens including reference specimens, each of size
360x180x20 mm3, have been tested for four-point bending
strength. Besides that, 15 samples with dimension 30x30x150
mm3 and 15 samples of diameter size 45 mm x length 90 mm
have been measured for evaluating the mechanical properties of
geopolymer mortar matrix. The results have shown that
geopolymer composite specimens with carbon meshes have both
the flexural strength and deflection higher than those with
basalt meshes. Besides, the decrease of aperture size of mesh
improves significantly the flexural strength due to increase
specified number of yarns.
Index Terms—Geopolymer, four-point flexural strength,
textile, compressive strength, carbon mesh, basalt mesh.
