Experimental Investigation of Four-Point Flexural Behavior of Textile Reinforcement in Geopolymer Mortar

Hiep Le Chi and Petr Louda
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.
