Bending Behavior of Fiberglass Textile-Reinforced Thin Geopolymer Mortar Panels

Abstract

Textile-Reinforced Mortar (TRM) or Textile-Reinforced Concrete (TRC) can produce novel structural techniques in civil engineering fields. The current study experimentally investigated the bending behavior of thin geopolymer mortar panels reinforced with Fiberglass Textile Grids (FGTG). The experimental work totally consisted of twelve panel specimens divided into two groups; each group included six specimens. The first specimen of each group was unreinforced, whereas the rest of the specimens were reinforced with a different number of grids; however, each group’s molarity of NaOH solutions was different. The results showed that the flexural strength and compressive strength of geopolymer mortar were significantly increased with the increment of molarity of NaOH solutions by 33 %. Textile reinforced geopolymer mortar (TRGM) panels showed deflection hardening behavior and multiple cracking. The deflection values at the same load levels were decreased when the number of grids and the molarity of NaOH solutions were increased. For TRGM specimens, in addition, the difference in molarities of NaOH solutions depicted a clear influence on the number and propagation of cracks. The toughness values of TRGM specimens were importantly enhanced with the increase of the FGTG reinforcement ratio.

Experimental and Numerical Assessment of Bonding Between Geopolymer Concrete and CFRP Sheet Using NSM Techniques

“…and many research has been conducted to evaluate the behaviour of gyopolymer concrete for structural applications [14][15][16][17]. Geopolymer morter has also been used with fibre textile grids for strengthening of concrete structure [18]. The rehabilitation and strengthening of geopolymer concrete structures will encourage the use of this type of concrete for its contribution to the reduction of environmental impact.…”

Testing the Properties of Cement and Gypsum Boards Reinforced with Nonwoven Fabrics Made of Waste and Recycled Fibres

“…Particularly favorable results were obtained in the case of tanning sheep's wool. The introduction of fibers into cement boards improves thermal insulation properties, reduces the weight of the element, reduces the risk of cracking, and improves the acoustic insulation of the partition [4,5]. It is expected that similar properties should be exhibited by needle-punched nonwoven due to the consolidation of loosely bound fibers.…”
