Characteristics of ferrocement thin composite elements using various reinforcement meshes in flexure

Abstract

This article focuses on the experimental investigation carried out on the characteristics of ferrocement thin composite elements using various reinforcement meshes in flexure. The parameters of this study include: the effect of the various kinds of reinforcement meshes (stainless steel meshes and E-fiberglass meshes); number of mesh layers and various mesh diameters with opening size as well as various kinds of mortar materials as matrix (cement grout mortar and polymer— cement grout mortar) on the first crack load; bending stiffness; ultimate flexural load; load—deflection behavior; crack characteristics; energy absorption capacity; and ductility index. The results clarify that the use of stainless steel meshes as reinforcement system in the ferrocement thin composite elements contributes significantly to the improvement of bending characteristics in terms of first crack load, bending stiffness, ultimate flexural load, energy absorption to failure, and numerous fine and well-distributed cracks with a smaller width than while using fiberglass meshes. The method outlined by ACI Building Code is used to compute ultimate moment capacities. The results obtained using this method are compared with the experimental results.

Reconstruction of flash flood victims lost residence utilizing lightweight sandwich composite technology

“…Studies also conducted on the contribution of ferrocement wire mesh reinforcement, with various sizes and volume fractions in direct tension, have also shown great improvement on the service and ultimate tensile crack behavior of the composite plates after sufficient warning, multi-cracking stage elongation, and distinct failure stage. [18][19][20] Cement grout mortar is designed for critical use, where high strength, non-staining characteristics, and positive expansion are required. It contains only natural aggregate and an expansive cementitious binder.…”

Development of sandwich composites for building construction with locally available materials

“…Modern buildings are generally constructed with materials such as Portland cement concrete, steel, timber, pre-fabricated gypsum panels, masonry units, polymer composites, and insulating foams [3][4][5][6][7]. Some indigenous materials used for building construction include adobe, rammed earth, cob, stabilized soil, stone, brick, concrete block, lime, gypsum, natural pozzolans, biomass ash, vegetable fibers (and their fabrics/ropes), bamboo and tree trunks/stems/leaves [8][9][10][11][12][13][14][15][16][17]. These indigenous construction materials are commonly used in the context of traditional building systems which provide basic shelter under regularly encountered load and environmental effects at minimum cost.…”
