Effect of Chloride on Tensile and Bending Capacities of Basalt FRP Mesh Reinforced Cementitious Thin Plates under Indoor and Marine Environments

Abstract

This paper presented a durability experimental study for thin basalt fiber reinforced polymer (BFRP) mesh reinforced cementitious plates under indoor and marine environment. The marine environment was simulated by wetting/drying cycles (wetting in salt water and drying in hot air). After 12 months of exposure, the effects of the chloride on the tensile and bending behaviors of the thin plate were investigated. In addition to the penetration of salt water, the chloride in the thin plate could be also from the sea sand since it is a component of the plate. Experimental results showed that the effect of the indoor exposure on the tensile capacity of the plate is not pronounced, while the marine exposure reduced the tensile capacity significantly. The bending capacity of the thin plates was remarkably reduced by both indoor and marine environmental exposure, in which the effect of the marine environment is more severe. The tensile capacity of the meshes extracted from the thin plates was tested, as well as the meshes immersed in salt solution for 30, 60, and 90 days. The test results confirmed that the chloride is the reason of the BFRP mesh deterioration. Moreover, as a comparison, the steel mesh reinforced thin plate was also tested and it has a similar durability performance.

Investigation of the Coefficient of Linear Temperature Expansion of Composite Rods and Heavy Concrete

“…It is shown that the systems reinforced with basalt fibers have high resistance to these aggressive influences. A similar comparison is made in [11][12][13] and it is shown that the tensile, bending and shear strength limits and modulus of elasticity are not inferior to GRP in their resistance. In [14][15][16] the resistance of basalt-plastic materials to low, high temperatures and thermocycles has been investigated and the stability of these materials to the specified effects has been shown.…”

“…Advantages of polymeric materials reinforced with basalt fibers in terms of mechanical parameters, cost, resistance to aggressive environments, biological resistance are discussed in a number of works [6][7][8][9][10][11][12][13][14][15][16].…”

“…A topical issue in the use of BPAs in construction is the confirmation and justification of the preservation of properties at a high level in the process of long-term operation in a variety of climatic conditions. However in all listed works [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] there is no information on change of properties of construction machinery under the influence of natural climatic conditions of different zones.…”

Influence of moderately warm and extremely cold climate on properties of basalt plastic armature

“…It is shown that systems reinforced by basalt fibers have high resistance to these aggressive influences. A similar comparison was made in [5, 6, 7] and it is shown that the ultimate tensile strength, ultimate bending strength, ultimate shear strength, and moduli of elasticity in tension, bending and shear are not inferior in their durability to the glass-reinforced plastics. In [8, 9, 10], resistance of basalt plastics to the action of low, high temperatures and thermal cycles was studied and stability of these materials to the indicated effects was shown.…”

“…The basalt plastic armature of periodic profile (BPA) is used in construction of industrial structures, electric power facilities, in road construction, in light arched building structures, to which demands for climatic and corrosion resistance are made. Advantages of polymeric materials reinforced with basalt fibers are discussed in a number of works [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] according to mechanical parameters, cost, resistance to aggressive environments, and biological resistance.…”
