“…With regard to the fact that the diameter of the fibres did not change and the content of Zr was low it is possible to conclude that the precipitated products probably came from the surrounding environment of the concrete matrix. In comparison with actual processes in real concrete mixtures, earlier model studies [15][16][17][18][19][20][21][22]33] seem to have used too aggressive conditions.…”

“…% of ZrO 2 ), identified as Alki-Resistant glass (AR-glass) that demonstrated higher alkaline resistance just thanks to the addition of network-forming ZrO 2 . This type of glass is still being used for production of glass fibres for concrete mixtures, however, not even fibres made of AR-glass are completely inert to the strongly alkaline environment and they may corrode [15][16][17][18][19][20][21][22].…”

“…At present, there is no uniform standardized procedure for investigation of the interaction between the fibres and the concrete matrix. Many authors [15][16][17][18][19][20][21][22][29][30][31] in their works deal with various model studies evaluating mechanical changes or overall degradation of concrete, however, the chemical interaction of glass fibres in real concrete mixtures has been rather neglected. In this work we have assessed corrosion mechanisms of two types of AR glass fibres that differed by their final treatment (dispersable/non-dispersable lubrication) in two concrete mixtures.…”

“…The benefits for the use of GFRC are toughness, ductility, and reducing large cracks, when compared to normal reinforced concrete. Generally, alkali resistant glass (ARGlass) is selected for making GFRC to reduce the degradation of glass fiber due to alkaline content of cement [1][2][3][4][5] . The polymer latex admixture is commonly used to improve the flexural strength, workability, and toughness of GFRC [ 6] .…”

Abstract. The purposes of this study were to evaluate compressive strength, flexural strength, and drying shrinkage of Glass Fiber Reinforced Concrete (GFRC) applying different techniques and varying polymer content. Two groups of specimens were classified applying the techniques: sprayed and premixed methods. AR-Glass was used with fiber content of 3 to 4% by volume. GFRC was mixed and applied different techniques with proportions of Styrene Butadiene Rubber (SBR) content of 0%, 3%, 6%, and 9% by weight of cement. Compressive and flexural strength tests were performed at 1 and 28 days. Drying shrinkage tests were measured up to 98 days. The results obtained showed that increasing the SBR content showed a lower compressive strength of GFRC for both sprayed and premixed techniques. In the other hand, 28-day flexural strength results of GFRC for both premixed and sprayed techniques were found to increase with increasing SBR content. The GFRC mixes using sprayed technique exhibited flexural strength higher than the corresponding mixes using premixed technique because of the two-dimensional layer of fiber alignment for the sprayed technique. Increasing the SBR content exhibited the lower drying shrinkage of GFRC. At the age of 98 days, the drying shrinkage of GFRC using 9% SBR content was about 40% lower than that of GFRC using 0% SBR content.
