Glass Fibre Reinforced Concrete Use in Construction Eng
Glass-fibre reinforced concrete (GRC) is a material made of a cementatious matrix composed of cement, sand, water and admixtures, in which short length glass fibres are dispersed. It has been widely used in the construction industry for non-structural elements, like façade panels, piping and channels. GRC offers many advantages, such as being lightweight, fire resistance, good appearance and strength. In this study trial tests for concrete with glass fibre and without glass fibre are conducted to indicate the differences in compressive strength and flexural strength by using cubes of varying sizes. Various applications of GFRC shown in the study, the experimental test results, techno-economic comparison with other types, as well as the financial calculations presented, indicate the tremendous potential of GFRC as an alternative construction material.
Performance of Isolated Footings Reinforced Randomly by Glass Fiber
Fiber glass reinforced concrete (FGRC) is used form any structural elements due to its high mechanical properties, particularly flexural strength. As the concrete crack forming process accelerates and the probability of sudden fractures increases. There were various methods to eliminate this weakness of concrete. One of most common methods was employed of randomly distributed fiber. In this paper, two types of isolated footings were utilized, square and rectangular shape reinforced by a fiber glass with a length of 18 mm and having a rate of (0.20, 0.30, 0.35, 0.40, 0.50 and 1.00%) of weight, to experimentally investigate the tensile and fatigue properties of footings The results of FGRC were compared with the reinforced steel concrete. The results revealed that FGRC has a positive effect on the tensile and fatigue properties of isolated footing, especially with higher percentage of used fiber glass.
The strength of thin composites of finite width, with brittle matrices and random discontinuous reinforcing fibres
A new theory is proposed for the estimation of the tensile strength of a two-dimensional composite with a brittle matrix and randomly orientated discontinuous elastic fibrous reinforcement. The estimate is made by integrating the strengths of all fibres that cross a transverse crack. It is necessary to know the relationship between the length of embedment of a fibre and the force needed to break it or pull it out. No assumptions are made about the shape of the cross section of the fibre or about the magnitude or distribution of bond stresses. An important feature is the allowance made for the loss of effectiveness of fibres cut by the edges of a tensile specimen of finite width.
