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.
Structural application of GRC in telecommunication towers
Abstract Glass-fiber reinforced concrete (GRC) is a material made of a cementitious matrix composed of cement, sand, water and admixtures, in which short length glass fibers are dispersed. It has been widely used in the construction industry for non-structural elements, like facade panels, piping and channels. In this paper, the results of a research project are presented where this material was applied to the fabrication of structural elements, namely 30 m high telecommunication towers. Here, the lightness and tensile strength advantages of the GRC were associated with carbon and stainless steel reinforcement, leading to an innovative material with high durability.
Improved properties of GRC composites using commercial E-glass fibers with new coatings
Abstract A study was carried out to evaluate the action of a new 15CaO–15BaO–20SiO2–50TiO2 coat on long-term durability of glass fiber reinforced cement. Compressive strength, flexural strength and drying shrinkage were measured. Significant improvement was observed and four reasons were given to explain it. The results testify further the effectiveness of the alkali resistance of the new coat.
