Influence of Crisscross Fiberglass Strip on Axial Compressive Strength of Lightweight Foamed Concrete

Abstract

Concrete use as a building component is already associated with the global construction sector. Since extensive research on concrete has been conducted for many years, there is a growing interest among researchers to conduct studies to increase the capacity of concrete for use in the building sector. Lightweight foamed concrete is one of the cutting-edge solutions developed for lighter and more sustainable buildings. Although this type of concrete has several benefits, its strength is still viewed as being inferior to that of regular concrete. By limiting the LFC with a crisscross fiberglass strip, the authors of this work will demonstrate improvements in LFC behaviour in terms of its compressive strength (CFS). To examine its improvements, 3 different LFC densities were cast and contained with 1 to 3 layers of 160 g/m2 CFS. For this test, the cement-to-sand ratio was fixed at 1.1:5, and the water content was set at 0.45. The results revealed that the compressive strength of LFC confined with 1 to 3 layers of CFS increased by 153%, 97% and 102% were acquired for 600, 1100 and 1600 kg/m3 densities respectively. This demonstrates that the number of layers used affects how positively the confinement of CFS affects the compressive behaviour of LFC.

Influencia de la adición de fibra de vidrio AR sobre la resistencia a la compresión del concreto f’c 210 kg/cm2. Una revisión sistemática: 2020 – 2024

“…Este enfoque pionero no solo subraya la importancia de la innovación en materiales para la sostenibilidad en la construcción, sino que también abre nuevas perspectivas para la mejora en el rendimiento energético de los edificios. Mydin et al (2023), introdujeron la idea de reforzar hormigón ligero espumado con fibras de vidrio AR, destacando una mejora sustancial en las propiedades mecánicas, especialmente en la resistencia a la compresión. Analizando diferentes densidades del hormigón y variando el número de capas de fibra, los resultados evidenciaron incrementos en resistencia que podrían alcanzar hasta un 153%, dependiendo de la configuración de las capas de fibra de vidrio.…”
