Intensification of Flexural Strength of Lightweight Foamed Concrete Via Woven Fiberglass Mesh Confinement

LFC possesses brittleness behaviour where its strength very poor and weak compared to normal concrete. However, due to its advantages, many researchers eager to find a new method or solution to enhance the strength of LFC. Even though, the LFC gain improvement but still there are side effects that has been faced. Thus, invention of textile fabric as reinforcing elements shows its potential use to boost the strength of LFC. Three different densities were designed which were 600 kg/m3, 1100 kg/m3, and 1600kg/m3 with fixed mix ratio, 1:1.5 for cement-to-sand ratio, and constant water at 0.45. Woven fiberglass mesh (160 g/m2) was utilized as confinement of LFC specimen with different number of layer(s) employed. Based on the results obtained, a confinement of 3 layers of woven fiberglass mesh showed significant results where the flexural strength of LFC gain enhancements of 372% (600 kg/m3), 258% (1100 kg/m3), and 332% (1600 kg/m3) compared to the control LFC.
