Evaluation of the Mechanical Properties of Lightweight Foamed Concrete at Varying Elevated Temperatures

Lightweight foamed concrete (LFC) made from cementitious materials with air pores entrapped in the matrix by mechanically entrained foam mortar slurry has several economic and environmental benefits. Most recently, LFC been heralded as next generation of lightweight construction industry because its versatility technological advancements. Owing to many desirable qualities, including low density, cost, thermal conductivity, dimensional change, amazing load-bearing capacity, great workability, weight, it is considered an adaptable flexible material. Given that a brittle building material since fire among most frequent catastrophes affect structures, crucial consider structural performance subjected high temperatures. Hence, this experiment attempts ascertain effect varying elevated temperatures on LFC’s strength properties. Three densities 500, 1000 1500 kg/m3 were prepared. The specimens exposed predetermined ambient 20, 100, 200, 300, 400, 600, 700 800 °C, samples assessed for porosity, compressive flexural strengths. outcomes investigation showed that, regardless loss stiffness happened primarily after 90 °C. This shows underlying process triggering internal cracking, transpires when water grows dissolves porous medium. Lowering dry density diminishes rigidity. LFC-normalized stiffness–temperature relationships various densities, other hand, are very comparable. From temperature up until 400 all exhibit moderate constant stiffness. Nevertheless, decline faster 600 °C or at which point loses ability support any given weight. study emphasized necessity more codes’ provisions take into consideration constituent types cutting-edge technologies.
