Özet
Autoclaved aerated concrete (MC) is a construction material obtained by being pore-forming of the mixture prepared with finely crushed siliceous aggregate lime, water and limestone with the addition of aluminum powder and being cured with steam cure (autoclave). MC is a widely used material today in the constructions as a material that is very light compared to concrete or conventional stone material and that has high insulation properties and fire-resistant light construction material. In this study, the effect of fiber type and size in the production of MC on compressive, flexural strength and thermal conductivity values has been investigated. In the study, G2/04 class having 400 kg/m(3) density of MC production used for wall element and commercially produced was taken as a reference. Fiber types were substituted for an equal amount of aggregate and MC samples were produced. The mechanical properties and thermal conductivity values as well as microstructural features of the sample produced were examined. The samples produced were waited at the temperature of 60 degrees C in 4 h-cure, then they were subjected to the cure at the temperature of 180 degrees C, at the pressure of 11 bar and in an autoclave for 6.5 h. As well as the mechanical properties of the samples produced and thermal conductivity values, their microstructural features were also examined. In the study, it was seen that fiber was supplemented instead of quartzite increased flexural and compressive strength of MC and carbon fiber reinforced MC gave the best flexural and compressive strength compared to fiber types.
