Calcium aluminate cement shows superior performance, road applications, industrial floor applications, refractory applications requiring high temperature resistance etc. in areas like. In this study, lightweight concrete samples with calcium aluminate cement were produced by using 3 different methods: hydrogen peroxide, hydrogen peroxide +2mm expanded perlite and only foam. Lightweight concrete mixes were poured into 4040160 mm prisma and 6025 mm measure cylindrical molds and cured at 23 C and 90% relative humidity after being removed from the mold. Dry density, bending-compressive strength, capillary water absorption and thermal conductivity tests were conducted on the hardened lightweight concrete samples. In addition, the effects of mixture parameters such as hydrogen peroxide usage ratio, expanded perlite usage ratio on sample physicomechanical properties were analyzed. According to the findings obtained from the experimental results, the physico-mechanical properties of lightweight concrete samples were compared and the type of sample with optimum properties was determined. As a result, in this study, light concrete samples were produced using by calcium aluminate cement, which has a dry density of 269-348 kg/m3, compressive strength of 245-464 kPa, flexural strength of 155-375 kPa and thermal conductivity of 0.068-0.092 W/mK.
