Abstract
This paper describes the application of lightweight aggregate (LWA) in the creation of fire resistant composite. The effort of the project is the preparation of a light refractory material with good mechanical properties, which would reach technically economical solutions. We initially chose as lightweight aggregate Liaver, which in combination with chamotte aggregate represent the filler of composite. The following observations were focused on partial replacement of binding components with brick dust and its influence on the mechanical properties of the composite. After design process, test composite specimens were produced to determine hardened properties at standard age. On the 28 day were all the mixtures exposed to 105, 600 and 1000 °C. Lastly, the flexural and compressive strength tests were performed on the composite specimens to identify high temperature effect comparing to strength test results obtained from standard laboratory conditions.
