Abstract

This diploma work deals with studies of fire technical properties of concrete exposed to high temperatures. Light concretes indicated LC, are cellular interstices and pores in the texture of concrete. They are used as constructional barrier, insulating construction and sometimes for constructional purposes when own weight of construction present conclusive her weighting. Starting with the history and ways of using the concrete, the thesis continues with introducing the basic characteristics of individual components and lightweight concrete itself. The diploma work also describes changes in physical and mechanical properties of lightweight concrete with fire exposure.
