Abstract

Waste cathode ray tube glass has been formed into two different products which are spherical glass (GS) and crushed glass (GC). Since it is a new material that acts as a coarse aggregate in concrete production, the architectural and civil structures built with such concretes may face a risk of fire situations. Thus, it is important to analyze the behavior of concrete containing GS and GC after exposure to high temperatures. A series of experimental programs were conducted on mixtures of concrete containing GS and GC as coarse aggregates, which were subjected to high temperatures ranging from ambient temperature to 800 °C at exposure time of 1 and 2 h. Compressive strength, splitting tensile strength, mass loss, and X-ray diffraction were analyzed. Results show better compressive strength in concrete containing GS at temperature 200–600 °C. However, the use of GS affects the splitting tensile strength more negatively, compared to GC. But, at a temperature beyond 600 °C, the use of GC causing bubbles of glass appeared on the surface of concrete and toxic Pb was found in the crushed concrete paste.
