ABSTRACT

The effects of using glass powder as a partial replacement of cement on the flexural behavior of reinforced concrete beams exposed to elevated temperatures were summarized in this experimental study. The replacements of cement by glass powder used were 0% (control specimens), 5%, 10%, 15%, and 20% by weight of cement. Ten reinforced concrete beams with 150 mm x 180 mm x 1550 mm dimensions were cast and tested under a four-point loading, in addition to thirty cubes tested for the compression strength of the concrete representing the five replacement percentages. The beams and the cubes were divided into two identical groups, where the specimens of one of them were tested after being exposed to an elevated temperature of 600℃ for one hour. The results showed that the beams tested at laboratory temperature with glass powder replacement cement by 5% and 10% exhibited higher bending moment capacity values and lower ones with 15% and 20% replacement compared to the control specimens. The beams with 10%, 15%, and 20% glass exposed to elevated temperature showed increasing bending moment capacity and decreasing values for the beam with 5% compared to the control specimens. The results also showed that the initial cracking moment of beams with 5%, 10%, and 20% replacement decreased, and increased with 15% replacement by 50% compared to the control specimen for beams tested at laboratory temperature. However, the elevated temperature (E.T) had a varying impact on the initial cracking moment. The replacement of cement by 10%, 15%, and 20% W.G.P. increased the strength of the mortar by 9.2%, 15%, and 19%, respectively, at laboratory temperatures.
