high-contribution of strip glass waste in buckling- strengthening of slim glarc columns at once avoiding asr deterioration problems in concrete materials

The important thing about axially loading slender columns is buckling stability. however, very limited researches were found, especially using glass- reinforced concrete. an alkali silica reaction (asr) deterioration problem only occurs when particles are very fine. the utilization of glass as a particle was avoided, and bigger dimension of glass strip waste was utilized instead because cement cannot penetrate deep into the glass piece. a series of axial loading tests of glass-reinforced concrete (glarc) slim columns were carried out on arrangement types; glass strips, homogenous and randomly pieces reinforced to explore their buckling performance. all axial glarc columns capacity results were better than glassless columns reinforcement. the best reinforcement was longitudinal horizontal strip arrangement since they have consistent strength contribution hence allow the glarc columns to resist higher axial loads to avoid buckling failures. the tests results in a good performance and hence glarc columns have potential chances to be used extensively as structural compression members.
