dc.description.abstract | The feasibility of replacing quartz powder (QP) with liquid crystal display glass powder (LCDGP) in ultra-high-performance concrete (UHPC) matrix is discussed through the investigation of pozzolanic reactivity, packing density, compressive strength, pore structure, hydration behavior, pullout resistance, and direct tensile tests. The pozzolanic characteristics of LCDGP are verified by calcium hydroxide consumption and secondary hydrate formation. Although the replacement of QP with LCDGP reduces the packing density of the UHPC matrix due to the large particles of LCDGP, the compressive strength increases with LCDGP contents up to 50% thanks to the pozzolanic reaction. Excessive LCDGP contents of more than 50% degrade the mechanical properties due to packing density reduction. The fiber-pullout energy of the UHPC matrix with 50% LCDGP is 142% higher than that of the reference UHPC matrix. This high resistance en-hances the tensile performance of the ultra-high-performance fiber-reinforced concrete (UHPFRC) in terms of tensile strain capacity and energy absorption by 150% and 174% compared to the reference UHPFRC, respectively. | en_US |
