Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
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 enhances 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.
