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
This article examines the pozzolanic performance of Portland cement blended with ground granulated blast furnace slag (GGBS), and bagasse Ash (BA). The effect of different water to binder ratios in cementitious composites is analyzed through the hydration process of the proposed mixes using thermodynamic modeling and experimental technique. The hydration of the composites involves the formation of Portlandite, calcium-silicate hydrate (C-S-H), ettringite and monosulfoaluminate (AFm) at 28 days. The results of thermodynamic modeling are compared with compressive strength, dry density, Frattini, lime saturation and strength activity index tests. Portland cement blended with GGBS attained better pozzolanic activity with 0.4 and 0.5 water to binder ratios than admixed BA under all types of testing. The compressive strength of GGBS blended mixes with water to binder ratios of 0.4 and 0.5 attained 51.5 MPa and 44.458 MPa, respectively, at 28 days, which are 20.778% and 12.128% higher compared to BA blended mixes.
