To ensure sufficient reaction between concrete and carbon dioxide, carbon dioxide was added during the concrete mixing process. The study involved varying water-to-cement ratios (W/C), carbon dioxide pressure, and carbon dioxide concentration to crea

Concrete mixtures have an optimized mix design in view of attaining desired properties. However, after mixing, during further processing, it is typically not possible to further adjust the performance of the fresh and hardening concrete. A new and em

Addressing the scarcity of research on the residual expansion deformation of steam-cured concrete and its underlying factors, this study introduces a testing apparatus to characterize the internal stress in fresh concrete during the thermal treatment

Measuring the flow properties of fiber-laden fresh concrete poses a substantial challenge because not only the fraction of fibers but also their orientation process during the measurement influence the measured quantities. Numerical simulations of th

Abstract Self-compacting concrete (SCC), which flows under its own weight without being compacted or vibrating, requires no outside mechanical force to move. But like normal concrete, SCC has a brittle character (weak in tension) that causes sudden c

Processes occurring during concrete curing such as settlement, hydration, and early-age shrinkage cracking define its long-term performance. These processes result in the emission of elastic waves which contain characteristic information about them.

This review shows that global sugarcane production reached 0.012 billion metric tons of bagasse ash (BA) in 2018, with Brazil, India, and China as top three producers. This industrial BA has a high loss on ignition (LOI). Hence, further burning at 80
