This paper investigates the impact of varying humidity conditions on carbonation depth in hardened cement paste using a 3-dimensional microscale kinetic Monte Carlo (kMC) approach. The kMC algorithm effectively simulates process by capturing interplay between CO2 diffusion and relative at microscale, providing insights into macro trends that align with historical models. study reveals maximum is achieved levels 55 65%, where balance water optimized. At lower (<55%), observed. Conversely, higher (>65%), increased content impedes diffusion, resulting reduced for paste. model demonstrates parabolic relationship depth. Time series analysis shows Fick's law consistently followed, following x = k√t constant humidity. also breaks down event cycle which after an equilibrium (in terms rate events) H2O 75%, shift occurs dominance from reactive to transport processes 85%. These findings highlight importance influencing rates one hand demonstrate effectiveness approach simulating these complex interactions other hand.

Abstract Pyrometallurgical copper production is associated with high slag rates, typically ranging from 2.2 to 3.0 tons of per ton produced copper. Therefore, valorization necessary maintain a resource-efficient operation. An attractive application for these iron silicate slags as supplementary cementitious materials (SCMs), which effectively lowers the CO 2 emissions concrete. Although utilizing SCMs has been studied in previous work, scientific literature limited data on isolated effect composition inherent reactivity systems. In particular, no reports impact FeO/SiO ratio have presented publications. present study aimed isolate this parameter synthetic FeO–SiO –Al O 3 –CaO–MgO–Cr system. Since amorphous content pertinent SCMs, hot-stage confocal laser scanning microscope was utilized assess crystallization behavior at continuous cooling conditions. Furthermore, high-temperature rheological experiments were conducted measure viscosities relation behavior. The highlighted that depolymerizing by increasing poses increased demands rate avoid crystallization, consistent temperature structural changes slags. Rapid Reliable Relevant (R3) isothermal calorimeter experiments, assessing an SCM, showed ratios improves early expense seven-day reactivity, i.e., balance between degree polymerization and contribution silicon reactions.

Abstract The rapid rise in cement prices and the environmental consequences associated with production have raised an urge to look for alternative cement. There is increasing need recycle waste while minimizing impact. This research aimed develop affordable sustainable construction elements by using materials as a partial substitute goal was lower costs, reduce impact, all maintaining structural integrity of slabs. M15-grade mortar used experimental study, 15% replaced pozzolanic characteristics. A constant water–cement ratio 0.45 maintained throughout. specimens were tested, results compared control evaluate impact incorporation on performance, weight reduction, cost–effectiveness. Experimental testing revealed varying outcomes depending type material used. While inclusion generally reduced strength, brick powder retained 81.67% compressive ceramic tile 78.76% flexural strength control. Sawdust, however, caused significant reductions, limiting its potential use. key finding that led 6.13% reduction cost elements. All contributed considerable indicating lighter structures savings labor costs. study demonstrates integrating into ferrocement technology, paving way more sustainable, lightweight, cost–effective building materials.
