Feasibility test and evaluation models to develop sustainable insulation concrete using foam and bottom ash aggregates

Temporal flowability evolution of slag-based self-compacting concrete with recycled concrete aggregate

“…The higher cement content of the CEM III mixes balanced the lower strength expected from using GGBFS (Yang et al, 2019), and even increased the strength: mixes III-0/F and III-0/L (55 and 62 MPa respectively) had 9.2 and 17.0% higher strengths than mixes I-0/F and I-0/L (50.5 and 53 MPa), respectively. The addition of fine RCA instead of siliceous sand decreased the compressive strength, mainly when using CEM I.…”

Harnessing Ash for Sustainable CO2 Absorption: Current Strategies and Future Prospects

“…Customization of Material Properties: Depending on the type of ash and the specifics of the CO 2 absorption process, it's possible to tailor the properties of the ash for specific applications in construction. For example, adjusting the porosity, particle size, or mineral composition of the ash can result in construction materials with desired characteristics, [184][185][186][187] such as increased strength or specific aesthetic qualities, and improved thermal / acoustic insulation properties which potentially improve thermal efficiency, potentially reducing energy consumption for heating and cooling in buildings.…”

Challenges in Foamed Concrete: Exploring Alternative and Sustainable Materials – A Comprehensive Review

“…Instead, finer particles can uphold and sustain these properties (94). Insights into the potential for utilizing alternative materials such as waste glass sand, fine marble powder, bottom ash, palm oil fuel ash, fine recycled concrete as a replacement in foam concrete (9)(10)(11)55,83,95,96). And the properties of foamed concrete were also investigated through the replacement of pulverized sand with foundry sand at various proportions (13).…”

“…The rate of these CO 2 emissions of can be reduced by using alkali-activated concrete instead of Portland cement as a binder. Studies on emissions from the cradle to the preconstruction were calculated based on Life Cycle Assessment (LCA) details in the literature, achieving a 55% and 80% reduction in carbon footprint (32,44,96,101,102,(104)(105)(106)(107)(108)(109)(110).…”
