Durability and environmental evaluation of rice husk ash sustainable concrete containing carbon nanotubes

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Фев. 5, 2025

The environmental issues in the construction industry have garnered considerable attention numerous studies. Ecologically sustainable green concrete addresses challenges industry. This study investigates impact of multi-walled carbon nanotubes (0–0.20%) rice husk ash (15%) to replace Portland cement. mechanical and durability properties four mixtures were analysed. Adding 0.1% 15% yielded satisfactory results, significantly improving compared without nanotubes. With addition 0.1–0.2% nanotubes, density elastic modulus increased, 28-d sorptivity decreased by 4.64–28.76%. resistance ability 111-d mass loss compressive strength increased 50.93–61.71% 25.28–48.47% under sulphate attack, respectively. 3.7–35.97% acid attack. And 120-d drying shrinkage improved 3.08–9.23%. predicted experimental results using Sakata, GL 2000, B3, ACI 209, CEB-FIP models. Sakata B3 provided most accurate early-stage long-term shrinkages with variation coefficients 0.13–0.33 0–0.05, Moreover, sustainability containing was evaluated, its friendliness confirmed. Thus, viability contributes construction.

Valorization of recycled concrete powder, clay brick powder, and volcanic pumice powder in sustainable geopolymer concrete

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Апрель 1, 2025

Abstract The use of recycled powder as a binder in geopolymer concrete (GPC) represents promising approach to reducing construction waste and promoting the production sustainable materials. This study examines impact (RCP), clay brick (CBP), volcanic pumice (VPP) on mechanical, durability, thermal properties GPC with fly ash slag under water curing. Key mechanical properties, including compressive strength (CS), splitting tensile strength, flexural were evaluated, while durability was assessed through absorption, penetration, resistance sulfate acid attacks. performance tested by exposing samples elevated temperatures 200 °C, 400 600 °C. Results demonstrated that incorporating 25% RCP enhanced CS 14.88% at 28 days compared control mixture, although higher replacement levels (50% 75%) led reduced due increased porosity. Similarly, CBP substitution resulted 21.12% increase CS, declines observed levels. Conversely, VPP decreased 8.68% days, further significant reductions its high Sulfate testing 5% MgSO₄ solution showed minimal mass loss for mixtures (0.3–1.2%) moderate (5.7–29.6%). exhibited low (0.3–1.7%) (8.7–15.8%), experienced highest losses (1.36–3.4%) (20.5–31.3%). SEM analysis revealed denser microstructures, which contributed their stability. Generally, optimizing RCP, CBP, improves pore structure, GPC. Among materials, superior acidic environments, excelled stability, demonstrating potential producing durable concrete.
