Utilization of Sintered Sludge Ash with Different Mechanical–Thermal Activation Parameters as a Supplementary Cementitious Material: Mechanical Properties and Life Cycle Assessment of Cement-Based Paste

Materials, Journal Year: 2024, Volume and Issue: 17(16), P. 4101 - 4101

Published: Aug. 19, 2024

The proposal of sintered sludge cement (SSC) paste aligns with the low-carbon development goals building materials. However, there is a lack scientific guidance for preparation ash (SSA). Herein, this study systematically investigates influence mechanism mechanical–thermal activation parameters SSA on mechanical properties and life cycle assessment (LCA) SSC paste, conducts comprehensive evaluation using radar chart TOPSIS method. results show that increase in calcination temperature duration, compressive flexural strengths are improved, especially at 600 °C above, increasing by 57.92% 62.52%, respectively. longer time 1000 decrease its properties. addition significantly reduces LCA indicators paste. Specifically, 30% only contributes 8.1% to global warming potential. Compared calcination, have less sensitivity ball milling, prolonging hardly increases them. Based performance environmental impact, optimal obtained calcining 800 2 h milling 10 min. This can provide theoretical efficient material utilization dredged sludge.

Toward Viable Industrial Solid Residual Waste Recycling: A Review of Its Innovative Applications and Future Perspectives

Minerals, Journal Year: 2024, Volume and Issue: 14(9), P. 943 - 943

Published: Sept. 15, 2024

Industrial solid residual waste (ISRW) generated during and/or due to the making of energy, heat, and raw materials poses a major threat sustainable future its large production quantities complex characteristics. Especially improper disposal ISRW (e.g., coal ashes, municipal residue, biomass ashes) not only threatens human health but can also cause environmental hazards such as water, soil, air pollution, upsetting global balance. Given impacts well increasingly stringent regulations, lack landfills, economic constraints, more naturally friendly management strategies are being adopted for ISRW. While numerous studies in literature have considered various characteristics ISRW, complete appraisal entire practice, from disposal, is still lacking. This paper presents an overview making, features, traditional innovative managing tactics within context general legal framework. provides scientific review types, quantities, Additionally, orthodox ISRWs scrutinized sociological ecological standpoint, diverse techniques viable secure elucidated. culminates examination impact advantages policies based on legislation regulations. Consequently, this seeks elucidate extant practices few recent advancements pertaining ISRWs. it underscores ecological, sociological, issues engendered by proposes applications technologies.
