Synergistic Effects of Waste Glass Powder, High-Frequency Ultrasonic Dispersion, and Liquid Glass Treatment on the Properties of Aluminum-Based Ultra-Lightweight Concrete

Materials, Год журнала: 2024, Номер 17(22), С. 5430 - 5430

Опубликована: Ноя. 7, 2024

This research investigates the impact of waste glass powder, high-frequency ultrasonics (HFUS) dispersion, and liquid treatment on aluminum-based ultra-lightweight concrete. Substituting up to 80% Portland cement with powder significantly delays hydration reduces compressive strength by 77%. However, applying HFUS dispersion for 60 s a mixture 30% substitution restored reference value 3.1 MPa. The combined enhanced 87%, increased density 32%, reduced prosody. Scanning electron microscopy revealed progressively denser matrix each treatment, highlighting synergistic effects these methods in improving concrete properties.

Development of a Recycling Process for the Recovery of Gypsum Stone from Stockpile Material

Recycling, Год журнала: 2025, Номер 10(1), С. 12 - 12

Опубликована: Янв. 16, 2025

Due to changes in the German government’s energy concept, amount of gypsum produced flue gas desulfurisation plants (FGD gypsum) will fall from 5 million tons per year 1 or less by 2038 at latest. As 2016, FGD accounts for 55% mix. The resulting raw material gap must be closed through innovative recycling concepts, such as processing existing mine dumps. process development aims achieve a calcium sulfate dihydrate content 85% and reduction stockpile volume 50%. main components stockpiles are form stone well clay minerals organic matter. Successful laboratory tests were transferred pilot scale jigging machine with dewatering screening. water is circulated throughout entire process. heavy fraction 76% when measured ICP OES 87% via thermogravimetric methods. Furthermore, pilot-scale dry screening on took place, up 1500 could processed. fluctuating weather conditions, quality was subject significant variations. Under optimal 60% feed recovered stone; however, nearly impossible during rain; therefore, combination downstream recommended.
