Abstract: Motivations for adopting recycled concrete as an aggregate source include the preservation of natural resources, effective utilization of a growing waste stream, and financial and energy savings. Although current New Zealand ...
Degradation of 2,4-Dichlorophenoxyacetic Acid in an Internal Circulation Three-Phase Fluidized Photoreactor Using N-TiO2/γ-Al2O3 Granule as Adsorbent and Photocatalyst
Publisher: American Society of Civil Engineers
Abstract: The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) was degraded in an internal circulation three-phase fluidized photoreactor (ICFPR) using nitrogen doping
Studies on the Thermal-Physical Treatment of Waste Concrete for Use in Lightweight Aggregate Concrete
Publisher: ASCE
Abstract: Demolition of buildings can generate large amounts of waste concrete, which if used effectively, can help reduce both the extraction of raw materials and carbon emissions. However, the presence of old cement mortar affects ...
