Abstract

Purpose: This study aims to address sustainability challenges in construction by exploring the structural performance and environmental benefits of incorporating pozzolanic waste glass (WG) into ultra-high-performance reinforced concrete (UHPRC) beams. Design/methodology/approach: A comprehensive evaluation of UHPRC beams was conducted, incorporating varying ratios (10%, 20% and 30%) of WG powder alongside a consistent 0.75% inclusion of basalt fiber. The investigation encompassed the entire UHPRC production process, including curing, casting and molding, while evaluating workability and physical properties. Furthermore, the environmental impact, particularly CO2 emissions associated with UHPRC mixture components, was also assessed. Type K thermocouples were employed to analyze temperature dynamics during fabrication, providing valuable insights. Findings: The findings demonstrate positive implications for using pozzolanic WG as a cement substitute in UHPRC beams. Originality/value: This research stands out for its unique focus on the combined effects of incorporating recycled pozzolanic glass waste on the structural performance and environmental footprint of UHPRC beams.

Descriptive scope: 4 PCTA

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
