RISAlkali-Activated Slag Concrete with Recycled Aggregate: Long-Term Performance
Publisher: ASCE
Abstract: This paper evaluates the long-term mechanical properties (up to 1 year) of alkali-activated slag concrete produced with recycled coarse aggregate (AAS-RA) and natural coarse aggregate (AAS-NA). The AAS-RA achieved a ...
Durability Assessment of Alkali-Activated Concrete Exposed to a Marine Environment
Publisher: ASCE
Abstract: This study investigated the performance of two alkali-activated concretes (AACs) subjected to marine exposure for 2 years. The AACs were synthesized from a low-calcium Class F fly ash (FA) and a blast-furnace slag. ...
Systematic Analysis of the Impact of Data Preprocessing Techniques on Machine-Learning Model Performance: A Case Study of a Compressive Strength Prediction Model for Geopolymer Concrete
Publisher: American Society of Civil Engineers
Abstract: Geopolymer concrete (GPC) is emerging as a sustainable alternative to ordinary Portland cement (OPC) concrete. However, developing mix designs for GPC presents unique challenges due to the variability in fly ash properties ...
Systematic Review on Alkali-Activated Binders Blended with Rice Husk Ash
Publisher: ASCE
Abstract: Production of alkali-activated binders is a developing research field that utilizes industrial/agricultural by-products and solid waste for the development of sustainable concrete. This paper comprehensively reviews the ...
Evaluating the Environmental Performance of Blended Cement-Based Concrete: A Comparative Life-Cycle Analysis to Derive an Environmental Score
Publisher: American Society of Civil Engineers
Abstract: The production of portland cement, particularly clinker, is a major source of CO2 emissions in concrete manufacture. Blended cement has emerged as a low-carbon alternative to improve sustainability, but the lack of comparative ...
Optimization of Enzyme-Based Soil Stabilization
Publisher: ASCE
Abstract: Enzyme-based soil stabilizers have been successfully used in ground applications for the last 30 years. However, the successful application of a given enzyme-based additive is case specific and depends on soil type, ...
