Optimal Performance Assessment of Re-Recycled Concrete: Combining Water Absorption, Compressive Strength Using MOORA Technique
This work presents water absorption and compressive strength testing of re-recycled aggregate concrete with fly ash and silica fumes. Two different types of fly ash and silica fume were used in place of ordinary Portland cement. According to test results, the selected ratios of fly ash and silica fu...

| description | This work presents water absorption and compressive strength testing of re-recycled aggregate concrete with fly ash and silica fumes. Two different types of fly ash and silica fume were used in place of ordinary Portland cement. According to test results, the selected ratios of fly ash and silica fume added to the used concrete mixtures enhanced its strength and balanced the loss in water absorption, at water-cement ratio of 0.4. The paper also thoroughly examines the full life cycle and evaluates the reuse of recycled concrete, considering seven various mixtures, using multi-criteria decision-making, namely MOORA technique. This framework is analysed by evaluating essential performance factors, namely water absorption, technical aspect (compressive strength for both short and long durations), environmental factors (effects on human health, quality of ecology, global changes in climate, and source utilization), and financial considerations (price-related). The results indicate that utilizing re-recycled concrete aggregate presents a significant environmental impact reduction (up to 39 %), and cost savings (5-10 %) compared to traditional concrete. |
