Assessment of mechanical properties and sustainability of cement-based and geopolymer-based reef limestone aggregate concretes

Key Points

• Geopolymer-based concretes show enhanced sustainability compared to traditional cement-based ones, offering potential eco-friendly alternatives.
• Mechanical properties of geopolymer concretes demonstrated superior compressive strength, reaching up to 40 MPa after 28 days.
• Assessment utilizes standardized mechanical testing methods to evaluate performance across different mixtures and compositions.
• Significant differences in sustainability highlight the need for greener construction materials; further comparative analyses are warranted.
