Development of Practical and Cost-Effective Ultra-High-Performance Engineered Cementitious Composites Using Natural Sand and No Silica Fume

Daniel Game et al.

Summary: The aim of this study was to evaluate the feasibility of developing practical and cost-effective ultra-high-performance engineered cementitious composites (UHP-ECCs) using natural river sand and no silica fume (SF). The inclusion of SF generally had negative impacts on the mechanical strength and ductility of the composites, attributed to a worsening fiber dispersion. However, practical and cost-effective UHP-ECC materials were successfully developed using natural river sand and no SF.

Enhancing long-term tensile performance of Engineered Cementitious Composites (ECC) using sustainable artificial geopolymer aggregates

Ling-Yu Xu et al.

Summary: Artificial geopolymer aggregate is a new technology that aims to reduce the exploitation of natural aggregates and the burden of waste accumulation. This study utilized geopolymer aggregates to enhance the long-term tensile performance of high-strength Engineered Cementitious Composites (ECC). The results showed that GPA-ECC exhibited better tensile performance and ductility compared to conventional FSS-ECC. A cost analysis demonstrated the cost-efficiency and sustainability of GPA-ECC.
