Abstract

Engineered Cementitious Composite (ECC) materials have high ductility, but their large consumption of cement is not in line with the current demand for green economy. In contrast, alkali-activated ultra-high ductility concrete (AUHDC) without cement aligns better with the concept of green construction. In order to better understand the performance of AUHDC, this study investigates the compressive strength of AUHDC based on the proportions of waste marble powder (WMP) in the powder, water-cement ratio (W/B), and sand-cement ratio (S/B). The results indicate that the amount of WMP should be minimized, as excessive WMP primarily acts as filler dispersed in the specimens, leading to lower compressive strength when a crack appears upon reaching the maximum load. A W/B of 0.34 is recommended, as lower W/B result in faster material setting, inadequate transport of the solution and ions in the specimens, poor uniformity, and rapid crack propagation, thereby reducing the strength of AUHDC. A S/B of 0.7 is found to be appropriate, as higher S/B leads to insufficient colloidal content and thinner sand coating. Under pressure, cracks directly penetrate the specimens, resulting in an increase in crack width and lower strength.
