The improper curing of concrete can seriously affect its hardened properties. However, a large quantity water is required to cure after casting. Water valuable resource and availability posing particular challenge in the Middle East including Kurdistan region Iraq. Self-curing may be considered novel method that inside mix retained so hydration continue without supply additional Therefore, aim ...

In this study we report X-ray diffraction and dilatometry results of metakaolin (MK) geopolymers produced with Na, K, Rb or Cs silicate solutions, and cured for 7 days and 5 years, with the aim of identifying variations in structure and performance (dimensional stability at elevated temperature) over an extended curing period at ambient temperature. All of the geopolymers studied are mainly X-r...

Abstract Geopolymer concrete (GPC) reduces the environmental impacts of conventional Portland cement concrete, therefore, this research aims to investigate compressive characteristics GPC by utilizing readily available industrial waste i.e., coal based Flyash in Khyber Pakhtunkhwa province Pakistan. For preparation GPC, Na 2 SiO 3 was used as an activator. After specimens, their were investigat...

Alkali-activated binders (AABs) are developed through the activation of aluminosilicate-rich materials using alkaline reagents. The characteristics AABs a novel dry-mixing technique incorporating powder-based reagents/activators extensively explored. A total forty-four binder mixes assessed in terms their fresh and hardened state properties. influence mono/binary/ternary combinations supplement...
