Abstract
[Display omitted]
► AAMK system has better acid, seawater attack, sodium sulfate resistance than PC. ► AAMK system has very good heat resistant up to 1200–1400°C. ► Polypropylene and short fibers increase AAMK flexural, strength and impact energy. ► Replacing 10% MK with FA or lime or 20% with calcite gave higher strength. ► MK and blended MK with steel slag can be used as repair materials.
The development of new binders, as an alternative to Portland cement (PC), by alkaline activation, is a current researchers interest. Alkali-activated metakaolin (AAMK), belongs to prospective materials in the field of Civil Engineering. This paper presents a comprehensive overview of the previous works carried out on the use of MK in alkali activation.
