Effect of Alkali - Activated Natural Pozzolan on Mechanical Properties of Geopolymer Concrete

Abstract

As an alternative to Ordinary Portland Cement (OPC), the alkali-activated binders have been developed with better technical characteristics and more extended durability. The Alkali-Activated Iraqi Natural Pozzolans (AANP) could produce geopolymer cementation building materials and make them ecologically acceptable. The primary advantage of geopolymer cement is that it has a lower environmental effect that contributes to it. The engineering characteristics of geopolymer concrete produced using activated Iraqi natural Pozzolan are summarized in this research. The mechanical properties, modulus of elasticity, and ultrasonic pulse velocity of various concrete mixes were determined via experimental study. The impact of essential variables like water/binder ratios w/b % and curing conditions on the characteristics of geopolymer concrete have been identified using test data. The findings indicate that concrete and mortar produced with alkali-activated natural pozzolans have flexibility and moderate to high strength.
