Evaluating the Influence of Palm Kernel Shell Ash on Ire Clay Geopolymer Concrete Cured at Ambient Temperature

There is an abundance of clay deposit in Ire Ekiti which can serve as geopolymer source material and Palm kernel shell exists a massive agro waste South Western Nigeria. This study evaluates the effect palm ash (PKSA) additive on compressive strength concrete. The objective to determine selected properties obtained concrete at room temperature. was burned 650oC for 2 hours furnace. Natural collected from manually pulverized, air dried calcined furnace 750o hours. prepared mixing ratio 1:2:3. constituents were (source material), 12M NaOH Na2SiO3 (ratio 2:5), river sand 12.5mm granite fine coarse aggregates respectively while PKSA 0%,7.5% 15% Clay content used preparing specimens cured ambient temperature till testing different maturity ages 7, 14 28 days. It generally observed that increasing percentage strongly improved gain with At days maturity, 7.5% addition by 166% 181% increase. highest 7.67N/mm2 day. Conclusively, are viable production. be practically applied like conventional structural work especially rural community where cement needs transported over kilometers. Also, performing well makes it cost effective compare most geopolymers require heating high recommended further durability should done.
