Title: Use of Industrial and Agricultural Wastes in Construction Concrete

Abstract:This work investigated the effects of Class F fly ash (FA), coconut husk ash (CHA), and rice husk ash (RHA) as cement replacements at various proportions on the workability, setting time, compressive strength, and pullout strength of concrete. Concretes containing partial replacement of cement by 20 and 40% FA and 10, 15, and 20% CHA and RHA were investigated. The results revealed that FA, CHA, and RHA can be used as replacements for cement in concrete production to produce sustainable and ecological products. The mixed composition of 20% FA and 20% RHA had 15.3% greater compressive strength than that of the reference composition after 180 days, while a slight reduction in this parameter was observed in FA-CHA combinations. FA and RHA mixtures showed the highest compressive and pullout strengths for all aging times tested.
