Abstract
The construction industry has recently seen a considerable shift towards the use of sustainable and green materials due to the rise in pollution and waste which is created by some of the most basic ingredients during its production which releases harmful gases like carbon dioxide leading to the global greenhouse effect and hence results in global warming. Various governmental and international organizations and individuals alike have started working on products that can be used as replacement materials for the ingredients of concrete and mortar such as RHA. Many studies highlighted the inevitability of getting the RHA benefits without using superplasticizers. The present work aims to investigate the optimal dose of superplasticizer with the optimal replacement of RHA that provides the highest concrete compressive strength
