Agro-industrial-based wastes as supplementary cementitious or alkali-activated binder material: a comprehensive review

Abstract An attempt to shed light on the use of agro-industrial-based wastes as supplementary cementitious material (SCM) or alkali-activated binder (AAB) is mainly focused in this review paper. The SCM AAB acts a suitable replacement for cement, cement manufacturing tends contribute 8–10% global CO 2 emissions. To gain acceptability construction industry, diverse must demonstrate their potential precursors SCM. materials discussed among agricultural are rice husk ash, olive waste and coconut-based industrial ground granulated blast furnace slag, fly ultra-fine steel slag. paper also analyses effects calcined uncalcined pozzolanic properties system. It clear from studies that tend provide greater reactivity compared wastes, helps early strength development findings indicate hydraulic properties, thereby making them an
