Recent developments in recycling techniques have transformed non-renewable resources into partially renewable resources. In this regard, the function of supplementary cementitious materials (SCMs) in concrete is critical in order to minimize extra waste going to landfills. In the manufacture of eco-friendly concrete, there are several products and wastes of considerable importance. These products may be categorized as industrial, agricultural, and aquaculture wastes, natural minerals, dust, powders, and ashes. In regard to the application of such wastes, literature has emphasized the massive potential of utilization of volcanic pumice powder ash (VPPA) in the production of green concrete as a partial substitution or as admixtures to cement. The major goal of utilizing SCMs is to lessen carbon dioxide emissions, as carbon dioxide is positively related to climate change and other forms of environmental pollutions. Furthermore, the re-use of byproducts and wastes helps in mitigating problems associated with the disposal of waste materials. This article aims to provide a comprehensive review of existing literature on the utilization of VPPA in concrete and its impact on concrete characteristics, such as workability, compressive strength, flexural strength, splitting tensile strength, and durability performance. Also, this article aims to examine the influence of VPPA on sustainability by analyzing the microstructure of concrete utilizing a scanning electron microscope (SEM). The findings concluded that the utilization of VPPA with partial substitution lessens workability and compressive strength, while improved perfromance in the flexural and split tensile strength in addition to durability characteristics is reported. This article also highlights future research advancements needed in this domain.
