Natural pozzolan (NP) comprises siliceous and aluminous materials that react chemically with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious properties. Commonly derived from volcanic ash (VA), clay, and certain shales, natural pozzolans are valued in the construction industry for their ability to enhance the durability and strength of concrete while reducing its environmental impact. Utilizing natural pozzolan in concrete mixtures is particularly advantageous under severe environmental conditions where enhanced resistance to chemical attacks and sustainability are crucial.
