Pozzolan-based eco-adsorbents were synthesized by geopolymerization with addition of hydrogen peroxide (H2O2) mass ratios 0% (GP0) and 1% (GP1) the products used to sorb cationic methylene blue (MB) dye from water. The chemical composition, textural properties, mineral surface functional groups, as well morphology internal structure these samples determined X-ray fluorescence, adsorption nitrog...

The development of sustainable, environmentally friendly alkali-activated binder has emerged as an alternative to ordinary Portland cement. engineering and durability properties using various precursor combinations have been investigated; however, no study focused on the impact high-volume natural pozzolan (NP) acid resistance NP limestone powder. Therefore, current assesses (volcanic ash) powd...
