Characterization of Alkali Activated Bentonite - Fly Ash as Brick Material

Abstract Brick, one of the most common binding materials which need excess energy during manufacture. Gathering of excess industrial waste creates the environmental pollution as well as a health issue. To developing green environment, industrial waste can be used as an alternation of binder material as a brick. In this present study combination of sodium bentonite and fly ash get activated by sodium hydroxide (NaOH) and calcium oxide (CaO) whose Na 2 O/CaO proportion varied as 1 with mole content. Mixing proportion of both solid particles were varied as 40/60 and 60/40 as weight percentages. Casted samples were conducted for the curing period of 0 days, 3 days, 7 days, and 28 days. Mineralogy, morphology, and compressive strength tests are conducted and found that 1.5 moles are the best for developing compressive strength that obtained as 135.8 kPa at 60°C oven curing temperature.
