EFFECT OF ALKALI SOLUTION DOSAGE ON SUGARCANE BAGASSE ASH BASED SUSTAINABLE ALKALI ACTIVATED SLAG CONCRETESandeep Kumar D.S., Chethan K. and Chethan Kumar B.Abstract Production of ordinary Portland cement (OPC) contributes around 7% of global carbon dioxide (CO2) to environment. In order to reduce the environmental impact caused by OPC production sustainable material development is essential and also sustainable material development plays a vital role in present day construction practice too. Alkali activated slag (AAS) binders is one such sustainable material. Present study investigates the effect of Na2O dosage (4-5.5% of total binder content), modules of silica (Ms: 0.75- 1.75) and bagasse ash (BA) replacement (0, 25, and 50%) to ground granulated blast furnace slag (GGBS) were studied on AAS concrete (AASC) mixture preparation. Mixtures which provide maximum compressive strength were considered as optimal mixture. BA replacement in AASC mixture results in decrease in compressive strength. Further, maximum compressive strength is observed in mixture prepared with alkaline solution of concentration of 5% Na2O dosage, and MS of 1. |
