Comparison between the Compressive Strength of Binary and Ternary Alkaline-activated Pozzolanic Concrete

This research compared the compressive strength of binary and ternary alkaline-activated pozzolanic concrete. Rice husk ash (RHA) Metakaolin (MK) combined partially with Ordinary Portland Cement (OPC) each are concrete while combination rice metakaolin (RHA/MK) OPC is The was replaced at 15% RHA, MK RHA/MK in ratios 0.33 (X), 0.5 (Y) 1.0 (Z) sodium silicate (NS) to hydroxide (NH) as activator. A mix design ratio 1:2:4 water-cement 0.65 alkaline liquid pozzolan 0.30 used process study. Physical properties constituent materials well chemical analysis pozzolans were determined. Slump compacting factor tests done on freshly mixed determine their workability compression test performed hardened cube samples side 150mm obtain strength. Curing for 7 28 days inside water tank. result showed that continuously increased increased. At maturity age 28days, values 14.2 MPa, 17.5 MPa 20.3 0.33, respectively. These higher than RHA taken separately same NS NH which 28days curing 10.9 14.8 16.2 14.0 15.3 18.2 MK. can be construction industry normal work serve effective waste disposal agricultural products such reduce environmental pollution.
