The setting behavior, mechanical properties and drying shrinkage of ternary blended concrete containing granite quarry dust and processed steel slag aggregate

摘要: Abstract The manufacturing of concrete composites have released high volume carbon dioxide (CO2) gaseous to the environment in world. Therefore, finding an alternative materials replace raw material used production become a current agenda. industrial waste mainly from local coal-fuelled power plant, granite quarrying process, and iron steel industry were utilized high-performance production. incorporated included ground granulated blast-furnace slag (GGBS), pulverized fly ash (PFA), quarry dust (GQD) electric arc furnace (EAFS) partially or completely usage synthetic natural constituent which ordinary Portland cement (OPC), river sand (NRS), rock (NGR). study was aimed establish feasibility using EAFS as partial complete replacement NGR coarse aggregate with other binder fine phase. In addition, method optimization on OPC-GGBS-PFA ternary blended system also established. Meanwhile, optimum combination chemical admixture dosage determined this study. composition established system, NRS-GQD examined various level ranging 0% 100% at increment 20%. properties mixes by setting time test fresh concrete, mechanical strength tests drying shrinkage assessment hardened concrete. results showed that inclusion aforementioned tends improve while, reducing magnitude length change terms shrinkage. With such, compressive 80 MPa able be produced up 80% total volume.
