Research on the use of fly ash and furnace slag of the Green Star waste power plant to produce high strength concrete in laboratory conditions

Abstract

This article presents the results of experimental research on the possibility of using waste resources from the Green Star waste incineration power plant to produce high-strength concrete in laboratory conditions. The ingredients used include Portland cement mixed with PCB40 But Son, fine aggregate is Lo River yellow sand, large aggregate is crushed stone of size 5 ÷ 10 mm, fly ash and slag at the bottom of the furnace of the power plant. Green Star waste incinerator combined with water-reducing superplasticizer. Research results have shown the possibility of using (20÷30)% of fly ash and slag from the bottom of the furnace of a waste-burning power plant to make high-strength concrete. The resulting concrete mixture has good workability, slump ranges from 15cm to 20cm, compressive strength at 28 days ranges from 50 MPa to 60 MPa. With the current process of developing waste incineration plants to generate electricity, research on the use of ash and slag waste sources from waste incineration power plants is necessary to contribute to promoting a sustainable circular economy. solid.
