چکیده انگلیسی
In the current study, possibility of making structural lightweight aggregate concrete using large amounts of waste material was investigated. The waste materials comprised oil palm shell, which was used as coarse aggregate, and a high volume (50% and 70%) of type F fly ash, as cement replacement by mass. The mechanical properties, such as compressive strength in different curing conditions, splitting tensile and flexural strengths, as well as density, ultrasonic pulse velocity, water absorption, and drying shrinkage up to one year were investigated. All oil palm shell concretes containing high volume fly ash are found to have adequate strength for formwork removal. Oil palm shell concretes containing high volume fly ash had 46%-60% lower cement content compared to previous studies with a similar compressive strength. Although, using high volume fly ash in oil palm shell concrete significantly reduced short-term mechanical properties, however, the use of limestone powder significantly improved the compressive strength at early and later ages. Test results also showed that there is no significant difference between the drying shrinkage of oil palm shell concrete containing 50% fly ash and the control oil palm shell concrete.
