The Development of the Strength Index Method and Protocol for Assessing the Use of Solid Waste Materials in Concrete

The reactivity of the sludge ashes, as measured by the SIM showed that the sludge ashes in this study can be classified as reactive using the 28 day index values. Concrete containing sludge ash generally exhibited less compressive strength and modulus of elasticity when compared to concrete containing 100% portland cement (control) at all test ages. The stress-strain relationship for the BP and CR concretes were not as stiff as the control concrete but DU and LM concretes exhibited equivalent stiffness as the control concrete. All concrete specimens exceeded the minimum freeze-thaw requirements for durable concrete as tested under ASTM C 666. Concrete mixes containing sludge ash passed the toxicity leaching test and provide economic benefits to the producer and user.
