Abstract Hazardous and waste residue resulted from pyrolyzed oil cuttings were solidified with a waste-slag solidifier CS. Laboratory studies have been conducted on the effect of the amount of CS on the unconfined compressive strength, water stability, frost resistance
and the characteristics of the leached pollutants of the solidified cutting
of the prolyzed oil cuttings with solidifier
higher compressive strength and coefficient of thawing for 15 times, the solidified prolyzed oi
cutting
s. Using XRD, SEM and MIP, the solidification mechanisms
s been discovered that prolyzed oil cuttings solidified with CS had
of the reference samples. After alternate freezing and ad higher compressive strength, lower mass losses and
good integrity. Leached liquids from the prolyzed oil cuttings treated with solidifiers containing 6%-15% CS conforms to the class I
requirement of the standard GB 8978
1996. After the solidification treatment, there were large amount of C—S—H gels and small
amount of Aft in the solidified cuttings, making them much denser. The solidified cuttings have higher compressive strength, better water stability and frost resistance, and the leaching of pollutants from the prolyzed oil cuttings is also inhibited.
Key words Prolyzed oil cuttings; Solidify; Water stability; Altemate freezing and thawing; Solidification mechanisms
