Property analysis and development of flexibilizer MZR for new type slag MTC

The toughness of the slag MTC solidified body is poor and can not fulfill the requirement of the exploitation and development of the later stage perforation of oil wells.Therefore,analysis is conducted on the solution to improve the toughness of cement.The flexibilizer MZR for slag MTC is developed based on the combination of fiber,rubber powder,and active particles.Using the criteria of measuring the performance of oil well cement for reference,the properties of MZR are tested through the impact toughness test,the bending strength test,as well as the cementing strength test.What’s more,the effect of MZR on mortar properties is examined.Research results show that MZR can greatly improve the toughness of slag MTC solidified bodies.When 3% MZR is added,the impact toughness,bending strength,and cementing strength of the slag MTC solidified body will be improved by more than 30%.It is proved that MZR is an excellent flexibilizer to the slag MTC technology,which does not have negative effect on impact toughness and does not affect the workability of mortar.
