摘要
The grouting materials commonly used for drilling in complex formation should have good time controllability and consolidation body strength.Based on the above,a composite grouting material was developed with the orthogonal experimental method.Cement,initiator and promoting agents were added in unsaturated polyester in order to make grout solidify within the limited time.The final formula curing time is 62 minutes and compressive strength is 32.6 MPa.As chemical slurry,it has the characteristics of good-grouting,low viscosity,high intensity,and good plastic performance with the advantage for the lower cost by adding cement to the slurry.
