Plastic expanding agent for settlement resistance of high flow state cement based cementing material and preparation method thereof
The invention provides a plastic expanding agent for settlement resistance of high flow state cement based cementing materials and a preparation method thereof. The raw materials include, by weight, 30-50 portions of an azo compound, 10-30 portions of a stabilizing agent, 5-20 portions of a catalyst and 20-40 portions of a rheological additive. The plastic expanding agent provided by the invention can be compounded with efficient water reducer and other additives, and can assist auxiliary additive to realize the flow properties of cement based cementing material, effectively improve the workability, wrapping performance and durability of the cement based materials, has certain compensating shrinkage effect on early age shrinkage of cement based cementing material, and shows anti-settlement and anti-segregation effects while maintaining the high flow state of cement based cementing material.
