DESCRIPTION
GK-ZMJ represents a grinding agent used during the process of cement grinding, whose main composition is alcohol amine organic compounds and polycarboxylate polymer. It conforms to National standard GB/T 26748-2011 and European standard EN197, article 5.5. It can significantly improve the early and late strength of fresh cement and improve the output of the mill
USES
GK-ZMJ is widely used during the grinding process of portland cement, composite portland cement, ordinary portland cement, fly ash portland cement, slag portland cement, volcanic ash portland cement, etc.
CHARACTERISTICS
GK-ZMJ offers the following advantages:
* Promotes the hydration of clinker, improves the appearance of hydration products and the strength of cement;
* Leads to strong dispersion of cement powder particles, reduces the agglomeration of fine particles in the process of cement grinding, improves the grinding efficiency of the mill and the sorting efficiency of the powder machine, reduces energy consumption, improves the distribution of cement particle size and the sphericity of cement particles;
* Improves the adaptability of cement and water reducer, cement slurry fluidity and concrete slump;
* Improves fluidity of cement powder, the speed of cement discharge from the warehouses well as the loading and unloading speed of bulk transport vehicles.

APPLICATION | |
RECOMMEND DOSAGE | 0.005%—0.2% by weight of cement. |
USING METHOD | Add GK-ZMJ to the feed belt of the cement mill or to the front bin of the mill through the nozzle. Both needs to be accurately measured. |
NOTES ON APPLICATION | 1. The appropriate dosage is determined by experiment because it related to the factors of mineral compositions of clinker, cement particle distribution, alkali content and sulfur trioxide content of cement and mixing materials type, etc. 2. If freezing or delamination occurs at low temperature, it is necessary to melt and stir slowly before use. |
