In order to ensure the stability of the slurry quality, in addition to improving the quality of sand, cement, admixtures and admixtures, the key is to have a suitable mix ratio, including the composition, dosage and mix of raw materials.
Sand adjustment: Nowadays, resources are in short supply, and suitable sand sources are basically unable to be supplied stably. The mix ratio can only be optimized through sand.
The purpose of sand preparation is to meet the grading requirements of the mortar and avoid faults, which may lead to poor workability of the mortar. Mix ratio focuses on coal ash and quality control.
Coal quality is unstable and a batch is the same, so the dosage is determined through sampling testing.
If the ammonia smell is strong and the color turns black, the dosage must be controlled. Production is not recommended to avoid workability of the mortar.
The mixing ratio of the additive dosage is adjusted according to the raw materials and determined through experiments.
If the dosage adjustment range is large, quality problems with other raw materials must be found from the proportions to avoid later quality accidents.
