As a mechanical equipment for industrial and civil construction projects such as roads, bridges, water conservancy, and docks, concrete mixing plants are one of our indispensable products now. However, in recent years, especially for engineering concrete mixing plants, in addition to improper operation methods, one of the most important factors affecting the working performance of concrete mixing plants is the material mortar. Today we will take a look at the specific factors.
1. The number of cement slurries is large and the activity is large. Too much, slurry flows; too little, collapse.
2. The consistency of cement slurry
The consistency of cement slurry is determined by the water-cement ratio. The water-cement ratio is small, the cement slurry is thick, the activity is small, and the cohesion and water retention are good. Too small, it cannot be constructed densely; too large, it reduces strength and durability.
3. The sand ratio of cement slurry is certain. If the sand ratio is too large, it is dry and thick, and the activity is small; if it is too small, the cement slurry will flow and segregate.
4. Cement variety and aggregate properties
The cement is fine and has good activity. Pebble concrete is more active than crushed stone concrete.
5. Temperature, time, and admixtures.
