What are the effects of specific area and sulfur roughness in cement?

The larger the surface area, the finer the cement. Cement that is too fine can easily cause cracks! And absorb external additives! And the strength will also shrink! If the ratio is too small, it will affect the hydration rate and quality of cement. Sulfur directly affects the 28 day strength of cement!


What is the reason for the stoppage of the bucket elevator?

Due to material blockage and poor material transportation in most environments, the bucket elevator experiences overload and then jumps to a stop.

What is the reason for the appearance of white powder and the beginning of slag loss in cement powder walls after a few years?

There are many reasons for this: 1. The wall was originally unsightly and was directly painted without punishment; 2. Process perspective: uneven ratio of cement, gravel, and sand; Poor cement quality (with a low probability); 3. Insufficient viscosity of the wall substrate; 4. Poor putty polishing. The putty application process is not in place; 5. External environmental factors: construction temperature below 10, persistent high humidity, excessive room dust, etc; 6. When applying putty and other processes, the next process is carried out before it is completely dry, resulting in weak bonding of the layer; 7. Not filling small gaps with gypsum powder, etc.
