The quality of cement pipes is the guarantee of engineering quality. The factors that affect the quality of cement pipes are cement pipe equipment, processing steps and the selection of raw materials for cement pipes. Let's talk about the selection of materials for cement pipe production
1. In general, we should choose mechanical crushed stone. Such stones have a rough appearance, and the concrete produced is easy to stick together, and it can effectively prevent the concrete from falling. Another choice of pebbles may be broken stones, which can reduce friction between each other.
2. There is less cement mixed with dry and hard concrete, and the amount of unilateral cement is low. Generally, there will be no shrinkage cracks. It has greater benefits for the stability and compactness of concrete, avoiding the inner wall subsidence, and improving steam curing. Ordinary Portland Cement.
3. Regarding the selection of sand, do not choose too fine or too rough, generally use medium sand.
The selection of raw materials is a key step affecting the quality of cement pipes, so it cannot be ignored.
