When using cement pole making machines in Shandong, there are specific requirements for the raw materials used, such as cement, water, sand, and gravel, which must be properly metered and mixed. The concrete strength grade of cement poles should be classified according to the type of cement pole: the concrete grade of prestressed concrete poles should not be lower than C50; the concrete strength grade of reinforced concrete poles should not be lower than C40.

Material requirements: Concrete mixing should strictly follow the required proportions. The proportions of cement, water, and admixtures should not exceed 1% to 2%; the proportion of sand and gravel should not exceed 1% to 3%. High-precision electronic weighing equipment should be used for mixing. The moisture content of sand and gravel should also be measured according to climate changes to adjust the mixing ratio accordingly.
