administration;
procurement department of raw materials;
sales department.
The managers of the latter must undergo special training, get acquainted with the brands of the material, its technical characteristics and areas of application. Wholesale of concrete requires some knowledge and skills in the field of construction.
The classic composition of concrete includes several components:
cement;

dosage of concrete mixture;
Mixing process.
Raw materials components should be cleared of impurities and pollution. Next, it is necessary to knead chemical additives in the mixture, grind cement, heat the aggregates. For dosing of concrete components, special dispensers are used that have a minimum percentage of error. The quality of the material directly depends on the correct norms and dosages of raw material components. Cement and aggregates must be thoroughly mixed to make a high -quality homogeneous mixture. To do this, it is advisable to use concrete mixers working on a gravitational principle.
