The selection of aggregates has a great importance to achieve a good quality of the final products. The objective of the manufacturer of concrete prefabricated products is to achieve a piece of the mechanical properties required by the international standards with the least amount of cement.
The mixture has to be as homogeneous as possible. We have to make a good dosage of the aggregates, the cement and the suitable water quantity to achieve it.
Use of two sands and colour for the production of wet concrete.
The main characteristics that aggregates should have are as follows: • Hardness • Weight • Finishing • Dimensions
We will obtained these properties if we choose good aggregates, and a good dosage among them, in this case, dosage by weight (aggregates, colour and cement).
