The proportioning plant inspector is responsible for inspecting control of materials and batching operations.The inspector's duties will start at the time materials are being stockpiled and will continue until final records for the project are complete. The choice of a concrete mix depends on the need of the project both in terms of strength and appearance and in relation to local legislation and building codes.
Concrete producers must “retrain their eyes” for this very fluid mixture as it turns corners and fills forms.
These requirements take into consideration the weather conditions that the concrete will be exposed to in service, and the required design strength.
The compressive strength of a concrete is determined by taking standard molded, standard-cured cylinder samples.
The method of mixing will also be specified, as well as conditions that it may be used in.
This allows a user of the concrete to be confident that the structure will perform properly.Several test procedures have been successfully employed to measure the plastic properties of Self-Consolidating Concrete.
