Hydraulically bound mixtures

Hydraulically bound mixtures consist of aggregates, sand, water and binder. These mixtures (including sand cement, draining lean concrete, and stabilised foundation) are produced by a mixing plant.

Foundations for road construction, airports and other areas intended for traffic.

• Inspection of the raw materials, both environmental-hygienic (legislation) and technical aspects.
• The performance of each mixture must be determined on the basis of a preliminary study, under the supervision of COPRO.

• Indication of BENOR and the 8-digit code of the technical datasheet on the delivery note.
• The technical datasheet is available at extranet.copro.eu.

• For contractors, governments, but also for the private sector, trust in the quality of hydraulically bound mixtures is of fundamental importance.
• Certification of hydraulically bound mixtures certainly adds value to their various applications.
• The hydraulically bound mixtures are checked at regular intervals by the producer, under the supervision of COPRO.
• The instructions for use (including the workability period) of the mixtures is an important element for obtaining high-quality foundations.
• Supervision of the production process, the dosing quantities and the final product. This keeps the properties of the hydraulically bound mixtures constant.

Regardless of how well the mixture is produced and its quality, it remains essential to ensure that parameters relating to the laying of hydraulically bound mixtures are respected on site. Respecting the workability period as well as correct and sufficient compaction contribute to a long life for the installed product.
