Directions for use
PREPARATION
All formwork should be watertight clean and coated with mould oil. To provide a good key for bonding, the base concrete should be free of laitance and soaked with water.
MIXING
Mix cement and aggregates in the mixer or with a shovel. The ingredients are usually added in the following order : 80% of the prepared water, gravel, Ciment Fondu®, sand, balance of the water, to obtain a plastic consistency.
CASTING
For the best performance, the concrete should be compacted by rodding or vibration.
DEMOULDING
Should be done as soon as possible (normally 4-5 hours after casting for non load-bearing structures).
CURING
Due to the rapid evolution of heat during hardening, Ciment Fondu® based concrete and mortars must be kept damp immediately after setting and during the first 24 hours by regular spraying of water, use of wet sacking or a curing compound.
