apefast CF/L is a liquid admixture made from high-efficient, chloride-free hardening accelerators developed in MAPEI research laboratories.

Mapefast CF/L is a solution of inorganic salts dissolved in water with the capability to accelerate the hydration process of cement, thereby reducing the setting time and increasing the strength of the mix after short curing cycles. The accelerating effect of Mapefast CF/L is generally greater when the temperature of concrete or the surrounding temperature is lower than +10°C during the pouring phase.

Mapefast CF/L is an admixture made from chloride-free, non-corrosive set accelerators and is used to make reinforced concrete without potentially corrosive effects. Mapefast CF/L is a catalyser for the formation of hydration products, reduces setting times and accelerates the development of mechanical strength, especially at low temperatures.

Mapefast CF/L is an admixture that may be used with any type of concrete in both precast plants and mixing plants. With precast concrete, Mapefast CF/L accelerates the development of concrete’s mechanical strength after short curing cycles, thus reducing the time to strip formwork and making the production cycle more efficient. In the ready-mix concrete sector, Mapefast CF/L allows concrete to be poured at a lower temperature, reduces setting times and allows finishing operations to be carried out earlier. Mapefast CF/L may be used to great effect in all those applications that require the following:
• high mechanical strength after short curing cycles;
• shorter steam curing cycles;
• pouring of concrete when the surrounding
temperature is lower than +10°C;
• optimisation of production cycles;
• reduction of form stripping times;
• mixing of reinforced concrete;
• the use of flying formwork.

The amount of Mapefast CF/L varies and depends on specific site requirements, characteristics of the materials, surrounding temperature during pouring and rate of acceleration required. Preliminary laboratory tests are recommended in all cases to identify the amount of product required to reach mix design specifications. Mapefast CF/L may be added to the mixing water without affecting its accelerating properties, but it must never be mixed with other admixtures. To get the best results, we recommend adding Mapefast CF/L to concrete that has already been admixed with a superplasticiser and to mix until it has completely blended with the other components (cement, aggregates and water).
