concrete setting retardant admixture

ATLAS LIGORETARD SC-020

Product description

Concrete setting retardant admixture designed for:
- Production of monolithic concrete (e.g. for application on foundations),
- Production of concrete with extended setting time e.g. in continuous concrete laying,
- Production of ready-mix concrete with significantly extended workability,
- Production of ready-mix concrete in summer conditions,
- Production of concrete for transporting over longer distance.

Main properties

    - Increases workability time of concrete mixture - Delays start of concrete setting - Decreases rate of heat radiation during cement hydration what decreases risk of thermal cracks occurrence - Increases final concrete strength - Does not cause aeration of concrete mixture - Can be used in combination with liquifying admixtures ATLAS DURUFLOW, FORTIS series and plasticizers of ATLAS PRIMO series - Does not cause reinforcement corrosion

Main parameters

    Base: Saccharose water solution Form: Pink liquid Density: 1.06 — 1.10 g/cm3 pH rate: 6.0 — 8.0

DOSAGE

Go top
Recommended:  0.1 — 2.0 % of cement mass
 
Admixture dosage depends on expected delay time, which has to be established as a result of preliminary testing.

SHELF LIFE

Go top
12 months from the production date shown on the packaging. Production date and batch number are placed on the packaging.

STORAGE AND TRANSPORT

Go top
Keep in original, undamaged containers in temperature from +5°C up to +30°C. Protect from freezing and intense sunlight. Mix the product after prolonged storage.

APPLICATION

Go top
ATLAS LIGORETARD SC-020 admixture should be applied in combination with batched water. The mixing time must be sufficient to obtain homogenous concrete mix and it should be determined by preliminary testing. After forming, concrete should be properly maintained in order to reach the designed parameters.
