MAXI RETARD is a powerful set retarder for materials made of hydraulic cement, usable in the field of mortars, concretes and grouts.
By delaying the setting of the cement,
MAXI RETARD minimises the amount of instantaneous heat released in the material during the hardening phase. Thus, the risk of cracking due to thermal shrinkage is reduced.
By reducing the mixing water by 10%, its plasticising effect allows the same workability to be maintained and increases strength.
ADVANTAGES :
• Compliant with standard NF EN 934-2.
• Delays the setting of concrete and mortar.
• Avoids restarts of concrete pouring.
• Does not reduce or alter the properties (mechanical strength) of concrete.
• Does not increase the air content of mortar or concrete.
• Eliminates the need for watering in hot weather.
• Significantly reduces crazing, slight differences in hue and cracking.
