Set Retarders & Hydration Control

Riteks HydraStop™ is a hydration stabilizer that helps maintain slump and proper set times of freshly produced concrete over extended haul times and increased ambient temperatures. Hydra-Stop can offset issues caused by extended haul times, excess drum revolutions or the effects of temperature and time.

HydraStop helps in the summer months when hydration is accelerated due to higher ambient and mix temperatures. HydraStop helps control concrete temperature when a maximum mix temperature is specified. Concrete performance properties are maintained while exceeding the requirements of ASTM, AASHTO and CRD specifications.

Riteks SYAD™ 75 is a retarding admixture we recommend for all concrete where you desire extended setting characteristics, particularly in hot weather. SYAD 75 delays time of set to accommodate long haul times, or facilitate placement and finishing during hot weather concreting.

Features and Benefits

• Delays setting characteristics
• Improves workability and finishability
• Excellent retarding properties

FormTard 50 is a retarder for vertically exposed aggregate surfaces in concrete forms with nominal depth etch up to 1/4″. FormTard 50 is a
nonflammable, 100% V.O.C. free, paintable gel designed for easy application to vertical concrete forms.

Riteks SYAD™40 is a set retarding water reducing multi-component admixture for concrete. It is designed to facilitate the placing and finishing of concrete while providing control over the set time. SYAD 40 improves pumpability of concrete and is especially beneficial during hot weather concreting operations when control of setting time and maintenance of placeable consistency are essential. SYAD 40 provides superior finishability on all flatwork and pre-cast surfaces.

Features and Benefits

• Variable control of setting time
• Improves concrete quality by decreasing water:cement ratio
• Maintains slump life during extended mixing times
• Increases compressive and flexural strengths
• Reduces cracking, shrinkage, surface bleeding, and segregation
• Resists damage caused by freezing and thawing (aids in preventing cold joints and reduces thermal cracks)

SYAD 30 improves pumpability of concrete and is especially beneficial during hot weather concreting operations when control of setting time and maintenance of placeable consistency are essential. SYAD 30 provides superior finishability on all flatwork and pre-cast surfaces.

Features and Benefits

• Variable control of setting time
