LC400R

LC-400R 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. LC-400R is especially beneficial during hot weather concreting operations when control of setting time and maintenance of a placeable consistency are essential.

Advantages

• Provides variable control of setting time based on dosage rate
• Improves quality of concrete by decreasing water-cement ratio
• Increases strengths both compressive and flexural
• Increases density and relative durability
• Resists damage caused by freezing and thawing
• Reduces water content needed for a given workability
• Reduces cracking and shrinkage
• Reduces surface bleeding
• Reduces segregation
• Provides superior finishability on all flatwork and pre-cast surfaces
• Improves pumpability of concrete
• Maintains slump life during extended mixing times
• Aids to reduce peak heat of hydration in mass pour concrete, reducing thermal cracking
• Aids in preventing cold joints
