NexCrete ES
JUMP TO
GENERAL DESCRIPTION
Riteks NexCrete™ ES is a normal setting multi-range water-reducing admixture for concrete utilizing next generation polycarboxylate technology. It is designed to facilitate the placing and finishing of ready mixed concrete that is highly flowable and workable for extended periods of time with normal setting characteristics. By varying the dosage rate, NexCrete™ ES can be used as a normal, mid-range and high-range water-reducing admixture.
APPLICATIONS & BENEFITS
FEATURES & ADVANTAGES
APPLICATIONS & BENEFITS- Improves the quality of concrete by decreasing water-cementitious ratio
- Increases high early and ultimate strengths, both compressive and flexural
- High durability and increased density
- Reduces damage caused by freezing and thawing
- Reduces water content needed for a given workability (12-40%)
- Reduces surface bleeding, cracking, creep, and shrinkage
- Reduces segregation and increases cohesiveness
- Improves finishability, workability, and pumpability of concrete
- Maintains slump life during extended mixing times
- Plasticity range of 8 to 11 inches
- Improves bond strength to the steel
- Reduces permeability and salt penetration
Recommendations
APPLICATIONS & BENEFITS
NexCrete ES should be added with the initial mixing water or incorporated with the final water at the end of the batch sequence. It is not unusual to experience significantly lower air entrainment dosage requirements (50-75%) when compared to conventional high-range water reducers.| Dosage to meet ASTM C 494 Type F applications: 7 to 20 fl. oz. per 100 lbs.| Dosage to meet: ASTM C 494 Type A applications: up to 3 fl. oz. per 100 lbs.| Dosage to meet mid-range applications: 3 to 6 fl. oz. per 100 lbs. Due to variations in concrete materials, job site conditions and applications, dosages outside of the recommended range may be required. In such cases, contact your local Riteks Construction Chemical Representative. Note: NexCrete ES does not contain calcium chloride or any chloride-based components. It will not promote or contribute to corrosion of reinforcing steel in concrete.
