High Range Water Reducing and Retarding Admixture
MNC－HHJ

Description
MNC-HHJ is a high range water reducing and retarding admixture which extends concrete setting time. It meets requirements with ASTM C 494 for Type G water reducing, high range and retarding admixtures.

Application
1. MNC-HHJ retards the initial and final set of concrete. It extends the initial setting time of portland cement concrete by 2 to 3 hours at 21 ℃. MNC-HHJ is used wherever a delayed setting is needed to insure sufficient delivery, placement, vibration or compaction.

Features & Benefits
1.  Pale dark powder. It's non-toxic and nonflammable.
2. High water reducing rate and remarkable retarding effect.
3. Improved early strength after final set.
4. Increased concrete workability and comprehensive properties.
5. 15-20% of cement saved without sacrificing concrete strength and slump retention.
6. Improved concrete impermeability and anti-freeze/thaw ability.

Uses and Dosages
1.It can be added during mix or after mix, while the latter approach is preferential.
2.MNC-HHJ dosage normally ranges from 0.4% to 1.0% by weight of cementitious material, while recommended dosage is 0.5%.
