TamCem 66
Overview
TamCem 66 is a new-generation superplasticiser for concrete. It contains state-of-the-art polycarboxylate ether polymers and is specially formulated to give exceptionally high water reduction, enhance workability and offer superior slump retention for up to 4 hours. It is a non-chloride liquid admixture which has been formulated to comply with the requirements of EN 934-2 (Table 3.1 and 3.2) and ASTM C 494 for Type F high-range water-reducing/ superplasticising admixtures. TamCem 66 is compatible with all types of cement meeting recognised international standards.
TamCem 66 is based on versatile polycarboxylate co-polymer technology. Its unique long-chain molecular structure enhances the dispersion of cement particles, by means of steric hindrance, whereas conventional BNS and SMF-based superplasticisers, will only undergo less powerful electrostatic repulsion. It is because of this that TamCem 66 requires a lower dosage compared to conventional superplasticisers but still provides extreme workability characteristics for high slump, flowable, self-compacting concrete with a greatly reduced water demand.
Superior finishes with reduced honeycombing
Key specification
- High water reduction and offer superior slump retention up to 4 hours
Key benefits
- High water reduction that enhances high early and ultimate strengths, low permeability and high durability of the concrete
- High flowability provides for easy placement and compaction
- Excellent cohesion, zero segregation, minimal bleed water and extremely high levels of workability
- Enhanced slump retention and easier placement and delivery control especially under warm climatic conditions
- High elastic modulus, low shrinkage and creep are achievable using graded coarse and fine aggregates
- Superior finishes with reduced honeycombing
Typical applications
- High performance concrete
- Improving mixing efficiency during large pour
- Highly flowable concrete
- Highly durable concrete
- Ready-mixed concrete
- Self-compacting concrete
- Pumped concrete and wet sprayed concrete
- Long distance transportation
- Helping to reduce environmental impact
