“UltraTech Plus” is a special concrete with an enhanced Performance with respect to slump retention, early age strength and plastic shrinkage. “UltraTech Plus” is specially designed with careful selection of raw material proportions and special additives to provide this enhanced performance. The Special mix design of “UltraTech Plus” enables achieving excellent workability retentions without any ill-effect on the early strength of concrete. “UltraTech Plus” also provides extended time for placing, compaction and finishing of concrete. There is a considerable change in the hydration process of concrete, which reduces incidence of plastic shrinkage cracking. This in turn improves the structural durability.
There is more time available for placing this concrete, hence it is also suited for complicated structures which typically involves a higher retention time for concrete, eg. columns & retaining walls, etc. “UltraTech Plus” is more cohesive at higher slump values also, hence is suitable for piles, pile caps etc. “UltraTech Plus” is a concrete specially meant for applications like Slabs and other horizontal surfaces due to its better resistance to plastic shrinkage cracks. “UltraTech Plus” is available in all grades above M25.
Advantages of “UltraTech Plus”
- Excellent workability that makes compaction, much easier and more effective
- Extended workability retention hence suitable for columns etc.
- Optimised setting time allows ample time for placing, compaction and finishing
- Offers improved plastic shrinkage crack resistance to concrete
- Superior early strength enables early removal of form work
- Ensures enhanced ultimate strengths and minimum strengths as per specification of IS 456.
- Offers superior surface finish
Recommendations for using “UltraTech Plus”
- Early curing in the form of sprinkling is strongly recommended
- Start of curing before loss of sheen / drying is highly recommended
- “UltraTech Plus” is designed to achieve 80% Characteristic Compressive Strength in 7 days, hence formwork cycle time can be reduced accordingly.
- Sampling and Testing shall be done as per IS specification to get desired results.
Recommended applications for “UltraTech Plus”
- Parking Areas
- Walkways & Platforms
- Industrial floors
- Columns & retaining walls
- Piles & Pile caps
