Performance Based Concrete.
The performance based mix.
Self Compacting Concrete.
Kadaieswari Self-compacting concrete (SCC) is a flowing concrete that does not require vibration and, indeed, should not be vibrated. It uses super-plasticisers and stabilisers to significantly increase the ease and rate of flow. It achieves compaction into every part of the mould or formwork simply by means of its own weight without any segregation of the coarse aggregate. Avoids the voids and honeycombs.
SCC Advantages
-
Health and safety benefits (as no vibration is required).
-
Reduced construction periods
-
Increased workability and ease in flow around heavy reinforcement.
-
Excellent durability.
How to Use
-
The shuttering should be placed properly & designed to support the dead load.
-
Avoid adding water on site.
-
After concrete is poured completely, ensure that concrete surface levels are even. Concrete should not be allowed to dry on the surface and early curing should be done.
-
Concrete curing should be followed as per the guidelines of IS456:2000. (Minimum age of Curing is 14 days)
High Strength Concrete.
Kadaieswari High Strength Concrete (HSC) is a type of concrete with special properties not attributed to normal concrete. High Strength means that the concrete has one or more of the following properties: low shrinkage, low permeability, a high modulus of elasticity, or high strength. The requirements may involve enhancements of placement and compaction without segregation, long-term mechanical properties, early-age strength, toughness & volume stability.
HSC Advantages
-
Reduced dead loads.
-
Improved service life of the structure.
-
High compressive strength.
-
Early pre-stressing at low temperatures.
-
High rise buildings can be built with reduced columns.
How to Use
-
For High Strength Concrete an essential requirement is low water to cement ratio.
-
Avoid adding water on site.
-
Placing the concrete & Curing the concrete should be done properly. Concrete should not be allowed to dry on the surface and early curing must be done.
-
Concrete curing should be followed as per the guidelines of IS456:2000. (Minimum age of Curing is 14 days)
Light Weight Concrete.
Kadaieswari Light Weight Concrete is a mixture that comprises of lightweight coarse aggregate and sometimes a portion or the entire fine aggregates used may be light weight instead of normal aggregates. Structural Light Weight Concrete has an in-place density (unit weight) on the order of 90 to 115lb/ ft³. (i.e., 1440 kg to 1840 kg/m³)
LWC Advantages
-
Reduction in dead loads saves in foundations and reinforcement costs.
-
Improved thermal properties.
-
Improved fire resistance.
-
Savings in transporting and handling precast units on site.
-
Reduced dead load of wet concrete allows longer span to be poured un-propped. This saves both labor and circle time for each floor.
How to Use
-
If the foam additive hasn't been mixed properly, there is a probability of foam collapse, which weakens the product’s compressive strength. Hence, proper handling is required.
-
Concrete attains specified compressive strength in 28-days after casting and curing.
-
Formwork is required to mould it in a shape and to support its self-weight. Shuttering can be of plastic, steel or wood.
