CX SUPERCONCRETE LS
CX SUPERCONCRETE LS is a dark brown liquid based on lignosulphonates which mixes readily with water and therefore disperses evenly. CX SUPERCONCRETE LS waterproofs by improving the quality of the concrete or mortar. It reduces the water demand for required workability and minimizes segregation and bleeding.
Uses : To minimize permeability and increase the waterproofing properties of concrete and cement sand mortars for critical applications like roof slabs and screeds, basements, external plastering, bathroom floors, water tanks, sumps, drains etc.
Standards compliance:Â Â CX SUPERCONCRETE LS conforms to IS: 2645-2003.
Advantages
Liquid admixture
Instant and complete dispersion throughout the mix. Uniform waterproofing
throughout concrete matrix.
Improved workability
Improves compaction of concrete and mortar, even where harsh sands or
aggregates are used.
High efficiency
Dramatic reduction in permeability of concrete/ mortar
Improved concrete quality
Minimizes porosity and honey combing. Produces dense homogenous
concrete.
Properties
| properties | Values |
| Compatibility | Can be used with all types of cements, including Pozzolanic but not High Alumina Cement. |
| Permeability to water | Less than 15% as compared to 50% max. Allowable under IS: 2645compared to control sample. |
| Setting Time | No significant effect on setting time of concrete or mortar |
| Compressive Strength | Maintains compressive strength equal to control concrete or mortar and can evenimprove on strength property if full advantage of water reduction potential is utilized. |
| Workability | Improves workability at reduced water cement ratio |
Application
Note: Mixes using CX SUPERCONCRETE LS will require much less water than normal mixes for the same workability. Water reduction may be as much as 15% or more. If the moisture content of the sand or aggregate changes i.e., it becomes wetter or dryer, and then the amount of water used must be reduced or increased to give the original workability.
