CX Superplast 550
CX SUPERPLAST 550 Mortar Plasticizer is supplied as off-white to pale yellow liquid which mixes readily with water in any proportions. It is based on internationally recognized chemicals and is free from calcium chloride and similar salts.
Uses :To improve workability and toweling properties of sand/cement mortar mixes during application to increase quality of masonry and plastering
Advantages
Improved moisture retention and bond strength
Slows down drying out of mortar which remains
workable longer. Ensures better bond to all surfaces, including ceiling.
High workability
Even with harsh sands, makes creamy easy-to-apply mortar.
Better & safer masonry
Mortar fills joints easily and efficiently and ensures stronger construction.
Increased productivity
Speeds up work by easy application of mortar.
Makes mortar crack resistant
Minimizes drying shrinkage cracks and increases frost resistance in
cold climates.
Cost saving
Increase yield of the same quantity of sand/cement. Extra coverage normally exceeds material costs.
Improved appearance
Mortar cuts cleanly from faces of brick, block or stone work.
Properties
| properties | Values |
| Chloride content | Nil |
| Compatibility with cements | Can be used with any type of Portland, Super Sulphate, Blast furnace or Pozzolanic cements. |
| Setting time | There is no significant effect on the setting of sand/cement mortars. |
| Plasticizing action | CX SUPERPLAST 550 Mortar Plasticizer entrains a controlled amount of microscopic air bubbles which increase cohesion and provide lubrication to the sane particles in the mix, thereby imparting improved workability to the mortar. The air bubbles hold the cement/water matrix at the contact surfaces which results in improved bond strengths. |
| Frost resistance | Where this is a consideration, that air entrainment appreciably increases the frost resistance of the fully cured mortar and also improves that of fresh mortar, as established by international practice. |
| Increased yield | The special action of CX SUPERPLAST 550 Mortar Plasticizer causes the cement particles to disperse evenly throughout the mix, which combined with its air entrainment property, expands the volume of the mortar. Increase in yield for the same quantities of sand and cement is typically between 8% and 18%, depending upon the coarseness or fineness of the sand used. |
| With typical mixes of 1:3 and 1:4 cement | sand, the cost of CX SUPERPLAST 550 Mortar Plasticizer will normally be recovered and, in most cases, a net cost saving will be obtained, as a result of the increased yield. |
Application
Note:Do not add CX SUPERPLAST 550 Mortar Plasticizer directly to dry sand/cement mortar.
1. Add between 0.100 and 0.2 liters of CX SUPERPLAST 550 Mortar Plasticizer to every 100 liters of water
and stir well to ensure even dispersion.
2. Use the CX SUPERPLAST 550 Mortar Plasticizer / water mixture to make the mortar in the usual way and keep adding and mixing until the required workability is obtained.
