Con-Lub SR is mainly composed of 2, 3, 4 Hydroxyl Stearato polycarboxalate, competitive grafts-able emulsified monomers of salts & Ester of Fatty acids & oils, etc.; for very special properties, different ingredients remain in grafted from with the main polymer chain.
Con-Lub SR is white in colour, liquid is paste like mass, depending on temperature. It is partial soluble in water. It is used in Reinforced Cement-Concrete, Cement-Concrete and plastering, etc. in a word, for all kind of concrete. There is no health hazard.
Con-Lub SR is linear polymerizer between cross-linked small lumps in the concrete masses. It also reduces water-cement ratio remarkably, procuring satisfactorily high work-abilities and strength of concrete.

Usages Area
| Con-Lub SR is used to increase workability without loss of strength or to enable water reduction for the sameworkability resulting in dense rheodynamic concrete with highultimate strength. This product is very useful for distance transported pumping concrete, high fluidity concrete, self-leveling concrete, plain concrete, pilling, superstructure, Ready mix concrete, Bridge, culvert, dams concrete etc. in a word in all field of cement using where water pressure is less & thick & rich.
Suitable for concrete in strength class of 30-50 N/mm2 |
Dosage
| The optimum dosage of Con-Lub SR to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. As a guide, the rate of addition is generally in the range of 0.6-1.5% by weight of cement depending on the function. Sets very early with moderate dosage. There may be retarding effect on the setting time with high dosage |
