It is developed and so formulated can be used to reinstate large sections of concrete or recommended to be used where access is difficult or complex reinforcements do not allow the use of conventional materials or methods. It is based on Portland cement graded fillers and additives which control shrinkage and reduce water demand and facilitate quick and easy working with controlled quality.

APPLICATIONS

This ready to use micro concrete enhances quality of work with its consistent quality which completely eliminates human errors of on site mixing. It can be used to repair large sections of damaged/spalled concrete, making good honeycombs in new concrete. Repairing of structural beams and columns. Repairing defects in Railway sleepers, RCC Hume pipes etc.

METHOD OF APPLICATION

This ready made micro concrete is difficult to mix by hand. Use a mixing vessel. Pour clean water into the vessel at 3.3 litre / per 25 kg bag. Add the micro concrete into it slowly under constant stirring conditions until lump free until a homogenous mix is attained Use a slow speed stirrer only. Where larger quantities are needed a mixer is required Pour immediately to get maximum flow properties. It is not recommended to mix part bag at a time. Once placing of micro concrete is complete and form work removed it is necessary to cure the area by keeping it under wet condition for curing as usual.

PRECAUTIONS

Storage conditions are very important to extend shelf life to 6 months • Do not split pack • For mixing add water exactly as advised • Pour once ready and moist cure as usual.
