Super Fine Micro Concrete(SFMC) is a cement based high strength, fast-setting repair mortar for repairing damaged columns, beams and structure. It is self leveled; hence easy to use and economical. It is cement based; hence it has excellent bonding. It requires only on site addition. It is available in 2 grades, 40 & 70. PROPERTIES: SFMC is a high strength precision repair material. It exhibits the following properties: Increased bond strength. Reduces co-efficient of creep. High tensile and flexural strength.
WHERE TO USE: SFMC is ideal for repairing damaged beams and columns. It is suitable for structural repair and can also be used in canals and bridges.
HOW TO USE:
(A) SURFACE PREPARATION: The structure to be repaired should be free from oil, grease, dust, debris or any foreign particles. The surface should be cleaned mechanically using a brush, sand blasting etc. and finally the loose particles must be cleaned by pressure water jetting or with an air blower. Put shutters as required but not
more than 5 feet height at a time.
(B) MIXING: SFMC powder is to be mixed with water in a ratio of 1:0.17. Take the required quantity of water in a
cleaned ghamela or bucket and add the powder gradually under continuous stirring till you get a flowing mortar.
It is better to do mechanical mixing to have uniformity.
(C) APPLICATION: Gradually pour the water-mixed mortar in the shuttered framework. Start water curing after
12 hours of application. Allow it to cure for 24 hours before de-shuttering the framework. After de-shuttering,
clean out the unwetted cured material. SFMC attains strength in 1-3 days and ultimate strength in 28 days.
