Method of Application Surface Preparation Surface laitance and unsound concrete must be chipped away and smooth surface should be made reasonably roughed to provide proper bonding between old concrete to new micro concrete, after cleaning, saturate the concrete surfaces with clean water. Ensure that the formwork has suitable drainage outlet for excess water so that no free-standing water is present on surfaces before applying of CAC®-POWERCEM MC 40. Mixing Use mechanical mortar mixers, preferably of the slow speed (300-400 rpm) paddle mixer or revolving drum type mixer. Hand mixing rarely achieves the desired result. Allow approx. 5 minutes for mixing. Thorough mixing is essential for achieving maximum results. Add CAC®-POWERCEM MC 40 slowly into recommended amount of clean water in a mixer. Use as little water as is required for ease of placement. CAC®-POWERCEM MC 40 Single Component General Purpose Pre-mixed Flowable Micro Concrete

Version: CS/V1/0124 For Flowable Mix :3.50 – 4.25kg of water to 25 kg of CAC®-POWERCEM MC 40 (W/P Ratio: 0.14 to 0.17) For Plastic Mix: 3.00 – 3.75kg of water to 25 kg of CAC®- POWERCEM MC 40 (W/P Ratio: 0.12 to 0.15) Job placing conditions, including temperatures may require mixing water adjustments as may be essential for practical purposes. Small trial batches to ascertain the best working consistency for the operation are recommended. Application Pre-wet the existing concrete surface to an SSD condition prior to application of micro concrete. In order to prevent air voids, apply mixed CAC®-POWERCEM MC 40 from one side or corner only. CAC®- POWERCEM MC 40 should be placed within half an hour of mixing. During that time keep material in mixer well agitated. After half an hour discard any mix that shows signs of stiffening. Flowable mix may be used with low pressure cement grouting equipment or may be hand rodded into restrained sections. High points must be adequately vented to allow entrapped air to escape. Plastic mortar may be rodded into place or trowel handled where freedom of movement permits. Consistency can range from thick cream to smooth plastic. For large volume of placement areas CAC®- POWERCEM MC 40 may be pumped with a heavy-duty diaphragm pump, screw or any other standard pump. CAC®-POWERCEM MC 40 shall be used in the thickness range of 20mm to 100mm in single pour. For thickness of a section is more than 100 mm, 40-50 % (by weight of CAC®-POWERCEM MC 40) 6-10mm down washed coarse graded aggregate shall be used to reduce temperature built up which may cause crack in the hardened micro concrete. For large flat floor area, 50% aggregate can also be used if the thickness is 50- 75mm with glass/aluminium strip in 1.5 -2 m box grid to avoid irregular crack development. Curing Curing is essential part of CAC®-POWERCEM MC 40 system. After completion of concreting work, the open edges shall be cured by applying suitable CAC®- POWER KURE WB or any other effective curing membrane manufactured by CAC. Other curing methods, such as covering with plastic sheet, wet hessian cloth is also accepted.
