Dear Sir,
Due to contractor inexperience, we are not able to do the Onsite Concrete Mix with alternate panels as recommended by you in http://www.gharexpert.com/Forum/Concrete-Playground/
Instead, we are planning to use the easier option of RMC for making the Concrete Playground with a smooth finish.
Khoba Work Completed So Far - Contractor has dug and levelled the ground sloping from 6 inches upto 9 inches. He then placed big 10 inch stones and filled all gaps with medium/small/fine stones & coarse sand. He then compacted the whole thing manually with a Giant Hammer
Can you advise how to go about RMC work please.
1. How much RMC will be required for 83 ft x 29ft x 4inch thick ?
2. Which Grade (M10/M15/M20) of RMC to use and its cost per Cubic Metre
3. What precaution to take for RMC laying, vibration and curing ?
4. How to prevent cracks - ( We have seen in Concrete Roads - they do some sort of cutting lines with machine and filling with tar. Is this required ?)
5. What requires to be done after the RMC is fully cured after 10-15 days
Thanks in advance !!
