Ultratech cement gets very trusty brand in India till now. I have use about 1000 bags on mite site last month. its get more trusty because of its quality of cement and customer seervice support. if we use with proper instruction follows cement gives maximum streangth.
They are giving customer support while your slab get casted by cubes testing under 7 21 28 days. optimum quality when use to slab I find its leakproof and specified steangth which is requires for structure. price is littile bit high any other cement but good quality gets which is we go for long term investment in structures.
