cross section area of 10mm=78.5
cross section area of 12mm=113.04
get the Ratio=113.04/78.5=1.44
new spacing is 1.44*175=252mm
to get cross section area of rebar use pi*(D/2)2
For one-way slabs, the maximum spacing of reinforcement is the lesser of three times the slab thickness (3h) or 18 inches (450 mm). The minimum reinforcement area for shrinkage and temperature, often used for this purpose, is specified by the American Concrete Institute (ACI) code.
