Answer / ronak shah

if you calculate the quantity of cement in this ratio, it
is more than 450kg/m3( it is around 873kg/m3). as per IS
456, there is no effect of cement above 450 kg . there is
so many problem above 450kg/m3, due to heigh quantity of
cement heat of hydration effect is more. crecks problem
