Minimum RCC beam size should not be less than 9″x 9″ (225MM X 225MM), with an additional slab thickness of 125 MM. I generally use a minimum of 4 bars, with 2 bars of 12 MM thickness in the bottom of the beam, and 2 bars of 10 MM at the top of the beam. I maintain a concrete cover of 40 MM. I recommend use of M20 grade of concrete (1 part ...

Cement: 2% to 3.5%: Due to the fineness of cement, it may fly away by air when cement mixes with the other ingredients. Sand: 8% to 12%: The sand is sieved for plastering work and other finishing works. So some coarser sand will be neglected while sieving and some particles are dropped off during transportation. Coarse Aggregates: 5% to 8%

Ratio of Steel required to Cement Concrete In civil engineering the thumb rule for Steel to Concrete ratio is 100:130. The ratio means for every 130 kg concrete 100 kg of steel is needed. 100 kg of steel strengthen the structure in RCC. Failing this ratio of steel to concrete would cause weakening the structure and fatal cracks to it.
