# How to Make Concrete Mix Ratio: Beauty of Concrete Calculator

Concrete Mix Ratio Calculator: Our daily life in construction industries, tell us many time about What is a Beauty of Concrete Mix Ratio? Because now a days, most of architectural marvelous project come in reality, with the beauty of concrete technology. We are using this formula of concrete mix ratio for many proposes in construction industries. There are many terms like, concrete mix ration for foundations or concrete mix ratio by volume, etc.

## How Much Concrete Mix Ratio Do I Need ???

Today here we see some of interesting facts and figures about concrete mix ratio specifications. As a person of construction industries, i think this beautifully carved out concrete specification texture, in terms of facts and figures, you like it.

### Strong Concrete Mix Ratio for Concrete Grade.

Every Concrete mix have a particular grade. So, what is a Concrete Grade? or What is the meaning of M15 M20 M10 concrete? Here is the simplest term of your question: M10 M15 M20 etc. are all grades of concrete in the Indian Standard issued by Bureau of Indian Standards. The ‘M’ denotes ‘Mix’ followed by a number representing the compression strength of that mix in N/mm^2. A mix is a specific ratio in which cement, fine(sand) and coarse aggregate(gravel) are mixed.

• M5 = 1:4:8
• M10= 1:3:6
• M15= 1:2:4
• M20= 1:1.5:3
• M25= 1:1:2

### Clear Mix Ratio Cover to Main Reinforcement.

Concrete cover for reinforcement is required to protect the rebar against corrosion and to provide resistance against fire. The thickness of cover depends on environmental conditions and type of structural member. The minimum thickness of reinforcement cover is indicated in the drawings, or shall be obtained from the relevant code of practice. Below are the specifications for reinforcement cover for different structural members in different conditions.
