It's the proportion of the water mass to the amount of cement that is added to concrete. This ratio directly influences how strong the mix of concrete. The common w/c ratio for various grades of concrete ranges from 0.40 and 0.60.

Concrete is made up of two components. The main element that determines the quality in concrete are cement, and water.
In concrete the ratio of the amount of water compared to the cement's weight is known as the ratio water-to-cement (w/c). Water and cement are the two primary elements responsible for gluing everything together.
The ratio between cement and water is the most important factor in the durability and strength of the concrete once it is properly cured.
For instance, if the Ratio W/C is 0.40 this means for each 100 lbs of cement used to make the concrete an additional 40 pounds of water is added.

What Happens? If You Add Too Much WaterIncorporating too much water into concrete may cause cracks, shrinkage, and a decrease in overall strength. A lot of water makes concrete more difficult to handle which can cause bleeding and segregation issues in concrete.
If there isn't enough water the concrete will turn rigid and difficult to fill and hard to compact. It could cause honeycombing to form in concrete. It increases the effort in moving concrete.
When the right ratio of water to cement is achieved, concrete will become more durable, and porosity and the color will be well-balanced.
The recommended ratio of water cement for concrete
For normal concrete work (sidewalks as well as driveways): 0.6 to 0.7
If a higher-quality concrete is preferred: 0.4
The ideal ratio for water-cement is between 0.40 to more than 0.60.
An amount of 0.3 makes concrete too rigid (unless superplasticizers are employed).
An amount of 0.8 makes concrete very wet and quite thin concrete.
The normal compressive strengths of concrete when it is properly dried are:
0.4 w/c ratio -> 5600 psi
0.8 w/c ratio -> 2000 psi.

Concrete is a macrocontent.It has micro components like cement, fine aggregate, sand and Coarse aggregate. To obtain high-strength concrete that can withstand the required compressive force, we require the right proportion of admixture that can combine these components.
Then comes the Water that will start the chemical reaction by adding between 23% and 25 percent from the concrete volume. This triggers the chemical process that creates 15% of the water cement paste, which is also called a gel. It is used to fill in the gaps in the concrete.
In the above paragraph, we require 23% water to start the chemical process on cement.
If you add more water than the allowable limit for water cement could impact the force.
If we keep adding water to increase the working capacity the concrete will have lots of fluid materials in which the aggregates will begin to settle. When the water has evaporated it will leave a lot of gaps in the concrete that affect the strength of the concrete.
If we do not follow the rules to preserve the strength of concrete, it could impact the concrete's workability and make it hard to work with and move them.
The ratio of water to cement is determined by dividing the amount of water content in 1 cubic yard mix ( in pounds) by the cement contained in the mixture (in the pounds). Thus, if one cubic yard of mix contains 235 pounds of water and 470 lbs of cement, the mix has an .50 ratio of water to cement.
If the mix is listed as having water in gallons, then multiply the number of gallons by 8.33 to figure out the amount of pounds inside the drink.
