How to Make Basic Concrete Mix

Making basic concrete can be a challenging task. You will need to know how to mix correct ratios of cement, water and aggregate. Mixing concrete requires a bit of labor and the ability to finish your project in a timely manner. 

Supplies needed:

• Portland cement


• Gravel


• Sand


• Shovel


• Water


• Power mixer


• Mixing trough


• Styrofoam cup

1. Take the mixing trough and combine one part Portland cement, two parts sand and four parts gravel. Also be sure to read the manufacturer's instructions for mixing ratios. They can change depending on how much concrete you need. The strength of your concrete depends on correctly mixed ratios. 


2. Mix the compound completely using the shovel.


3. Add water to the mixture slowly. The amount of water greatly affects the outcome of the concrete. Not adding enough water will make the mixture thick and hard to spread. However, too much water will lessen the strength of the concrete. Some manufacturers will have the amount of water that needs to be added on the bag.


4. Mix the concrete thoroughly with a shovel. Depending on the project and the amount of concrete needed, you may need a power mixer to mix compound thoroughly when handling large amounts of concrete.


5. Remove the bottom of the Styrofoam cup and fill it with concrete. If the mixture gradually falls to half the height of the cup, the mixture has a good consistency. You can add more water to get the mixture at the consistencty you need. It should have a cake batter-like consistency.


6. Use the concrete in a timely matter. Concrete can begin to dry in as little as 15 minutes.
