How to Make Concrete from Scratch
Master the art of mixing concrete with the perfect ratio for construction projects.
Materials & Tools Needed
Step-by-Step Instructions
Gather Materials
Assemble all materials in your work area. The basic ratio is 1 part cement, 2 parts sand, 3 parts gravel, and about 0.5 parts water by volume.
💡 Pro Tip
Always use clean, potable water for best concrete strength.
Prepare Mixing Area
Set up a wheelbarrow, mixing trough, or concrete mixer in a well-ventilated area. Wear safety glasses, gloves, and a dust mask during mixing.
Measure Dry Ingredients
Using a bucket as your measuring tool, add 1 bucket of Portland cement, 2 buckets of sand, and 3 buckets of gravel to your mixing container.
Mix Dry Components
Thoroughly mix all dry ingredients together using a shovel or hoe until the color is uniform throughout. This ensures even concrete strength.
Create a Crater
Form a crater or depression in the center of the dry mix. This will hold the water and make mixing easier and more controlled.
Add Water Gradually
Pour water slowly into the crater while continuously mixing from the outside in. Add water in small increments to avoid making the mix too wet.
💡 Pro Tip
Proper concrete should be thick but pourable, like thick oatmeal consistency.
Mix Thoroughly
Continue mixing for at least 3-5 minutes, ensuring all dry material is incorporated. The concrete should be uniform in color and consistency throughout.
Test and Use
Test consistency by making a small pile. It should hold shape but slowly flatten. Use immediately as concrete begins setting within 90 minutes.
