Mixing Concrete – Machine Mixing

QUIKRETE concrete mixes can be successfully mixed by hand or machine mixed.  For larger projects, machine mixing is often the best method.

Project Instructions

When working with cement-based products, always wear eye protection and waterproof gloves. Machine mixed concrete should be mixed in a barrel-type mixer.

Step 1
Measure the recommended water amount for the number of bags to be added to the mixer and pour half of the water into the mixer (each 80-pound bag will require about 3 quarts of water). If using liquid cement color, add to the mixing water.

NOTE:  water should be added to the mixer before the dry mix.

Step 2
Turn the mixer on and add the dry mix into the mixer.  Allow the concrete to mix for about a minute and then add the remaining water as necessary.

Step 3
Mix the concrete for about 3-5 minutes, until a uniform, workable consistency is achieved. If additional water is needed, add small amounts of water sparingly. Properly mixed concrete should look like thick oatmeal and should hold its shape when it is squeezed in a gloved hand.

NOTE: the more water that is added to the mix the weaker it becomes; adding one extra quart of water per 80 lb bag can reduce the strength of the concrete by up to 40%.

Step 4
Keep the mixer running and dump the concrete into a wheelbarrow for transporting to your work area.
