How to Mix QUIKRETE® Concrete: Machine Mixing
Concrete mixing using electric mixer
Machine Mixing Concrete. QUIKRETE concrete mixes can be successfully mixed by hand or machine mixed. For larger projects, machine mixing is often the best method. When working with cement-based mixes, always wear rubber gloves and safety glasses. During concrete mixing and placing procedures, machine mixed concrete should be mixed in a barrel mixer mixing. Blades in a barrel mixer are attached to the inside of the rotating
barrel machine mixing the concrete. Measure the recommended water amount for the number of bags to be added to the mixer and pour half the water into the mixer, before adding any of the concrete mix. Each 80-pound bag will require about three quarts of water. Typical mixers can hold up to three bags of 80 pound concrete mix. Add the dry mix into the mixer. Then, allow
the concrete to mix with the water, for about a minute. Add the remaining water, as necessary. The concrete should be mixed for about three to five minutes until a uniform, workable consistency is achieved. If additional water is needed, small amounts of water may be added, sparingly. When mixing concrete, it is important to know that the more water that is added to the mix, the weaker it becomes.
Adding one extra quart of water per bag can reduce the strength of the concrete by up to forty percent. Properly mixed concrete should look like thick oatmeal and should hold its shape when it is squeezed in a gloved hand. Keep the mixer running and dump the concrete into a wheelbarrow for...
