As you know, there are plenty of situations when you mix your own concrete rather than having it delivered from the ready-mix plant. For example, customers often expect to see small sample pours when they are considering decorative work. Whether you are proposing stain, exposed aggregate or stamped concrete, a mixer is a great option for creating samples.
What’s more, in this struggling economy, contractors who used to concentrate on larger jobs are finding that repair and maintenance work can keep a crew busy between big projects – patchwork and resurfacing jobs are perfect situations in which to mix your own concrete.
And the concrete countertop industry is full of artisans who mix their own batches. In fact, mixing your own concrete simply makes sense on many smaller jobs. Most ready-mix companies have a three-yard or more minimum. And what about pours in tight spots (a backyard patio for instance) that require laborers to wheelbarrow the concrete to the site? Because they are easy to move around, mixers are ideal for those situations.
Some choose to mix-on-site for the control it gives them over batch consistency and quality – an increasingly important consideration for decorative concrete contractors. When mixing their own concrete, contractors can control slump, workability, color, and the time of day they pour the concrete.
There are a number of mixers available, both hand-held and machine-type, to do the job. Countertop contractors and companies that specialize in patchwork and resurfacing may find that a hand-operated mixer is best, while contractors that specialize in flatwork may prefer a mixing machine.
Hand-Held Mixers generally consist of a metal shaft with paddles on one end that attaches to a heavy-duty drill. Some manufacturers make shafts specifically for their driver, while others offer shafts that can be attached to a drill of the operator’s choosing. Shafts are usually made of high-strength steel and paddles are available in a plethora of shapes and sizes. There are also “high-shear” mixers designed for GFRC (glass-fiber reinforced concrete).
Mixing Machines are available in a number of sizes (with capacities from about 3 cubic feet to 12 cubic feet) and a couple of basic design shapes (drum or mortar/horizontal shaft). Smaller units are ideal for small jobs and creating sample pours. They are often available with wheels and handles, allowing the operator to wheel the mixer to the job site. Some larger machines include a tow bar.
