Working Mechanism of an Electric Power Trowel
Process of Operation
The operation of an electric power trowel starts with the preliminary smoothness done by a concrete float. After the floating phase, when the concrete is semi-dry, an electric power trowel then comes into play to give the surface a professional and clean finish.
Most electric power trowels operate through rotating blades that are powered by an electric motor. Once switched on, these blades spin at variable speeds which can be adjusted according to the needs of the concrete. The operator holds a control stick, which is used to tilt the machine forward or backward, thereby controlling the direction of the spinning blades.
Around the surface, the operator manoeuvres the machine, ensuring that every section of the concrete slab is covered. When the spinning blades come into contact with the concrete, they create friction which helps smooth out the surface, leaving it with a polished finish.
Despite the machine’s automated process, mastery through careful control is imperative to maintain a consistent floor flatness and floor levelness.
To achieve desired results, professionals often employ multiple passes with the machine, systematically shifting from lower to higher blade speeds as the concrete hardens. Lastly, edging trowels are typically used to produce a crisp finish on edges and corners that the power trowel couldn’t reach.
Remember, the timing of trowel use is essential and varies depending on the moisture content and the type of concrete mix used. Using the power trowel too early can risk damaging the surface, and using it too late may result in an non-smooth surface or may require much greater efforts to finish. The operator must understand the concrete’s behaviour to determine the perfect timing for troweling.
Specific Tasks of Electric Power Trowel in Concrete Work
The electric power trowel primarily serves to compact, smooth and level the concrete surface after it has been initially placed and screeded. In the field of concrete work, it primarily plays a role during the finishing stages of a concrete pour.
One of the initial tasks performed by this tool is known as floating. This process pushes down the aggregate and brings the fine materials, water, and cement paste to the surface, creating a flat, smooth area with a slightly soupy consistency. Floating also assists in compacting the concrete and increasing its density and ultimate strength. It efficiently eradicates any humps, bumps, or depressions present on the concrete surface.
Another important task performed by the electric power trowel is called finishing. After the floating process, finishing is commenced when the water sheen has disappeared, and the surface begins to firm up. The trowel blades are adjusted for a slight pitch, and the machine helps create a smooth, hard surface that’s quite glossy to optimize the concrete’s strength, durability, and resistance to external factors.
Moreover, special techniques called troweling and burnishing can be utilized using the power trowel to achieve specific finishes. Troweling is the process of smoothing the concrete with multiple blade passes to develop a hard, dense surface. Burnishing, performed after troweling, is achieved by increasing the blade pressure on the hard surface, creating a high-gloss finish often seen on polished concrete floors.
Each of these steps, when performed correctly with an electric power trowel, results in a more level, durable, and visually appealing concrete surface that meets both functional and aesthetic needs.
