Can a laser leveler be used to make a ‘three super’ floor?

    Fiber-reinforced concrete (FRC) is notoriously fickle. If you over-vibrate, the fibers-whether steel or synthetic-tend to sink or "nest," leaving you with a non-homogeneous slab and a "hairy" surface that is a nightmare to finish. With a laser leveling, the goal is to keep the fibers suspended in the paste while achieving your ±3mm tolerance. Here is how to dial in your machine: Over-vibration usually happens when the centrifugal force is too high for the concrete's consistency. The Rule of Thumb: For high-fiber mixes, you generally want high frequency but low amplitude. Adjustment: Most laser leveling (like Vanse) allow you to adjust the hydraulic flow to the vibrator motor. If you see "fat" (excessive cream/paste) rising more than 2mm–3mm above the fibers, slow the vibrator RPM down immediately. If the machine moves too slowly while the vibrator is screaming, you are effectively "drilling" the fibers down into the subgrade. The Sweet Spot: Maintain a consistent forward (or pulling) speed. If you have to stop the machine for any reason, shut off the vibrator immediately. Leaving a vibrating leveling head stationary for even 5 seconds will create a permanent "soft spot" or depression in a fiber floor. The vibrator should not be buried in the concrete. Positioning: The vibrator plate should just "kiss" the surface of the concrete as the auger levels it. The Sink Effect: If the vibrator is set too low, it pushes the larger aggregate and fibers down, leaving only weak laitance on top. This leads to surface scaling later in the floor's life. Fibers can sometimes clump (balling) before they even hit the leveling. Auger Interaction: Ensure your auger is set to the correct height (3mm to 5mm above finished grade). The auger's job is to "cut" the excess; if it's too low, it will snag fibers and drag them, creating tears in the surface. Avoid "Double-leveling": With fiber, try to get it right in one pass. Re-vibrating the same area almost guarantees the fibers will settle too deep. Because fibers can make the mix "stiffer," the leveling head might "ride up" on the material. The Fix: Don't increase vibration to force it down. Instead, adjust your Laser Offset. If the machine is riding high, lower the laser receivers by 1MM or 2MM to compensate for the material's resistance without over-working the paste. Variable Adjustment for Fiber Goal Vibrator RPM Reduce by 15-20% Prevent fiber sinking Travel Speed Faster / Consistent Prevent "hot spots" Auger Height Slightly Higher Avoid snagging/tearing Slump Maintain 100mm – 125mm Ensure flow without segregation Pro Tip: Have a "muck man" with a come-along tool standing by to watch the auger. If he sees a "beard" of fibers building up on the plow, you need to stop and clean the head, or it will ruin your FF numbers.   Would you like a guide on how to properly "dry-shake" hardener over a fiber-reinforced floor without creating delamination?

The concrete laser leveling machine can meet the construction requirements of large area, high flatness and levelness. It plays a very important role in the construction process. After the equipment is used, I believe everyone knows about the maintenance of the leveling machine. In this article, our staff will explain to you the three major maintenance misunderstandings of the concrete laser leveling machine. 1. THE BOLTS ARE TOO TIGHT There are many bolts and nuts on the concrete laser leveling machine. In order to make the connection reliable, it should be ensured that it has sufficient pre-tightening force. However, it should not be mistaken to think that the tighter the bolt is, the better. Blindly increasing the torque of the bolt will not only cause permanent deformation of the fastener due to excessive external force, but also cause the thread to slip or the screw to break due to excessive tension. 2. THE TIRE PRESSURE IS TOO HIGH The tire inflation pressure of the concrete laser leveling machine is the main factor that determines its service life and work quality. When the air pressure is too low, the deformation of the carcass increases, which will cause an increase in internal stress, and accelerate rubber aging and cord fatigue; at the same time, the rolling resistance increases, so the tire shoulder wear increases. However, when the inflation pressure is too high, the tire cord will generate a lot of tension, the resistance to impact will be weakened, and the rock edges will easily damage the tire; at the same time, the tire tread will wear more and cause the tire to slip, which will reduce the working efficiency of the concrete laser leveling machine. 3. ONLY DRAIN THE OIL IN THE OIL TANK WHEN CHANGING THE HYDRAULIC OIL The concrete laser leveling machine has many hydraulic components and needs sufficient hydraulic oil. Whenever the hydraulic oil needs to be replaced due to long-term use and deterioration, there will always be people who mistakenly think that it is only necessary to drain the oil in the hydraulic oil and think that it is enough to fill up new hydraulic oil. In fact, the correct oil change procedure should first let go of the hydraulic oil in the hydraulic oil tank, then clean the oil tank and add new hydraulic oil; then remove the circuit main pipe, start the engine and run it at a low speed, and the oil pump truck will be operated manually. If you have maintenance misunderstandings mentioned in the above article when you are maintaining the concrete laser leveling machine, I hope you can correct it in time and adopt the correct maintenance method to avoid machine failure due to improper maintenance. We will continue to organize and publish information about levelings, and you are welcome to pay attention to our website.
