  Concrete laser leveling machine is the most popular mechanical equipment in concrete floor construction nowadays. Many construction and floor construction units have purchased concrete laser leveling machines, because the labor cost saved by concrete laser leveling machine for construction and the wealth brought by it have been proved by countless users. For users who want to buy concrete laser leveling machine, a question they are more concerned about is how long it will take to recover the cost of the machine. In response to this problem, we summarized the before and after construction comparison of previous customers, and combined with the purchased equipment models and local market to conduct an analysis. Different concrete laser leveling machines have different prices, daily working areas and profits. Taking dz30-2 as an example, the construction area per hour is more than 300 square meters, and the daily workload can be completed in more than 2000 square meters to 2500 square meters. Taking the labor and cost saving of 4 yuan per square meter as an example, the daily profit is about 6000 yuan. If the project goes smoothly, the cost can be recovered in less than two months. Concrete laser leveling machine is suitable for large-area paving work. Through the connection with the power supply, the click generates power to drive the operation of the machine to complete the designated work and tasks. The independent transmitter arrangement of the laser leveling machine can complete large-area building paving, thereby effectively ensuring the consistency of other ground elevations. Moreover, the elevation is not controlled by the template, so the error caused by the machine construction is very small, which can effectively reduce the problem of construction joints and also minimize the subsequent maintenance costs.

  Concrete with large slump: The mixing time needs to be appropriately increased, generally 30-60 seconds longer than concrete with small slump, to ensure that the concrete is mixed evenly, so that the excess water is fully mixed with cement and other materials to avoid segregation. At the same time, the amount of water should be strictly controlled and accurately measured, because the amount of water has a greater impact on the slump. Concrete with small slump: When mixing, pay attention to controlling the mixing force and time to avoid excessive mixing that causes the concrete to be too dry and hard, and lose good workability. Generally, the mixing time is relatively short, so that all materials can be evenly mixed. Concrete with large slump: Prevent concrete from segregation and water evaporation during transportation. The mixer truck should maintain a uniform speed, avoid sudden braking and sharp turns, and reduce the shaking of the concrete in the tank. At the same time, the tank body can be covered with a sunshade to prevent direct sunlight from causing water to evaporate too quickly and affect the slump. Concrete with small slump: During transportation, care should be taken to prevent excessive loss of concrete slump. If the transportation time is long, some plastic preservation measures can be considered, such as adding an appropriate amount of retarder. However, attention should be paid to the amount of retarder added to avoid affecting the setting time and strength of the concrete. Concrete with large slump: The pouring speed should not be too fast and should be controlled within a certain range, such as the pouring volume per minute should not exceed 1-1.5 cubic meters to avoid rapid flow and accumulation of concrete in the formwork, resulting in loose vibration or segregation. At the same time, it is necessary to avoid excessive free fall height of concrete. When it exceeds 2m, auxiliary tools such as string barrels and chutes need to be used. Concrete with small slump: Due to its poor fluidity, some auxiliary measures are needed during pouring to ensure that the concrete can fill every corner of the formwork. For example, artificial auxiliary spreading can be used to evenly distribute the concrete in the formwork to avoid concrete accumulation or local vacancies. Concrete with large slump: It is advisable to use a low-frequency vibrator, and the vibration frequency is generally 2000-3000 times/minute. Avoid using a high-frequency vibrator to cause over-vibration of the concrete. The vibration time should not be too long. The vibration time at each point should be controlled within 20-30 seconds, and the concrete surface no longer sinks significantly, no bubbles appear, and cement slurry appears on the surface. Concrete with small slump: It is usually necessary to use a high-frequency vibrator, and the vibration frequency is generally 3000-5000 times/minute to improve the fluidity and density of the concrete. The vibration time should be appropriately extended, and the vibration time at each point may take 30-40 seconds to ensure that the concrete is vibrated and dense, but it is also necessary to prevent excessive slurry on the concrete surface due to over-vibration. Concrete with large slump: When finishing, wait for the surface moisture to evaporate properly before proceeding, generally 1-2 hours after the concrete pouring is completed. The specific time is determined according to the site environment and the concrete coagulation. Usually 2-3 times of plastering are required to eliminate moisture and defects on the surface. Plastic film, geotextile, etc. should be used to cover the surface immediately during curing to prevent the water from evaporating too quickly and causing the surface to lose water and crack. The curing time is generally not less than 14 days. Concrete with small slump: Plastering can be done in time after the concrete surface is slightly dry, generally about 0.5-1 hour after pouring. Due to its low moisture content and fast surface drying, fewer plastering times may be required, but attention should be paid to the plastering quality to ensure that the surface is flat and smooth. It should also be covered and moisturized in time during curing. The curing time is generally not less than 7 days, but if the environment is dry or the temperature is high, the curing time should be appropriately extended.
