What is the relationship between the compaction effect of the concrete power trowel and the construction efficiency? 2
1.Good compaction effect helps improve construction efficiency
-Reduce the number of reworks:When the compaction effect of the concrete trowel is good, the ground is flat and dense, which can effectively avoid the need for re-construction due to uneven or loose ground. For example, in the construction of industrial plant floors with high quality requirements, if the initial compaction and troweling can achieve the standard of flatness deviation within 2-3mm, there is no need for a lot of rework to correct ground defects in the future, thus saving time and labor costs. -Speed up the progress of subsequent construction:The compacted concrete surface is flat and solid, providing a good foundation for subsequent construction (such as laying epoxy floor paint, installing flooring, etc.). For example, when carrying out epoxy floor construction, a well-compacted concrete floor can make the coating of epoxy floor paint more uniform, and the drying speed may also be faster, because the dense concrete surface will not absorb too much solvent in the floor paint, thereby shortening the entire construction cycle. -High one-time molding quality:Concrete with good compaction effect has a more expected strength growth and better surface quality. In some projects with tight construction schedules, the ground that can be formed in one go and meet the quality requirements can be directly put into use or proceed to the next process, greatly improving the overall construction efficiency. For example, when building a parking lot, if the ground strength and wear resistance after the trowel compaction meet the design standards from the beginning, the parking lot can be opened in advance, saving time and money.
2.The possible impact of construction efficiency on compaction effect
-Balance between operating speed and compaction quality:If the operating speed of the trowel is excessively increased in pursuit of construction efficiency, the trowel piece will stay in each area for too short a time and cannot fully compact the concrete. For example, in the initial setting stage of concrete, if the trowel passes over the ground quickly, the bubbles inside the concrete may not have time to be discharged, the porosity will increase, and the compaction effect will be affected. Therefore, it is necessary to reasonably improve the construction efficiency while ensuring the compaction effect. -The importance of construction sequence and rhythm:A reasonable construction sequence and rhythm help to ensure both compaction effect and construction efficiency. For example, in the construction of large-area concrete floors, the entire area should be preliminarily compacted first, and then fine compaction and troweling should be carried out. If the construction sequence is chaotic, such as starting fine grinding before completing the initial compaction in some areas, it will lead to uneven ground compaction, which may require rework later, but reduce construction efficiency. At the same time, the rhythm of the construction process is also very important. For example, the start, stop, and turn of the trowel should be smooth and orderly to avoid frequent irregular operations that affect the compaction effect and work efficiency.

Do you know the importance of pre-sales and after-sales services for laser leveling machines?
In the process of purchasing laser leveling equipment, manufacturing quality, market price, technical indicators, manufacturer strength, etc. are all important aspects that can be used to measure the performance of laser leveling equipment. However, in addition to these more important reference factors, the pre-sales and after-sales service of the product should also be fully considered. So, what is the importance of ensuring the pre-sales and after-sales service of the laser leveling machine? See below for a detailed analysis. In modern society, pre-sales and after-sales service is undoubtedly an extremely important link in the development of enterprises. However, there is a saying circulating in the market: "Good equipment does not require after-sales service, no matter how long it is used, it will not break down; and those with good after-sales service are because the equipment is always broken, so they have to rely on after-sales to provide maintenance services continuously." This sentence sounds quite right to laymen at first glance, but it is not the case when you think about it carefully. For products like concrete laser leveling machines, no matter how excellent the equipment itself is, it is inevitable that certain parts will be lost during normal operation. Moreover, how can good after-sales service just stay on "repairing" the machine? After-sales service can be said to be a significant advantage of domestic laser leveling machines. Most of the laser leveling equipment purchased by large concrete floor construction companies is undoubtedly a "big item" in terms of price and equipment size. In addition, the installation, debugging and maintenance of laser leveling equipment require special personnel to operate, which makes the purchase of laser leveling equipment more cautious. However, my country's floor construction companies have many doubts about purchasing laser leveling equipment products in terms of purchase, transportation distance, language communication, and after-sales communication. These doubts are precisely the advantages of domestic laser leveling equipment. Compared with foreign equipment, my country's laser leveling equipment companies are produced and sold domestically, which is convenient for buyers to conduct on-site inspections of products and production workshops. Purchasing domestic equipment is more convenient in terms of purchase procedures, transportation, and later debugging and maintenance. Our service team provides customers with a full set of solutions, from the production, arrival, assembly of the whole equipment, performance debugging, application training, production and maintenance guidance to delivery to customers. The post-service also includes timely repair, maintenance, technical training and other work of laser leveling equipment. This kind of technical support is a good embodiment of after-sales service. Our after-sales service and product quality complement each other and fully reflect the strength of the enterprise. We not only have good quality machines and equipment, but also better after-sales service. In order to facilitate everyone to better understand, the analysis of the importance of pre-sales and after-sales service of laser leveling machines ends here. Our company is a comprehensive enterprise integrating R&D, manufacturing, sales and other technical services of concrete laser leveling machines.

How to strengthen the concrete floor to control cracking
Most of the soil floor is not reinforced, or only nominal reinforcement measures are taken to control the crack width. Reinforcing steel bars placed at the top or top of the floor slab can limit the random crack width due to concrete shrinkage, temperature stress, foundation settlement, external loads, and other problems. This type of reinforcement is commonly referred to as shrinkage and temperature enhancement devices. Shrinkage and temperature enhancement are different from structural reinforcement. Structural reinforcement is usually placed at the bottom of the concrete slab to enhance the load bearing capacity of the floor slab. Most of the soil-bearing structural floors are provided with upper and lower reinforcements at the same time, while controlling the crack width and enhancing the bearing capacity. Due to the construction feasibility and cost of the double-layer reinforcement method, the soil-bearing structure floor is not as common as the non-structure floor. Basic principle If the concrete slab is laid on a high quality base and ensures good support, while using low shrinkage concrete material, the joint spacing is set at 4.5 m or less and installed correctly, there is generally no need for reinforcement. In general, there is almost no cracking at random or non-seam areas. If random cracks do occur, the crack width should also be kept small due to the small joint spacing and the low shrinkage of the concrete material, thus avoiding the problem of subsequent repair or maintenance. When concrete slabs are laid on low-quality bases with more problems, there is a risk of uneven support. When ordinary or high-shrinkage concrete materials or joint spacing exceeds 4.5 m, it is necessary to take reinforcement measures to limit the occurrence of Crack width. When the crack width develops and increases to about 0.9 mm, the load transfer effect of the aggregate locking disappears, causing vertical displacement cracking or "destruction" of the concrete slab. Once this happens, the edges of the crack are exposed, and blasting is likely to occur; and the concrete slab is subject to wheel compaction, especially when high-level forklifts with hard wheels are crushed. Once the blasting phenomenon begins, the crack width of the surface will increase, and the damage of the concrete slab along the crack will deteriorate rapidly. Shrinkage and temperature enhancement methods are required where shrinkage joints are not allowed on site and are not installed. Sometimes, this method is also known as continuous enhancement or seamless flooring, and a large number of closely spaced (90-180 cm) small cracks are allowed on the floor panel. Crack control method Generally, there are two methods for controlling the crack in the soil floor: (1) controlling the location of the crack by installing a shrinkage joint (the crack width cannot be controlled), (2) controlling the crack width by installing a reinforcement device (the crack position cannot be controlled). Using Method 1, we can control the cracking position of the concrete slab; the width of the shrink joint or the crack in the joint is largely controlled by the joint spacing and concrete shrinkage. As the seam spacing and concrete shrinkage increase, the seam width also increases. Similar to the crack, if the seam width is close to about 0.9 mm, the efficiency of locking and transferring the aggregate between the aggregates and avoiding vertical displacement between the seams is greatly reduced. In view of this, many designers use load-conducting designs such as force-transmitting rods, force-transmitting sheets, or continuity-enhancing devices at the shrink seam position to ensure good load transfer and limit vertical displacement between seams. Using Method 2, we allow random cracking of the concrete slab, but with reinforced steel or welded mesh to control the crack width. In general, this method is not used when setting a shrink seam. Cracking occurs randomly, forming numerous numerous intertwined small cracks. Due to the appearance considerations, this type of crack control method needs to communicate with the owner in advance.
