How to optimize the performance & stability of laser receivers?

  🎈Changes in water-cement ratio: Slump mainly affects pavement strength by affecting the water-cement ratio of concrete. Generally speaking, the larger the slump, the more water is used in concrete. According to the theory of concrete strength, under the condition of certain cement type and dosage, the larger the water-cement ratio, the lower the strength of concrete after hardening. This is because excessive water will form more pores and channels during the hardening process of concrete, and the pores left after the evaporation of water will reduce the density of concrete, thereby reducing the strength of concrete. For example, when the slump increases by 20-30mm from the appropriate value, the water-cement ratio may increase by 0.05-0.1, and the 28-day compressive strength of the pavement may decrease by 10%-20%. 🎈Cement slurry distribution: The appropriate slump can make the cement slurry evenly distributed in the concrete, wrapped on the surface of the aggregate, play a good bonding role, make the internal structure of the concrete dense, and thus ensure the strength of the pavement. If the slump is too small, the concrete is too dry and hard, and the cement paste is difficult to evenly wrap the aggregate, which will lead to more uncemented aggregate particles in the concrete, forming a weak link and reducing the overall strength of the road surface. On the contrary, if the slump is too large, the cement paste will sink due to its own weight, resulting in uneven distribution inside the concrete, resulting in relatively less cement paste in the upper part of the concrete and lower strength, while the lower part may be segregated due to excessive cement paste, which also affects the strength of the road surface. 🎈Aggregate interface bonding: The interfacial bonding strength between aggregate and cement paste in concrete is crucial to the overall strength of concrete. When the slump is appropriate, the cement paste can fully contact and bond well with the aggregate surface. When the slump is not appropriate, such as too large, the cement paste layer around the aggregate will be too thick. During the hardening process of concrete, due to the large shrinkage of the cement paste, micro cracks are easily generated at the interface between the aggregate and the cement paste, weakening the interfacial bonding strength, thereby reducing the strength of the road surface; and if the slump is too small, the cement paste cannot wet the aggregate surface well, which will also lead to poor interfacial bonding and affect the strength of the road surface. In concrete pavement construction, the slump should be strictly controlled, and concrete with appropriate slump should be selected according to construction conditions and design requirements to ensure that the pavement strength meets the design standards.    

As an efficient compact soil surface treatment equipment, the concrete trowel machine has many advantages.
