What is the special work of the concrete mixing station
The ratio of the concrete particles to the surface area, the shape of particles, the density of the particles and the grading of the particles, etc., are very important to the liquidity of the slurry. Smaller than surface area, the particle shape is closer to the ball, bigger, more filling and more liquid. By optimizing these factors, you can obtain the most appropriate liquidity. In order to design the concrete mix according to the engineering requirement, the characteristics of the aggregate material must be mastered first. The properties of aggregates are determined by factors such as microstructure, prior exposure and processing, and these factors influence the properties of fresh and hardened concrete. The effect of aggregate properties on concrete performance should be considered, and the quality of concrete mixing equipment should be considered. Before installation, check the appearance quality of the equipment again, the platform bolts are not loose, the welding seam is not cracked, the oil leak, the water, the ash (the lump), etc. Clean the assembly of the whole machine and re-spray paint, rust and renovate. Prepare the all kinds of bolts, welding wire, iron plate, etc., to prepare tools and protective equipment, the use of more tools for several sets of parts can use pneumatic wrench, and provide timely acetylene cutting, electric welding equipment; Plan the entry time of the crane.

One of the features of the high-performance concrete mixer line is the low water ratio. In order to ensure its liquidity, it must be mixed with an efficient water reducer. Therefore, it is necessary to select cement that is suitable for low water cement ratio. One is the composition of fineness and particles, and the other is the early hydrogenation after the addition of water.
