What is the difference between a stabilized soil mixing plant and a concrete mixing plant?

Although stabilized soil mixing plants and concrete mixing plants are both building material mixing equipment, they have significant differences in processing materials, production products and application scenarios. Only by clarifying the differences can accurate selection be made. 

The processing materials and proportions are significantly different. The stabilized soil mixing plant uses soil, sand, lime, cement, etc. as raw materials, and mixes them through precise proportions. The amount of cement in the raw materials is relatively small, usually accounting for 3%-5%. The concrete mixing plant uses cement, sand, gravel, water and admixtures as core raw materials. Cement as a cementitious material accounts for a high proportion, and the water-cement ratio needs to be strictly controlled to ensure the strength of the concrete. 

The performance and form of the products produced are different. The stabilized soil produced by the stabilized soil mixing plant is a semi-rigid material with certain compressive strength and stability. It is mostly in a loose or plastic state and needs to be spread and rolled on site. The concrete produced by the concrete mixing plant is a plastic or dry hard slurry with its own cementitiousness. It can solidify and form itself after pouring, and its strength is much higher than that of stabilized soil. 

Each application scenario has its own emphasis. stabilized soil mixing plants are mainly used for road base and cushion construction, such as roadbed treatment for highways and municipal roads, and are also suitable for basic projects such as airport runways and square foundations. concrete mixing plants are widely used in building main structures, bridges, tunnels, water conservancy projects, etc., responsible for the material supply of load-bearing components such as beams, slabs, and columns, and need to meet the requirements of different strength grades (C15-C80). 

The equipment structure and process are different. The equipment of the stabilized soil mixing plant is relatively simple, and most of them use continuous mixing, with high production efficiency but slightly lower precision. The concrete mixing plant is equipped with a forced mixer, which requires accurate measurement of each raw material. The production process is intermittent, and the control system is more complex, which can monitor key indicators such as slump in real time. 

After understanding these differences, you can choose equipment according to project needs: choose a stabilized soil mixing plant for base construction, and a concrete mixing plant for main structure construction. Reasonable selection can improve construction efficiency and material quality.
