Process Flow of Cement Prefabricated Houses

The process flow of cement prefabricated houses mainly includes five steps: raw material proportioning and mixing, mold making and pouring, reinforcement treatment, drying and curing, and surface treatment.

Raw material proportioning and mixing: This is the fundamental step in the production of cement prefabricated houses. Raw materials such as cement and sand need to be precisely proportioned according to the design requirements of the house components. Different components, such as walls and floor slabs, have varying requirements for the strength, durability, and other properties of the raw materials, so the proportioning will differ accordingly. The proportioned raw materials are poured into a mixer, where the rotation and mixing action of the mixer ensure that all the raw materials are thoroughly mixed to form a cement slurry with a certain degree of fluidity and plasticity, preparing it for subsequent pouring work.

Mold making and pouring: Appropriate molds are made according to the shape and size of the house components. The quality of the molds directly affects the appearance and dimensional accuracy of the components. The well-mixed cement slurry is slowly poured into the molds. During the pouring process, attention should be paid to controlling the speed and height to avoid the formation of air bubbles and segregation. At the same time, the molds should be filled to the edges to ensure that the cement slurry fully fills every corner of the molds, guaranteeing the integrity of the components.

Reinforcement treatment: When pouring some important structural components, such as foundation pit columns, to enhance the strength and stability of the components, reinforcement materials such as rods are inserted into the cement slurry. These rods can function similarly to steel bars, improving the tensile and compressive strength of the components, making the columns more robust and capable of bearing greater loads.

Drying and curing: After the cement slurry is poured, it requires a period of drying and curing to reach the designed strength. During this process, the ambient temperature and humidity should be well-controlled to prevent the cement components from cracking due to excessive moisture evaporation. Generally, the curing time varies depending on factors such as the type of cement and environmental conditions, usually taking from several days to several weeks.

Surface treatment: When the cement components reach a certain strength, their surfaces need to be treated. Tools such as scrapers are used to level the poured cement surfaces, removing any protrusions and uneven parts, ensuring that the cement fills every corner and making the component surfaces smoother and flatter, thereby improving the appearance quality of the components.
