About us we must not be rusty for cement drainage pipes, and they should be used in our homes. Let ’s take a look at the main application places and uses of the cement drainage pipe with the editor of Wanxin.

As an important city construction material, as for the guarantee of people's daily life, it is very important to include groundwater and underground pipelines. In general, in order to make the exterior beautiful and neat, the cement drainage pipes are buried underground. In modern underground operations, the cement pipes are not only used in urban sewer projects, but also widely used in the power industry. This information is used in the supply of strong electricity. Together, because of its special characteristics, it is particularly applicable to the transportation of water resources, which enables smooth and pollution-free transportation of water resources.

We know that the important point in the manufacturing process of cement pipes is the use of concrete data, together with the use of steel bars as their primary framework, and the use of cement concrete as the primary covering part, so it is called reinforced concrete. This kind of raw material will make it possible to ensure its role in the process of use, greatly improve the power used, can maintain safety and durability in the wet operating environment on the ground, and will not be corroded by soil and some corrosive items. Some special materials were added to the manufacturing process together, making them have good flame retardancy, and will not cause damage or large-scale hazards due to fire. Pipes related to other materials, such as metal pipes and plastic pipes Have better service life. The cement does not have magnetic properties, so some problems in the power transmission process will not occur in the power transmission, and the stability in the power transmission is improved. Therefore, the cement pipe can be said to be an important building material!

The usefulness of the original data of the cement drainage pipe: water is required for satisfactory cement hydration. The water-cement ratio commonly used for concrete is 0.40 ~ 0.65. The water that exceeds the hydration needs is mainly to satisfy the needs of workability. Excessive water leaves holes in the concrete, which adversely affects the strength, density, and various durability of the concrete, such as cement pipes. Water leakage occurs due to the increase of water. Seriously affect quality.

The influence of cement on the function of concrete mainly lies in the type and quantity of minerals and the fineness of cement. Tricalcium silicate in cement is the primary mineral of cement clinker, with a content of about 50%, and is the primary source of cement gelability. The reaction of tricalcium silicate with water is called hydration, and hydrated calcium silicate occurs in a gel-like form. The hydrated calcium silicate gel acts as a cement for sand aggregates in concrete, fills the pores therebetween, and hardens into artificial stone.

Gravel is called aggregate, also known as aggregate, which accounts for about 70% to 80% of the volume in concrete. For a long time in the past, the aggregate was regarded as an inert material, and it was considered that it only played a role in forming the volume in the concrete, and had little effect on the function of the concrete.
