Cements are divided into three categories according to their uses and properties.
1. General Cement, Cement commonly used in civil engineering. General-purpose cement mainly refers to six categories of cement specified in gb175-1999, gb1344-1999, and gb12958-1999, namely, Portland cement, ordinary portland cement, slag portland cement, pozzolanic portland cement, and powder Coal ash portland cement and composite portland cement.
2, special cement, special purpose cement. Such as: g-grade oil well cement, road Portland cement.
3, characteristics of cement, a relatively prominent performance of the cement. Such as: quick-hardening Portland cement, low-heat slag portland cement, expanded sulphoaluminate cement.
Cement is classified according to its main hydraulic material name
(1) Portland cement, commonly known as Portland cement abroad;
(2) Aluminate cement;
(3) Sulphoaluminate cement;
(4) Ferroaluminate cement;
(5) Fluoroaluminate cement;
(6) Cements based on volcanic ash or potentially hydraulic materials and other active materials.
The main technical characteristics of cement as required in the designation of cement are divided into:
(1) Fastness: divided into two categories: fast and fast;
(2) Heat of hydration: divided into medium heat and low heat;
(3) Sulfate resistance: divided into two categories: resistance to sulphate corrosion and high resistance to sulphate corrosion;
(4) Swelling: Divided into two categories: swelling and self-stress;
(5) High temperature resistance: The high temperature resistance of aluminate cement is classified based on alumina content in cement.

Lathe parts processing refers to the manufacturing process of creating custom metal parts on a lathe machine. Lathe machine is a versatile tool used in various industries including automotive, aerospace, and electronics. Lathe parts processing involves using a lathe machine to cut, shape, and form metal parts according to the required specifications.
The process of lathe parts processing involves several steps. First, the metal material is selected based on the specific requirements of the part to be produced. Once the material is chosen, it is loaded onto the lathe machine, and the cutting process begins. The lathe machine is programmed to move the material towards the cutting tool, which removes material to create the desired shape and dimensions.
Lathe parts processing can produce a wide range of parts in varying shapes and sizes. Lathe machines use a variety of cutting tools, including drills, taps, and reamers, to produce parts according to the required specifications. Additionally, the lathe can produce components with varying levels of complexity, from simple cylindrical shapes to more complex shapes with intricate details.
One of the significant advantages of lathe parts processing is its ability to produce large quantities of parts with high accuracy and consistency. Lathe machines can be programmed to produce the same part repeatedly, ensuring consistency and quality control. This is especially beneficial in industries where a large volume of identical parts is required.
Another advantage of lathe parts processing is its versatility. Lathe machines can be used to produce parts from a variety of materials, including metals, plastics, and composites. Additionally, lathe machines can produce parts with various finishes, such as polished or textured surfaces.
In conclusion, lathe parts processing is an essential manufacturing process in various industries. It offers the ability to produce customized parts with high accuracy and consistency, which is vital in industries where quality and precision are critical. With the ability to produce parts in large quantities, lathe parts processing offers a powerful solution for a wide range of applications.
