The advantages of low-alkali cement are obvious, which helps the construction of high-speed railway to a new level!

Recently, high-speed rail construction projects across the country have been reported frequently. The first batch of long rails

of Hangzhou-Wenzhou High-speed Railway entered the site safely, the first box girder of Shanghai-Nanjing section of Shanghai-Hefei High-speed Railway was poured, the whole line pull-through test of Guinan High-speed Railway was started, the long rail laying of Jizheng High-speed Railway was completed by 80%, and the first Guiyang-Nanning High-speed Railway with a design speed of 350 kilometers per hour in Guizhou and Guangxi began the whole line pull-through test.. The implementation of high-speed rail construction projects has been steadily promoted, and the efficiency of comprehensive transportation has been continuously improved.

High-speed railway has the unique advantages of large traffic volume, low energy consumption, fast speed, good safety, low pollution and less land occupation. The construction of high-speed railway project is of great significance for facilitating people's travel, improving the comprehensive transportation hub system, promoting the development of rural revitalization, and promoting the economic and social development of the areas along the line. The construction of

high-speed railway is in full swing, which has played a significant role in promoting the demand for low-alkali cement. Why should low-alkali cement be used in the construction of high-speed railway? What are the characteristics of low-alkali cement ? The track foundation and bridge foundation of

high-speed railway are composed of cement concrete. If the alkali metal ions (such as Na +, K +, etc.) In the cement are brought into the concrete, dissolved in the concrete, and then gradually separated out, it will cause the corrosion of steel bars in the concrete and the cracking of the concrete, thus affecting the bearing capacity of the structure. Shorten the service life of the project. Especially when the area where the high-speed railway passes contains a large amount of chemical substances such as sulfate and chloride ions, it will increase the alkalinity of the concrete surface, accelerate the corrosion of steel bars and the aging of concrete, and affect the safety and stability of the high-speed railway operation.

For this reason, it is necessary to use low-alkali cement in the construction of high-speed railway to effectively reduce the content of alkaline elements in concrete, thereby reducing the alkalinity of concrete, improving the corrosion resistance of concrete and prolonging the service life of the project. What are the advantages

of low-alkali cement?

First, the alkali content is low: the total alkali content in low-alkali cement is much lower than that in ordinary cement, which can effectively reduce the corrosion of steel bars in concrete and the cracking of concrete.

Second, the seismic performance is good: the compressive strength and tensile strength of low-alkali cement are relatively high, which can further improve the seismic performance of the structure.

Third, the frost resistance is good: due to the low content of chloride ions in the low-alkali cement, the concrete has a strong frost resistance.

In addition, low-alkali cement also has the characteristics of high early strength, high durability and high permeability, which can ensure the quality and reliability of high-speed railway construction.

Generally speaking, low-alkali cement plays a very important role in the construction of high-speed railway. It can not only ensure the safety and stability of the project, but also prolong the service life of the project, providing a solid guarantee for the rapid development of high-speed rail transportation in China.

In China, Fangcheng County Wanbei Cement (Group) Co., Ltd., located in Nanyang, is undoubtedly one of the outstanding enterprises that can provide high-quality low-alkali cement.

It is understood that Wanbei Cement has excellent mine resources and advanced production technology, and has obvious advantages in the development of low-alkali cement. It is widely used in key national projects such as South-to-North Water Transfer Project, Zhengzhou-Wanzhou High-speed Railway, Xinyang Minggang Airport, Zhounan Expressway, Xuxin Expressway, Zhengzhou-Fuzhou High-speed Railway and Tianchi Pumped Storage Power Station in Henan Province, which ensures and improves the construction quality of these large-scale projects.

At present, Wanbei Cement can not only produce ordinary Portland cement and low-alkali cement, but also successfully develop special cement such as medium and low heat slag Portland cement and oil well cement.

The crisscross high-speed railway lines connect the vast motherland in series, and the brand-new high-speed trains also witness the glorious course of the great rejuvenation of the Chinese nation. In the process of speeding up the construction of a strong transportation country, low-alkali cement is expected to play a greater role in helping the construction of high-speed rail to a new level!
