On August 15, with the completion of vector testing and commissioning of Puyang East Traction Station of Zhengji high-speed rail, the customer-side equipment was successfully powered, and the last traction station in Henan Province of Zhengji high-speed rail was officially powered.
Zhengzhou-Jinan high-speed rail is 380 kilometers long from Zhengzhou East Station to Jinan West Station, passing through Jinan, Liaocheng, Puyang, Anyang, Xinxiang and Zhengzhou in turn. Among them, the Puyang-Zhengzhou section (Henan section) has been completed and put into operation in June 2022, thus ending the history of no high-speed rail in Puyang, and all 17 provincial municipalities in Henan have opened high-speed rail. The construction of
transportation infrastructure is the foundation and lifeline of national economic development. With the unique advantages of high-speed railway, such as large traffic volume, high timeliness and strong safety, Henan and Shandong will have stronger transportation guarantee, constantly broaden investment and circulation channels, strengthen resource exchange and sharing with surrounding areas, cultivate new economic growth points, and inject inexhaustible impetus into regional economic development.
Railway is the "artery" of the national economy, and high-speed rail is the "booster" of economic development, how to make the "booster" play a greater role? Low-alkali cement plays an important role in it!
Low-alkali cement refers to the cement with low content of alkali metal oxides (potassium oxide and sodium oxide). The total alkali content is calculated by equivalent sodium oxide (Na2O + 0.658K2O ), and the total alkali content (equivalent sodium oxide) of low-alkali cement is required to be less than 0.6%. Compared
with other types of cement, low-alkali cement can reduce the risk of alkali-aggregate reaction caused by active aggregate used in concrete to affect the strength of concrete, reduce the amount of water reducing agent used in concrete, increase the workability of concrete, facilitate construction, improve the durability of concrete, and make the concrete look good after solidification. There are many application scenarios
of low-alkali cement, including railway construction. Because high strength concrete is widely used in concrete sleepers, bridges, catenary poles and other railway products, it is necessary to select high strength cement with matching strength grade. In recent years, railway products have higher and higher requirements for cement performance, and the selection of better and better low-alkali cement brands has become a factor that must be measured in construction.
In domestic cement enterprises, there are many enterprises that can provide high-quality low-alkali cement, including Fangcheng County Wanbei Cement (Group) Co., Ltd., located in Nanyang, Henan Province.
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 rail, Xinyang Minggang Airport, Zhounan Expressway, Xuxin Expressway, Zhengfu high-speed rail 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 use of special low-alkali cement is of great significance for ensuring the construction of high-speed rail. Low-alkali cement can greatly improve the durability, reliability and service life of cement concrete, which also brings a very broad market prospect for low-alkali cement. In the future, we look forward to Wanbei Cement's high-quality low-alkali cement products to help more "high-speed rail dream" blossom!
