Daye Peak Held Low-alkali Cement Production Seminar
News In order to ensure the quality of low-alkali cement to meet the requirements of key project contract indicators, to increase the market share of "Peak " brand cement high-end products, 5# December, Daye Peak Cement Company organized a special seminar, special discussions on low-alkali cement ingredients, production, quality management and other matters.
low-alkali cement refers to cement with low content of alkali metal oxides (potassium oxide and sodium oxide) (total alkali content is calculated as equivalent sodium oxide (Na2O + 0.658K2O ), and low-alkali cement requires total alkali content lower than 0.6% ). In engineering construction, the alkaline substance in the concrete raw materials chemically reacts with the active ingredients to generate swelling substances or water-absorbing swelling substances, which in turn causes the concrete to produce internal self-expansion stress and crack, which is called "alkali aggregate reaction " (abbreviated as AAR) . Because the alkali aggregate reaction generally occurs gradually after several years after the concrete is formed, the durability of the concrete is reduced as a result, and in severe cases, the concrete will lose its use value. Moreover, because the reaction occurs in the whole concrete, the damage caused is difficult to prevent, prevent, repair and rescue, and is called "concrete cancer " . Therefore, many projects, especially railways, bridges and other large-scale projects require the use of low-alkali cement. Since its production, Daye Peak has participated in the construction of key projects in many countries, provinces and cities, and has accumulated a lot of experience in the production of low-alkali cement.
The production of low-alkali cement requires the use of low-alkali clinker, low-alkali gypsum and low-alkali mineral admixtures. Low alkali clinker must be produced with low alkali limestone and other low alkali raw materials. At the seminar, Daye peak management team and quality control department, manufacturing department, mining and other relevant personnel attended. Combined with the limestone resources and early production experience of Daye Peak Mine, a detailed and comprehensive discussion was carried out. The Quality Control Department puts forward a plan for the batching scheme and process control of low-alkali cement, and formulates detailed alkali control measures from the work links such as the quality control of mine limestone, the substitution of low-grade sandstone for clay batching, and the adjustment of mixed material varieties. The mining department, manufacturing department and other relevant departments put forward their views and suggestions on the problems that may be faced in the actual production process.
Daye Peak requires all relevant departments to attach great importance to and cooperate closely, optimize the production organization in strict accordance with the predetermined quality control index requirements, and minimize the adverse factors affecting the operation quality of the kiln, so as to ensure the high quality and high yield of the kiln, ensure the stable production of low alkali cement, and provide customers with high-quality products.
