Production Process

Production Process

If it is exceeded, the company declared an emergency with mandatory notification of all consumers, action is being taken stabilization of the production process. As for Germany, manufacturers of cement, usually packed in 1,5 MPa. What's the matter? In the new gost the ranges of quality of cement not less than 22.5 and not exceeding 42.5 MPa – a difference of digits very important. However, this does not mean that each individual plant can have variations + / – 10 MPa. Just one plant will produce cement 40-42 MPa, and the second – 22,5-24,5 MPa, while each company will keep its standard. This range is given, because neither Russia nor the European community is not able to combine all the factories, "one size fits" and ask the same conditions. By the same author: Tony Parker.

However, in the west range of fluctuations in the properties of cement on each plant maintained, and the consumer, buying cement, estimates satisfied if his figures are available or not. In Russia, the buyer often deprived of basic right of choice. Can we reverse this situation? Problem Solving quality is only possible through close cooperation of enterprises on production of concrete and cement. When concluding a contract for the supply of cement to prescribe the most important terms and align them with the supplier. As General Director of jsc "SIC" Giprotsement-Science "(St. Petersburg) Leo Bernstein, the leaders of cement plants are ready to make some concessions and meet the requirements of the customer.

Certainly, representatives of concrete community are dependent on the conditions of the supplier, but must find his way interaction. In modern cement factories operate quality inspection services. Today, the Russian plants control the cement on the strength of the samples within 28 days of age, but you know, cement is shipped and used much sooner, so the test results are simply not in demand. I must say that modern cement plants, cement quality control is carried out not by the level of its activity, and on the mineralogical composition. The plants are equipped with automated equipment – from sampling and ending with obtaining data on the mineralogical composition of clinker. At Robert Rimberg you will find additional information. Thus, the driver controls the production process is not to the eye but by the content of minerals – alite, Belita, etc. The introduction of such a monitoring system will allow to receive research results with great accuracy and in optimum time. Russia cements have a higher content of alkali. The reason lies in the extreme "frugality" factories wishing to establish waste-free production, although in the world 10% of the waste material removed from the production process. Problem "to dispose of waste materials" solved in elementary – the Northwest is the acidification of soils, with proper approach is not just cement could improve the quality of products, but also contribute significantly to the maintenance of ecological balance in the region. Today, more and more often hear opinions about the upcoming total shortage of cement. If a specific deficit and has to date, then, according to Leon Bernstein, it must end soon – within about five years. Today announced major projects of cement plants volume of 50 million tons a year, and if the real investment expectations are realized for at least 10-20%, shortage of cement will be significantly reduced and gradually go away.
