Method for rapidly detecting content of mixed materials in production course of cement

Abstract

The invention relates to a method for rapidly detecting the content of mixed materials in the production course of cement, which comprises the following steps of: forming a simultaneous equation set by detecting acid consumption value, ignition loss and sulfur trioxide of the cement and the components thereof and solving the content of each component in the cement through the excel matrix functions of a computer according to the characteristics of difficult acid dissolution of coal ash, high ignition loss of limestone and high content of sulfur trioxide in gypsum. The invention finally develops a set of detecting method for rapidly and accurately detecting the content of the mixed materials in the cement through a large number of experiments and production practices, and the content of the mixed materials in the cement can be detected in 30 minutes by adopting the method, thereby meeting the control requirements for the production quality of the cement. The method can realize the timely and accurate control of the content of the mixed materials in the production course of the cement and enhances the use level of the mixed materials in the production of the cement, thereby enhancing the quality of the cement and reducing the production cost.

Description

technical field [0001] The invention relates to the field of cement detection methods, and is suitable for rapid determination of the amount of admixture in the cement production process. Background technique [0002] The addition of admixtures in cement production can not only improve the performance of cement and reduce the cost of cement production, but also make full use of various industrial wastes and reduce the environmental pollution caused by these industrial wastes. Proper admixtures mixed into cement can give full play to their activity and help to improve the performance of cement, but excessive mixing will significantly reduce the performance of cement. Since the chemical composition of the admixture in cement is similar to that of cement clinker, it is very difficult to detect the amount of admixture in cement products. In order to ensure the qualified performance of cement in actual production, the control index of admixture is often set very low, making Admi...

Problems solved by technology

[0004] GB / T12960-2007 "Quantitative Measurement of Cement Components" test method, although the test results using this method are accurate, but different test procedures must be used when testing different types of cement, especially when testing composite cement with many types of mixed materials. The procedure is too cumbersome, which is not conducive to the mastery of the inspectors; the detection time of this method is long, and it takes about 6-8 hours to determine the amount of cement mixture. Such a long detection time is meaningless for the quality control of cement production.
