Abstract

In order to solve the problems of long time and poor accuracy in the determination of the solid content of accelerant, this paper proposed to use refractometer concentration testing technology to quickly determine the solid content of liquid accelerant. In addition, in order to study the accuracy of the determination method, accelerator samples with standard solid content, different solid contents, and different types were tested by the drying and weighing method and refractometer method, respectively. The results show that: ① for accelerator of the same standard, the discreteness of the test results by refractometer method is smaller, and the data is more stable. There is a better correlation with standard solid content; ② For the liquid accelerator with different solid contents, the correlation between the test results of the refractometer and standard solid content is better than that of the drying and weighing method, which can more accurately reflect the real solid content of liquid accelerator; ③ For the liquid accelerant with different solid contents, the test results of drying and weighing method and refractometer method have good linear correlation; ④ The refractometer method has good adaptability to the determination of solid content of different types/types of the accelerator, and the relative deviation between the modified results and the drying and weighing method is less than 0.8%.
