| titleOfInvention | Sea sand cleaning effect management method |
| abstract | (57) [Summary] [Purpose] The degree of cleaning of sea sand (concentration of chlorine ions and alkali metal ions) used for concrete aggregates can be easily determined on site. [Structure] To control the cleaning effect of sea sand, the sea sand to be cleaned is loaded into a column of a specified volume, and the cleaning water is continuously introduced into the column from the top to pass through the sea sand. , A large number of liquids after washing that have passed through sea sand are sampled over time, and the chlorine ion concentration and alkali metal ion concentration in the liquid are measured, and both ion concentrations and the sea sand unit that passed through the sea sand at each measurement The correlation with the cumulative amount of cleaning water per unit is obtained in advance, the post-cleaning liquid at the end of cleaning in the actual cleaning process of the sea sand is sampled, and the chlorine ion concentration is measured, By estimating the alkali metal ion concentration of the post-washing liquid from the chlorine ion concentration using the above correlation, and comparing the measured chlorine ion concentration value and the estimated alkali metal ion concentration value with the respective reference values. Determine the degree of sea sand cleaning at the end of cleaning. |
