Admixtures are added during the mixing of concrete, accounting for less than 5% of the cement mass, and can significantly improve the performance of concrete. The characteristics of concrete admixtures are that there are many varieties and small amounts, which have a great impact on the performance of concrete, so a metering structure is required.
