At present, a considerable part of admixtures are supplied by foreign manufacturers, and the reference dosage of products is also provided by suppliers.
As a result, the cost of dry mixing mortar products remains high and it is difficult to popularize the common masonry and plastering mortar with large volume and wide area.
