What are the requirements for raw materials for ready-mixed mortar?

Ready-mixed mortar is different from traditional mortar, which requires not only certain strength, but also good water retention, cohesiveness and constructability.

In order to ensure good workability of mortar, water-retaining and thickening materials, such as cellulose ether, thickening powder, plasticizer, etc. , usually added to mortar.

Wet-mixed mortar is transported to the construction site after being mixed by a professional manufacturer, and the transportation volume is large, so it cannot be used up quickly, and it needs to be stored at the construction site for a period of time. Therefore, water-retaining thickening materials and additives with retarding effect become essential components of wet-mixed mortar. These two components can make the wet-mixed mortar maintain operability for a long time before actual use, and should be used up before the mortar hardens. Once used, it can set and harden normally.

There are many raw materials used in ready-mixed mortar, so how to control the quality of raw materials is particularly important.
