Ready-mixed mortar is different from traditional mortar. In addition to requiring a certain strength, it is more important to have good retention, adhesion, and constructability. In order to ensure good workability of the mortar, water-retaining thickening materials, such as cellulose ether, thickening powder, plasticizers, etc., are usually added to the mortar.
Because the wet mortar is mixed by a professional manufacturer and transported to the construction site, and the volume of transportation is large, it cannot be used up quickly and needs to be stored at the construction site for a period of time. Therefore, water retention is very important. Thickening materials and retardant admixtures have become essential components of wet mortar. These two components allow the wet mix mortar to remain operable for a long time before actual use, and should be used before the mortar hardens, and can set and harden normally once used.
There are many raw materials used in ready-mixed mortar. In addition, the development of ready-mixed mortar in my country has just started. How to control the raw materials is particularly important. The raw materials not only determine the working performance and usability of the ready-mixed mortar, but more importantly, the durability performance is closely related to the service life of the building.
