The additive is a generic term for a few materials which could change some properties of mortar, such as redispersible polymer powders (or emulsion), fibers, retarding agents, fluidizing agents, deformation agents for adjusting the volume of mortar, and water-repellent agents. The special performance that additives give dry-mixed mortar is the key to distinguish it from.. read more →

The glass-transition temperature refers to the temperature at which polymers will be converted from an elastic state to a glassy state, expressed by Tg. When the temperature is higher than Tg, the material is rubber-like in behavior and generates the elastic deformation under load; when the temperature is lower than Tg, the material is glass-like.. read more →
