Working Mechanism of Redispersible Polymer Powder(RDP)

Dispersible polymer powder is physically mixed with other inorganic binders(such as cement, slaked lime, gypsum, clay, etc) and various aggregates, fillers and other additives such as Hydroxypropyl Methylcellulose(HPMC), polysaccharide(starch ether) and cellulose, finally to produce mortar.

What is the glass-transition temperature (Tg) of redispersible polymer powders?

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;

What is the minimum film-forming temperature (MFT) of redispersible polymer powders?

The minimum film-forming temperature refers to the minimum temperature at which polymers form a continuous film, expressed by MFT. If the cement hydration temperature is below this value, the energy supplied will not be enough to start film formation.

What roles does redispersible polymer powder play in mortar?

The roles that redispersible polymer powder plays in mortar can be considered as follows. First, after water added into mortar, the powder particles will get dispersed in water and quickly form a film under the action of hydrophilic protective colloid and mechanical shear force

What effects does redispersible polymer powder have on the mortar strength?

After redispersible polymer powder is added into cement mortar, the tensile strength and flexural strength of mortar will be significantly improved, while the compressive strength won’t get significantly improved, even declined.
