Water soluble redispersible emulsion powder based on VAC / E can give the mortar the following properties after application of mortar
· Improve constructability.
· Improve the sealing and waterproof performance, and the rubber powder forms a film at the capillary hole wall and microcrack.
· Improve the bonding strength with the interface, the rubber powder forms a film at the interface and improves the intermolecular force.
· Improve cohesion, and the rubber powder forms a film between hydration products, cement mortar capillary wall and micro cracks.
· To improve the flexibility and deformation capacity of mortar, the adhesive film can reduce the elastic modulus, bridge the micro cracks in mortar and the interface between cementitious material and aggregate.
