items that binds them together and resists their separation.
Adhesive products can be classified :
•Concrete bonding agents
•Tile grout
•Tile adhesives
44. Concrete bonding agent
Bonding agents are natural, compounded or synthetic materials used to enhance
the joining of individual members of a structure without employing mechanical
fasteners.
The main types of bonding agents used in
the construction industry:
•latex emulsions
• epoxies.
Types Of Emulsions Used As Bonding Agents:
•Styrene Butadiene (SBR)
•Polyvinyl acetate latex (PVA)
