latex modified portland cement mortar

Oct 01 1984 · To obtain a high bond between the latex concrete overlay or mortar patch and the base concrete a bond coat is brushed or broomed onto the prepared concrete surface This bond coat can be the mixture used for the overlay or patch or may be made by mixing undiluted latex with portland cement

Polymer modified mortar is produced by mixing water with polymeric admixtures Portland cement and sand The addition of polymer improves mortar’s performance and consequently can be utilized advantageously and economically in several applications Latex polymers redispersible dry polymers watersoluble polymers are the different types of polymer used to produce polymer modified mortar

Latex Modified Portland Cement Mortar or Concrete This repair material is used to prevent chloride attack on concrete structure due to the use of low watercement ratio This is the same as ordinary Portland cement mortar or grout with the addition of a latex emulsion The strength of this material is same as ordinary mortar or grout

Dec 03 2010 · The first thing to understand is that polymers are primarily used to modify mortars portland cement water sand aggregate not concrete mortar larger aggregates such as gravel or stone due to the relative cost involved The main exceptions are polymermodified concrete for bridge deck overlays and road repair work
