Definitions

  • the structure of a cement-bound concrete is traversed by capillary pores (radius: 2 ⁇ m - 2 mm) or gel pores (radius: 2 - 50 nm). Pore water contained therein differs in its state form depending on the pore diameter.
  • These hydrophobic salts reduce the surface tension of the water and accumulate at the interface between cement grain, air and water. They stabilize the microbubbles and are therefore found in the hardening concrete on the surfaces of these air pores again.
  • the notation (meth) acrylate as used herein means both methacrylate, e.g. Methyl methacrylate, ethyl methacrylate, etc., as well as acrylate, e.g. Methyl acrylate, ethyl acrylate, etc., as well as mixtures of both.
  • the shell (B) consists predominantly of nonionic, ethylenically unsaturated monomers.
  • Preferred such monomers are styrene, butadiene, vinyltoluene, ethylene, vinyl acetate, vinyl chloride, vinylidene chloride, acrylonitrile, acrylamide, methacrylamide, C1-C12-alkyl esters of (meth) acrylic acid or mixtures thereof.
  • Tg (P) denotes the glass transition temperature of the copolymer to be calculated in degrees Kelvin.
  • Tg (A), Tg (B), Tg (C), etc. designate the respective glass transition temperatures (in degrees Kelvin) of the high molecular weight homopolymers of monomers A, B, C, etc. measured by dynamic heat flow differential calorimetry (Dynamic Scanning Calorimetry, DSC).
  • the polymer content of the microparticles used can be from 2 to 98% by weight (weight of polymer based on the total weight of the water-filled particle).
