ADDITIVE CONSTRUCTION MIXTURES WITH MICROPARTICLES Russian patent published in 2011 - IPC C04B28/00 C04B24/26 C04B111/20

Abstract RU 2432337 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to additive construction mixtures with microparticles. Use of polymer microparticles of the "nucleus/shell" type in construction mixtures with water hardening, where said particles have a nucleus capable of swelling or swelling under the effect of bases, and the shell consists of polymers with glass transition point lower than 50°C. The invention is developed in subclaims.

EFFECT: high frost- or alternating frost- and thawing resistance.
