General Information
High performance - are concretes of high strength, low permeability, high corrosion resistance and durability, with compensated shrinkage or expansion, i.e. they possess such qualities the combination or prevalence of which provides a high reliability of structures depending on utilization conditions [46, 47, 64, 75, 82, 89, 90, 91].
The application of such concretes in most cases allows to avoid a «secondary» corrosion protection (protective coatings).

Materials applied

  • MB–01, ÌB-Ñ or Embelit modifiers.
  • Ordinary Portland cement M400 or M500 according to the Russian Standard in the amount not exceeding 500 kg/m3.
  • Hard–rock aggregates.
  • Light-weight gravel with compressive strength of 2…10 ÌPà and bulk weight 500…800 kg/m3.


    • Main concrete properties
  • Compressive strength ranges from 40 to 120 MPa for heavy-weight and fine-grained concrete which corresponds to classes B30…B100.
  • Compressive strength ranges from 40 to 80 MPa for structural light-weight concrete with density grade D1600…D1800 kg/m3, which corresponds to classes B30…B60.
  • Range of short-term and long-term deformation characteristics:
    - for concrete classes up to B60 (compressive strength up to 80 MPa) – according to the existing Russian State Norms and Rules for designing reinforced concrete structures (SNiP 2.03.01-84 and SNiP 2.05.03-84);
    - for concrete classes over B60 (over 80 MPa) – special norms are applied [61].
  • Compressive strength range at normal curing within 24 hours – 25…40 MPa.
  • The level of deformations due to shrinkage is 0.02…0.1% and the value of self-stress - 0.5…3.0 ÌPà.
  • Low permeability to water, gas and chlorides: the water tightness grade exceeds W12…W20;
  • Frost resistance not lower than that of ordinary concretes. With additional use of air entraining or gas forming admixtures can be dramatically increased to grades F700…F1000.
  • Resistance without a protective coating in the following environments:
    - in weak acid environments with pH>3;
    - in gas environments with the concentration of corrosive gas one step higher than the existing Russian norms and rules for corrosion protection in structural design (SNiP 2.03.11–85);
    - in liquid environments with the concentration of chlorides and sulfates one step higher than the existing Russian norms and rules for corrosion protection in structural design (SNiP 2.03.11–85).
  • Increased thixotropy and long-term stability of concrete mixtures, including self compacting which are not subject to segregation.
