BETEC 240

Description

BETEC 240 is a so-called non- (wet) shrinking moulding mortar based on Portland cement with microsilica, which has been especially developed for areas which are difficult to reach and for larger surface areas. BETEC 240 is applied in constructions with heavy static and/or dynamic loads and heavy rotating equipment, as windturbines.

Quality control

During manufacturing only high-quality aggregates are used, which meet the strictest requirements. During the production process as well as during the final stages these materials are extensively tested for quality, not only in our own laboratory, but also in independent acknowledged institutes.

Application areas Advantages
  • BETEC 240 is particularly suited for grouting large and heavy constructions which are to be put into operation again within a short period of time.
  • Grouting machines such as compressors, turbines large pumps etc
  • Grouting railway constructions, baseplates and anchors
  • Grouting bearings of bridges, fly-overs etc.
  • Grouting foundations which are heavily loaded like wind turbines
  • Product ready for use, which is easy to process and environment-friendly
  • Chromate reduced
  • Checked volume increase
  • No plastic shrinkage
  • Excellent fluidity characteristics
  • Very high early and final strengths, therefore loading is possible soon after application
  • Resistant to frost and gritting materials, like salt
  • Free of chlorides and other corrosive aggregates
  • Contains no aluminous cement
  • Complies with the requirements drawn up for prestressed concrete
  • Very good adhesion to concrete and steel
  • Highly resistant to oil and grease
  • Can be pumped, vibrated or poured without any danger of de-mixing
  • By adding microsilica a highly dense and homogenous mortar matrix and extremely low permeability are realisedmortar matrix and
Packaging and storage
