BETEC 801 / 804 / 816

Description

BETEC 801, 804 and 816 are so-called non- (wet) shrinking moulding mortars based on Portland cement with high qualitive selected fillers   which are applied in the heavy and medium heavy industries, as well as in road and hydraulic engineering especially where soon high compressive strengths are required, and as well early high temperatures because of f.e asphalt.

* Production on order only.
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
  • Moulding at low temperatures
  • Foundations of steel constructions and machines
  • Grouting of bearings of bridges, fly-overs for example
  • Fastening anchors and reinforcement bars
  • Grouting prefab concrete elements
  • Concrete repair works
  • For mouldings which it is neccessary to get high compressive strengths after very short time as by railway works and production stops.
  • Products ready for use, which are easy to process and environment-friendly
  • Chromate reduced
  • Checked volume increase
  • No plastic shrinkage
  • Very high early and final strengths, therefore loading is possible soon after application
  • Resistant to frost and gritting materials, like salt
  • High fluidity
  • Free of chlorides and other corrosive aggregates
  • Contain no aluminous cement
  • Comply 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 high quality fillers a highly dense and homogenous concrete matrix is realised
Packaging and storage
25 kg bags. Dry and frostproof, storage life 12 months in the original and closed packaging.
