BETEC 302 / 302 HOZ

Description

BETEC 302 and BETEC 302 HOZ are non- (wet) shrinking synthetic modified (PCC) repair mortars with synthetic fibres based on Portland cement or blast furnace cement, applied for cosmetic repairs.Material can also be suplied on special request as 302 WHITE.

Type Grain structure (mm)  
302 0-0.35  
302 HOZ 0-0.35  
302 WHITE 0-0.35  
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
  • As an overlay of 2-20 mm thick
  • Reprofiling damaged concrete
  • Filling hollow spaces
  • Filling air pores
  • Product ready for use, which is easy to process and environment-friendly
  • Chromate reduced
  • Checked volume increase
  • No plastic shrinkage
  • 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
Packaging and storage
20 kg bags and 12 kg plastic buckets for the 302 WHITE. Dry and frostproof, storage life 12 months in the original and closed packaging.
