BETEC 302 / BETEC 302 HOZ/ 302 WHITE

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)
Betec 302	0-0.35
Betec 302 HOZ	0-0.35
302 WHITE	0-0.125

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
