Hydraulic mortar with thixotropic and non-shrinking effect added with synthetic fibers. The product does not contain metal particles and is chloride-free. Teknocaf BF has a strong adhesion to concrete and high resistance to sulphates. Its special composition allows to obtain a thixotropic mortar with high mechanical resistance for both short and long seasoning and excellent durability properties even in aggressive conditions such as marine areas, acid rain, deicing salts, etc … It is in conformity to UNI 8147. Teknocaf BF is used for the structural consolidation of deteriorated reinforced concrete structures such as pillars, beams, ledges, bridges, road and railway viaducts, tunnels, etc … it can also be used to restore deteriorated concrete pavements.
