Description
Low-shrinkage, fiber-reinforced, one-component structural repair mortar that meets the requirements of class R4 of UNE-EN 1504-3.
Preparation
Mixing proportions: 3,6 - 3,9 liters of water per 25 kg of powder. On concrete surfaces, remove weak, damaged and deteriorated concrete and, where necessary, sound concrete, by suitable mechanical means or high pressure water jet. On reinforcement, prepare the surface using abrasive blasting or high pressure water techniques. Although a primer is not normally required on a surface prepared with adequate roughness, a previous surface wetting is necessary. Do not let the surface dry before applying the repair mortar. When an adhesion bridge is necessary, apply MonoTop-910S or with the same product (MonoTop-412S) make a grout and press on the support. In both cases, the subsequent application of the mortar must be done "fresh on fresh". Where a barrier coating on the reinforcement is required, apply two coats of MonoTop-910S around the perimeter.
Use
Suitable for concrete repair work (Principle 3, method 3.1 and 3.3 of UNE-EN 1504-9). Repair of chipping and concrete damage in buildings, bridges, infrastructures and superstructures. Suitable for structural reinforcement of concrete (Principle 4, method 4.4 of UNE-EN 1504-9). Increase in the bearing capacity of concrete structures through the addition of mortar. Suitable for the preservation or restoration of passivation (Principle 7, method 7.1 and 7.2 of UNE-EN 1504-9). Increase of the covering with additional mortar and replacement of contaminated or carbonated concrete.
Application
Depending on the roughness of the substrate and the thickness of the applied layer, an approximation of 19 kg of powder per cm of thickness and m2 is used (1 bag yields approximately 13,9 liters of mortar). It can be applied by traditional manual methods or by using wet spray equipment. When a bonding bridge is needed, make sure it is still fresh when the repair mortar is applied. When applied manually, press the mortar with a trowel strongly on the substrate. Protect freshly applied mortar from early dewatering with proper curing methods. Concrete must be free of dust, poorly bonded material, surface contaminants, and materials that may reduce bond or prevent suction or wetting of repair materials. In steel reinforcement, remains of rust, mortar, dust, and other materials that may prevent adhesion or contribute to corrosion must be removed.
