Product Description

Remmers Betofix R-4 is a fibre reinforced PCC dry mortar for the repair of concrete structures with static loads. Combines corrosion protection, bonding layer, coarse and fine mortar in one product. BASt listed. A4 mortar according to RL-SIB and class R4 according to DIN EN 1504-3.

Best Uses

Use Betofix R4 for the repair of concrete elements with rough surfaces in areas with static and dynamic loads. It can also be used for strengthening concrete load-bearing structures since it has a static effect that can be calculated. Repair of road construction elements in accordance with ZTV-ING and repair of hydraulic structures in accordance with ZTV-W.

Application

Requirements for the substrate: Load-bearing, clean and dust-free.

Preparation: Remove the concrete covering from steel parts and derust the exposed steel surfaces to bright metal (SA 2 ½ ). Pre-wet the substrate.

Pour water into a clean container and then add the dry mortar. Mix thoroughly with a mixer for approx. 3 minutes until homogeneous. Maturing time: approx. 1 minute
Mix again for 1 minute until a consistence proper for working has been achieved. If necessary, add some water.

Working conditions:Temperature of material, surroundings and substrate: +5 °C - +30 °C. Low temperatures lengthen, high temperatures reduce working and setting time. Working time (+20 °C) Approx. 60 minutes

After pre-wetting the substrate must still retain some absorption capacity. Apply a scratch coat with the product.On areas that are difficult to access, apply a layer of the slightly diluted product as contact grout. Can be applied in single-layers with a thickness of 5 - 25 mm. In two layers applied wet-on-wet a thickness of < 50 mm is possible. Over broken out areas single layers with a thickness of < 80 mm are possible.

If after the repair the concrete cover is < 10 mm, the reinforcement steel must be protected against corrosion with Betofix KHB. It is not allowed to mixed by hand or to prepare only partial quantities. Initially set mortar cannot be made workable again by adding water or fresh mortar. Protect the mortar surface for at least 4 days from too fast dehydration, frost and rain. The surface should be free of cracks hairline cracks/shrinkage. Cracks are harmless and are not to be faulted since they do not compromise the technical properties of the product.
