Move your mouse over image or click to enlarge
Mapegrout Thixotropic is a shrinkage compensated, fibre-reinforced thixotropic mortar for repairing concrete, the repair of corners, beams, columns and balconies damaged by rusted reinforcing rods. Due to its high mechanical strength can be used for structural repairs.

Key Features
  • Repairs up to 35mm in one application
  • R4 structural mortar
  • High mechanical strength
  • Easy to apply

Surface Preparation
Remove deteriorated and loose concrete until the substrate is solid, strong and rough. Any previous restoration work which is not soundly bonded should also be removed. Clean the concrete and reinforcing rods until free of dust, rust, cement laitance, grease, oils and previously applied paints by sand-blasting. Soak the substrate with water. Before repairing with Mapegrout Thixotropic allow the excess water to evaporate. If necessary, use compressed air or sponges to facilitate the removal of water.

Recommended Systems
Pour into the mixer the amount of water corresponding to the consistency required for the application. Start the concrete mixer and slowly and continuously pour Mapegrout Thixotropic into the water. If improved open-air curing of the mortar is required, add Mapecure SRA to the final mix at a dosage of 0.25% in weight of the mortar. Mix for 1-2 minutes, checking the homogeneity of the mix while scraping any unmixed powder off the sides of the mixer; remix for another 2-3 minutes. Depending on the quantity being prepared, a mortar mixer or a drilling machine with a stirrer attachment can be used. The mixing must be carried out at low speed to avoid stirring an excess of air into the mix.

Consumption
19 kg/m² per cm of thickness.

Technical Characteristics
Mapegrout Thixotropic is a ready-mixed powder mortar composed of high-strength cements, selected aggregates, special additives and synthetic fibres prepared according to a formula developed in the MAPEI research laboratories. When mixed with water, Mapegrout Thixotropic becomes an easily workable mortar with such high thixotropic properties that can be applied on vertical surfaces without sagging even in great thicknesses and with no need for formwork. If Mapegrout Thixotropic is prepared by only adding water, it must be cured under damp conditions in order to guarantee that the product's expansive properties develop completely and correctly. Once hardened, Mapegrout Thixotropic has the following properties:
  • Very high flexural and compressive strength.
  • Modulus of elasticity, coefficient of thermal expansion and permeability to water vapour similar to those of high quality concrete
  • Has high adhesion to old concrete, provided it has been soaked with water beforehand, and also to reinforcing rods, especially if they have been treated with Mapefer or Mapefer 1K.
  • High resistance to abrasion.
