Mapegrout T60 ME is a single component, thixotropic cement-based mortar formulated to compensate for hygrometric shrinkage. Mapegrout T60ME is composed of pre-blended hydraulic binders, synthetic polyacrylonitriVBVle fibers, organic corrosion inhibitors, selected aggregates and special water-retaining additives. Under extreme climatic conditions and/or where correct or adepuate curing cannot be maintained, the addition of Mapecure SRA is hughly recommended in order to ensure the required performance criteria are attained. Mapecure SBA is considered a technologically advanced additive system thathas the capabilityof slowing down the evaporation rate of the mixing water thereby promoting the efficiency of the hydration process. The addition of Mapecure SRA in proportions of up to 0.25% by weight has the abilityto reduce drying shrinkage between20% and 50%. Where concrete repairs are required, particularly as a result of chloride-induced corrosion of the reinforcing steel. the incorporation of Mapeshield I internal galvanic protection anodes. should be considered or Mapeshield E. external galvanic protection sheet which can be used to protect both repaired and unrepaired areas. Please consult the relevant technical data sheet in order to correctly select the type, size and spacing of the anodes system. Mapegrout T60 ME meets the requirements defined by EN 1504-9 (“Products and systems for the protection and repair of concrete structures — Definitions, requirements, quality control and evaluation of conformity — General principles for the use of products and systems") and the minimum requirements claimed by EN 1504-3 ("Structural and non structural repair") for stmctural mortars of class R4.
Repairs to both new and old conrete structures or reinforced concete elements subject to aggressive atmospheric conditions including chloride and sulphate attack.
