Description:

A medium strength high build repair mortar meets EN 1504-3 R3 classification.

Technical Characteristics :

Mapemortar HB R3 Zero is a premixed powder mortar composed of cement, graded aggregates and special
additives from a formula developed in the Mapei research laboratories.
When mixed with water Mapemortar HB R3 Zero forms an easy to apply high build mortar that can be
applied without slumping even in substantial thicknesses on vertical surfaces without the aid of formwork. When fully cured Mapemortar HB R3 Zero:

• has a modulus of elasticity, thermal expansion coefficient and permeability coefficient similar to medium
  strength concrete;
• has excellent adhesion to existing concrete surfaces providing they have been pre-soaked and still damp with clean water;
• reinforcing bars should be treated with Mapefer or Mapefer 1K Zero.

If Mapemortar HB R3 Zero is prepared by only adding water, it should be cured under damp conditions in order to guarantee that the products expansive properties develop correctly and completely. Mapemortar HB R3 Zero 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 structural mortars of class R3.
