MAPEGROUT 430 ZERO

Fibre-reinforced fine-grained thixotropic mortar

MAPEGROUT 430 ZERO is a pre-blended, compensated-shrinkage mortar in powder form made from cementitious binders, selected fine-grained aggregates, special additives and synthetic fibres according to a formula developed in the MAPEI R&D laboratories. It is used to reintegrate concrete around steel reinforcement in degraded concrete structures and may be applied with a continuous-feed mortar pump.

Thanks to its particular formulation the product has excellent fatigue behaviour up to at least 300,000 cycles, which gives repaired structures a high level of resistance to cracking, including when subjected to dynamic loads induced under normal service conditions.

This particular characteristic, together with the requirements of EN 1504, helps increase the durability of elements repaired with MAPEGROUT 430 ZERO.

MAPEGROUT 430 ZERO complies with the principles defined in EN 1504-9 (“Products and systems for repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use and application of systems”) and the minimum requirements of EN 1504-3 (“Structural and non-structural repairs”) for R3-class structural mortars.

Mapei Research & Development laboratories work intensely on product formulations in order to reduce CO₂ emissions associated with our products.

Info CO₂ Fully Offset

*MAPEGROUT 430 ZERO is part of the CO₂ Fully Offset in the Entire Life Cycle line of products. CO₂ emissions measured throughout the life cycle of products from the Zero line in 2025 using Life Cycle Assessment (LCA) methodology, verified and certified with EPDs, have been offset through the acquisition of certified carbon credits in support of forestry protection projects. A commitment to the planet, to people and to biodiversity.
