Service life and durability assessment of reinforced concrete structures

The construction industry is rapidly moving towards performance based specifications for concrete durability of new structures; at the same time the assessing of service life of actual reinforced concrete elements is being a subject of increasing concern in the industry. Half-cell potential, concrete resistivity and concrete cover air permeability are the main and most widely accepted indicators of likelihood of corrosion and estimated durability of a concrete structure.

Proceq’s Profometer Corrosion, Resipod and Torrent instruments are designed and manufactured to assess the durability of concrete structures by measuring corrosion potential, concrete resistivity and permeability.

Models

Profometer Corrosion

Resipod

Torrent
Description Advanced half-cell measuring instrument for on-site mapping of the corrosion potential. Dedicated software for assisted measurements with rod and wheel electrodes. Statistical software for immediate data interpretation. A complete solution for measuring the electrical resistivity of concrete both in the laboratory under controlled conditions and on site. Standard fixed spacing surface Wenner probe with variable spacing and bulk resistivity accessories. Air permeability tester for the on-site assessment of the concrete quality by mean of the unique two-chamber vacuum cell principle.
