Bulk Resistivity Accessory Set for Resipod Concrete Resistivity Meter

Bulk Resistivity Accessory Set for Resipod Concrete Resistivity Meter

The Bulk Resistivity Accessory Set is designed for use with the Resipod Concrete Resistivity Meter to measure the electrical resistivity of concrete specimens. Concrete resistivity testing helps evaluate durability, permeability, and corrosion risk in reinforced concrete structures.

Concrete naturally resists the flow of electricity. By measuring this resistance, engineers can better understand the quality and long-term performance of concrete.

Why Measure Concrete Resistivity?

Concrete resistivity is a key indicator of chloride penetration and steel corrosion risk. Lower resistivity values often indicate higher corrosion potential due to increased ionic movement.

This test is commonly used to:

• Assess concrete permeability
• Estimate chloride diffusion
• Predict reinforcement corrosion
• Support maintenance and repair decisions

Electrical resistivity testing aligns with standards such as ASTM C1202 and ASTM C1556.

What Is Electrical Resistivity?

Electrical resistivity measures a material’s ability to resist electric current. In concrete, it is influenced by:

• Moisture content
• Cement type
• Aggregate composition
• Temperature

Bulk electrical resistivity is typically measured in a laboratory using concrete cylinders. This method provides consistent and repeatable results for durability evaluation.

Bulk Resistivity Testing with Resipod

The Bulk Resistivity (BR) Method is performed on 4 x 8 in (102 x 203 mm) concrete cylinders. Electrical plates with conductive inserts are placed on each end of the specimen and connected to the Resipod meter.

To ensure accurate results:

• Probe reservoirs must be filled with water
• Plates must maintain full contact with the specimen

An optional variable-spacing probe improves flexibility and measurement accuracy.

What’s Included in the Accessory Set

The Bulk Resistivity Accessory Set includes:

• Electrical measurement plates
• Conductive foam inserts
• Instrument stand with cable connections
• Cables for meter connection
• Soil resistivity test box
• Large soil box

The Wenner probe is also available for surface resistivity testing, which is ideal for field evaluations of chloride-ion penetration.
