Perma2 Rapid Chloride Permeability Test Cell

Perma2 Rapid Chloride Permeability Test Cell

The Giatec Perma2™ is an advanced laboratory testing device engineered to precisely measure the resistance of concrete to chloride ion penetration, a critical factor in determining concrete durability. This state-of-the-art tool performs the Rapid Chloride Permeability Test (RCPT) and is fully compliant with leading industry standards, including ASTM C1202, AASHTO T277, and ASTM C1760. By providing accurate data on concrete's electrical resistance, the Perma2™ is essential for predicting service life, informing structural design, and executing durability-based quality control for modern concrete structures. It is the only RCPT apparatus on the market that is electrically certified (UL/CSA/CE) for safe operation in concrete labs.

How It Works: The Perma2™ applies a controlled voltage across a concrete specimen and measures the total electrical charge that passes through it over a six-hour period. A lower charge indicates higher resistance to chloride penetration, signifying more durable concrete. This data is invaluable for assessing the effectiveness of supplementary cementitious materials (SCMs) like fly ash, slag, and silica fume in enhancing concrete performance.

Key Features:

• High Precision and Compliance: Delivers results with ±0.1 mA accuracy, strictly adhering to ASTM and AASHTO test specifications.
• Efficient Multi-Sample Testing: Features four independent channels, allowing for the simultaneous testing of up to four concrete samples.
• Automated Test Control: Integrated temperature sensors automatically monitor and regulate the solution temperature in each cell to ensure test accuracy.
• User-Friendly Stand-Alone Operation: A large, clear display and intuitive interface allow for easy test setup, monitoring, and data logging (with flexible intervals from 1 to 10 minutes) without needing a constant PC connection.
• Enhanced Data Management: Includes optional PC software with a simple USB connection for advanced test control, real-time data visualization, and comprehensive report generation.

Primary Applications:

• Durability Assessment: Measures concrete's resistance to chloride ion penetration as per ASTM C1202 and AASHTO T277.
• Quality Control: Facilitates performance-based quality control by verifying the consistency and durability of concrete batches.
• Service-Life Modeling: Provides crucial data for estimating chloride diffusion and migration coefficients, enabling accurate service-life predictions for new and existing structures.
• Material Characterization: Determines the bulk electrical conductivity of concrete in accordance with ASTM C1760.
