Specifications:

• The pore structure in turn depends on other factors such as the mix design, degree of hydration, curing conditions, use of supplementary cementitious materials, and construction practices.
• The rapid chloride-ion permeability test (rcpt) is designed to assess the resistance of concrete to the penetration of chloride ions, an indicator of its permeability.
• Therefore, wherever there is a potential risk of chloride induced corrosion, the concrete should be evaluated for chloride permeability.
• Complete with tools kit.

Complete rapid chloride ion permeability tester includes the following items:

• RCPT test apparatus with 4 port (230~250 V AC power supply).
• Moisture trap.
• Temperature probe.
• 300mm vacuum desiccator.
• Vacuum pump with gauge.
• Plexiglass chambers 4 pairs.

Rating of chloride permeability of concrete according to the rcpt test apparatus is as below:

• Rating: Typical concrete type permeability coulombs.
• Negligible: < 100 polymer-impregnated concrete, polymer concrete.
• High: >4000 high w-c ratio (> 0.6) conventional PC concrete.
• Low: 1000 to 2000 low W-C ratio (< 0.40) conventional PC concrete.
• Very low: 100 to 1000 latex-modified concrete, internally sealed concrete.
• Moderate: 2000 to 4000 moderate W-C ratio (0.40 to 0.50) conventional PC concrete.
