Testing of concrete — Part 12: Determination of the carbonation resistance of concrete — Accelerated carbonation method
Specifies a method for determining carbonation depth, similar in principle to the field/lab method in IS 13735.
Key Differences
≠IS 13735 is a single consolidated standard compiling multiple durability test methods (permeability, absorption, carbonation, etc.), whereas international practice (ASTM, EN) typically dedicates a separate standard for each individual test method.
≠For chloride resistance, IS 13735 specifies a long-term ponding test measuring chloride profiles. The widely used international equivalent, ASTM C1202, uses a rapid, indirect electrical measurement (RCPT) to assess chloride permeability in just 6 hours.
≠The water permeability test duration in IS 13735 is 96 hours, which differs from the 72-hour duration specified in its European equivalent, BS EN 12390-8.
≠IS 13735 provides indicative classifications for concrete quality based on test results (e.g., 'Good', 'Moderate', 'Poor' for permeability), while many modern EN test method standards strictly describe the procedure, leaving classification to separate specification standards like EN 206.
Key Similarities
≈The fundamental principle of the water permeability test, involving applying water under pressure to one face of a concrete specimen and measuring penetration depth, is conceptually identical to methods in BS EN 12390-8 and the older DIN 1048.
≈The basic methodology for the water absorption test—drying a specimen to constant mass, immersing in water, and measuring mass gain—is a common principle shared with BS 1881-122 and ASTM C642.
≈The use of a phenolphthalein indicator solution sprayed on a freshly broken concrete surface to measure the depth of carbonation is the standard, universally accepted technique used in IS 13735 and international practices.
≈The Initial Surface Absorption Test (ISAT) apparatus and principle described in IS 13735 are almost identical to those in the British standard BS 1881-208, including the specified 200 mm head of water.
