This test method allows concrete to be evaluated in terms of chloride permeability,
Standards ASTM C1202 AASHTO T277 ASTM C1760 NT BUILD 492
Testing procedure to ASTM and AASHTO
While keeping 60 VDC difference between the specimen ends, current (Ampere) transmitted through the specimen is accurately measured over time calculating the total charge (Coulomb). This value relates to the specimen resistance to chloride ion penetration.
In accordance with the Standards indications, starting from the measured total charge, the instrument provides qualitative indications of the chloride ion penetrability level (from High to Negligible).
Two test cells are available depending on the specimen dimensions:

This test set, which correlates to ASTM C114 and AASHTO T260, is used for the determination of the chloride ion concentration in concrete to enable the identification of the risk of chloride induced reinforcement bar corrosion. The method involves an acid extraction of a representative drilled sample of concrete, which is then tested using an ion selective electrode and the potential compared with a calibration drawn up from a series of five known standard solution supplied with the test kit.

Carbonation is a serious problem for many reinforced concrete buildings that have been in service
Standards EN 13295
Carbonation is a serious problem for many reinforced concrete buildings that have been in service for some decades. Carbon dioxide in the atmosphere, when it comes into contact with concrete, starts off chemical reactions which tend to reduce the concrete’s protective effect on its reinforcements. It is an invisible and often underrated phenomenon because it can be easily confused with other better known ones, but it is inevitable and arduous to remedy. Carbonation is a precursory condition for corrosion, which will take place when there is oxygen and water present. Expansion due to corrosion reduces adhesion to the concrete, and is a risk for the safety factors on which the structural planning is based.
Preventing carbonation is the only possible way of preventing the decay of a reinforced concrete structure. As the decay goes on, safety is undermined and costs for restoration works may rise. In order to reduce the resources needed for, and ensure the safety of, the restoration works, taking action at the start of the carbonation process is strongly recommended. It is only awareness of the extent and evolution of the depth of carbonation which allows proper management of reinforced concrete works.
In order to evaluate the decay of a structure, it is necessary to use an efficient and effective method of analysis, which is simple and cost effective, quick and practical: CARBONTEST®.
CARBONTEST® is the innovation in establishing the depth of carbonation. It introduces a new method of sampling, which is based on collecting the powder during a perforation carried out using a common percussion drill. A collecting device (picker), designed in careful detail to optimize the powder flow, has been developed to implement the method. Proper designing of the collection container allows analysis of the powder, making use of the chemical colour change of phenolphthalein in a quick and accurate manner.
The collection tool for the sample to be analyzed is especially light, handy and portable so as to allow analysis by a single operator without needing specialized technical help.
The possibility of performing independently both the collection of the powder produced by perforation of the concrete item and the later analysis of the powdered material, simplifies the traditional analysis procedure and makes it especially cost effective and usable for a vast number of structures.
CARBONTEST® Kit complies with the provisions of the UNI 9944:1992.
This simple test allows the measurement of depth of carbonation through the surface of concrete.

Standards BS 1881:204
This method covers the determination of susceptibility to chloride and carbonation penetration into the concrete.
The apparatus can be used for:
Internal (deep permeability) test
A hole 10 mm dia., 40 mm deep is drilled and plugged leaving a cylindrical test void 10 mm dia. 20 mmhigh, situated 20 mm below the concrete surface. The time required for air and water to permeate through the test material to the void is used as an index to determine the quality of the concrete under test.
Air permeability
The air permeability test is always done first since moisture has a large effect on permeability. Following the test procedure instructions, based on the vacuum technique, the instrument timer and manometer automatically show the time in seconds for the vacuum to fall from a -55 kPa to a -50 kPa. This time is the Figg number and is a measure of the air permeability of the concrete.
Water permeability
After filling and forcing the water into the test cavity, the air is displaced out through the overflow tube . The instrument flow sensor and timer, following the test procedure, measure the time taken for the water meniscus to travel a distance of 50 mm. The time in seconds displayed on the meter, is the Figg number for water permeability.
Surface permeability test
Measurement are carried out at the surface by clamping a stainless steel chamber on the smooth surface of the concrete. A measurement of the time required for related amounts of air and water to permeate through the concrete is used as an index of the surface conditions.
