The phenomenon that system chemical balance destroys and concrete system performance is caused to deteriorate.Concrete is because material source is extensive, cost performance is high
The advantages that strong with plasticity and be widely used in current field of civil engineering.However, concrete structure often faces serious carbon
Change problem causes the basicity of concrete system to reduce, rebar surface Damage of Passive Film so that concrete structure durability and
Service life reduces.Therefore, concrete carbonization has great influence to reinforced concrete structure durability and service life.For
The most intuitive assessment of carbonization, the as measurement of concrete carbonization depth.
So far, measuring method used in carbonation depth mainly includes following four kinds of methods: 1) phenolphthalein indicator method；Its
Test object are as follows: the measurement region pH > 10；Its measuring mechanism are as follows: 1% phenolphthalein solution of spray measures transformation region in concrete splitting face
Length of field；Advantage: convenient and efficient to obtain approximate carbonation depth；Disadvantage: carbonization face is not obvious enough, and there are certain errors for measured value.
2) thermal analysis system；Its test object are as follows: measurement calcium hydroxide and calcium carbonate content；Its measuring mechanism are as follows: sample is heated to 900
DEG C, the two content is calculated by heating front and back calcium hydroxide and the variation of calcium carbonate heat content；Advantage: it can be carbonized with evaluation portion
Area；Disadvantage: can only judge the carbonization of calcium hydroxide, cannot judge the carbonization of hydrated calcium silicate.3) X-ray phase analysis process；Its
Test object are as follows: the mineral species of measurement carbonization front and back；Its measuring mechanism are as follows: X-ray diffraction is carried out to sample, reference standard is spread out
Figure is penetrated, judges the structure and title of carbonization front and back mineral；Advantage: can be with evaluation portion carbonizing zone；Disadvantage: to amorphous identification
More difficult with analyzing, accuracy of quantitative analysis is not high.4) infra-red sepectrometry；Its test object are as follows: measurement carbon dioxide and calcium carbonate
Content；Both its measuring mechanism are as follows: determined with the C-O key in the C=O key and calcium carbonate in infrared spectroscopy survey carbon dioxide
Amount；Advantage: characteristic is high, and the physical state for the sample that is not put to the test influences；Disadvantage: degree sample quality requires high.
In conclusion phenolphthalein mensuration precision is too low, rear three kinds of methods operation is not convenient enough and cost is relatively high, at present
For, most experimenters when measuring concrete carbonization depth using 1% phenolphthalein reagent be sprayed on carbonization splitting surface into
Row measurement, measurement effect are illustrated in fig. 1 shown below with drawback.
From fig. 1, it can be seen that there are larger discrepancy with practical concrete carbonization depth for the concrete carbonization depth surveyed of phenolphthalein, and
It is 9-12 or so to the pH value impacted in concrete to steel bar corrosion rate, thus phenolphthalein test result and does not have abundant
Practical significance.
Reagent and its using effect are measured from existing concrete carbonization depth it is found that using only mixed with single performance
Solidifying soil carbonation depth measurement reagent is difficult to ensure the accuracy of test result.Therefore, a kind of concrete carbon being applied in combination is developed
Needed for change depth measurement reagent can meet actual measurement to a certain extent, there is good economy and environmental benefit.
