Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of digital carbonation depth measuring instrument.
Background technology
Concrete carbonization value refers to from the inside carbonation depth of concrete surface.Concrete carbonization refers to the Ca (OH) in concrete
2with CO in air
2, molten CO in water
2or other acidic materials reaction becomes CaCO
3and lose alkaline process.After carbonization, concrete intensity should improve, rather than reduce, so should revise this influence factor while adopting lossless detection method to detect concrete compressive strength, concrete carbonization depth is an important indicator of concrete intensity with rebound method.The detection of carbonation depth is widely used is for a long time mechanical indicating pointer direct-reading carbonation depth dip stick, and this pit gauge application lever amplification principle, indicates numerical value by mechanical indicator.In actual use, the depth value of manual read's fetch pointer indication, its numerical value of manual record, then carry out drawing measured concrete carbonation depth after artificial treatment according to relevant technologies index.From practical situations, mechanical indicating pointer carbonation depth chi inevitably exists artificial reading error larger, and each link easily produces personal error, and can not meet the accuracy requirement of measuring for carbonation depth in the national rule of up-to-date release.
