Description
Technical field
The utility model relates to the building materials technical field of measurement and test, particularly a kind ofly can measure the testing concrete performance device of mixing swelling agent at the construction field (site) fast.
Background technology
Under the big academician's expansive concrete guide of theory of Wuzhong, the expansive concrete of mixing swelling agent has obtained fast development in China, and the Application and Development of swelling agent has obtained very big achievement.The situation that the product technology level is lower though China's swelling agent through the development of two more than ten years, is not broken away from as yet, market is relatively more chaotic.Trace it to its cause is that swelling agent in use lacks the detection method of getting instant result.The expansion character that the test method that we adopt GB23439-2009 " cement expansive material " to provide is at present tested cement expansive material.Wherein the standardization appendix A has been stipulated the limited expansion rate test method, comprises vertical limiter size and surveying instrument, testing laboratory's temperature and humidity, and the examination system is equipped with, and examination body examination length and result calculate and analyze; Informative annex B has stipulated to mix the concrete confined expansion and the shrinkage test method of expansion, comprises vertical limiter size and corresponding surveying instrument, testing laboratory's temperature and humidity, the making of examination body, the survey length of examination body and maintenance and result's analytical calculation.These two kinds of methods are used for estimating cement expansive material and the concrete expansion character of mixing swelling agent; Has scientific rationality; But because its test apparatus accuracy requirement is high, experimental test control long, process of the test in the length of time is relatively complicated; Can only carry out in the detection unit that qualification is arranged, can not be used for the quick test of working-yard.
Therefore; Before measuring limited expansion rate; In order to judge whether swelling agent or concrete have expansion character fast, GB23439-2009 informative annex C has also stipulated a kind ofly to be used to detect cement expansive material and to mix swelling agent concrete expansion character accelerated test procedures.A kind of is that the cement slurry of mixing swelling agent that stirs is filled with the beer bottle that volume is 600ml, the expansion character of the time qualitative discrimination cement expansive material in crack occurs through the sight glass beer bottle; Another kind is to get at the scene about the concrete 400ml that mixes swelling agent that stirs, and in the glass beaker of the 500ml that packs into, the concrete expansion character that the time qualitative discrimination in crack is mixed swelling agent occurs through the sight glass beaker.Seeing that the essential purpose of beer bottle is used for holding beer; The quality of the employed beer bottle of beer producers of various brands varies certainly; Even test expansion character with a kind of swelling agent with the employed beer bottle of the beer producers of same brand; The time that the crack appears in beer bottle also has very big otherness; Test the expansion character with a kind of swelling agent with the employed beer bottle of the beer producers of commercially available different brands, the temporal differences property that the crack appears in beer bottle is more remarkable.When testing the concrete expansion character of mixing swelling agent with glass beaker, the time that the crack appears in glass beaker is generally after 3 days, and the discreteness as a result of same group of test is very big, can not play the purpose that the swelling agent expansion character is judged in real test fast.In addition, the use of glass beaker can only be disposable in the process of the test, can not repeat repeatedly to use, and causes the certain economic waste.
Summary of the invention
The utility model is to existing test method deficiency separately; Expansion character method for rapidly testing to cement expansive material is explored; And design a kind of concrete expansion character proving installation; The concrete expansion character that it can scientific and reasonable at the construction field (site) quick measurement mixes swelling agent, and can carry out Comparative and Quantitative Analysis to the expansion character of variety classes swelling agent, control is mixed the concrete quality of swelling agent and offer help.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of concrete expansion character proving installation comprises:
