The Performance Research On New Style Constructional Material "CongealingStone"

Since Congealing stone, as one kind of new building material, has been invented, somebody have some kinds of question to it. It is not scientific to think that it is good or bad absolutely, but it is feasible to carry on the appraisal to its each aspect performance. In line with one kind of scientific manner, a comprehensive research on Congealing stone various aspects performance is done under teacher's instruction .Regarding Congealing stone performance research mainly includes two aspects, namely the ordinary physical mechanics performance and the durability quality .To contrast the Portland cement and the Slag cement in each aspect, the performance of the Congealing stone is showed completely. The ordinary physical mechanics performance of Congealing stone mainly includes the basic working performance and its stress'law of development ; The durability quality including the anti- chloride ion penetrating ,the anti- sea water corroded, the contraction performance and the steel bar in concrete rusting. The research indicated that, Congealing stone to need less water, to flow in a big way, the higher stress and so on; But compares with the Portland cement,Congealing stone also have some flaws, such as the worse volume stability, the bigger contraction, and the lower stress certainly retracting in the later period.Based on the innovation thought, when studying in the Congealing stone, some unique testing methods are proposed on the research, and have made the thorough research to these methods scientific natures. The CRS method which is used to test Congealing stone contraction performance, is the newest method in domestic, although it still must be to improve and consummate, the method is feasible, scientific, and more simple and convenient,compared with other present testing methods in domestic.Finally some preliminary discussions about the Congealing stone hydrated hardening mechanism is made by unifying the existing some research, using some advanced testing methods, and try to make some reasonable explanations about Congealing stone performance displayed from microscopic.
