Abstract

3 kinds of cement concretes are listed as follow: normal concrete, air-entrained concrete with 4% air content, concrete with 15% fly ash and 4% air content. Experiment methods of environmental coupling effect were designed. Model had been proposed in order to classify ink-bottle pore. Contents and shapes of ink-bottle pores had been compared among all kinds of ink-bottle pores in treatment group, control group samples. Result shows that ink-bottle pore content and shape are different between concretes corroded by environmental coupling effects and ones corroded by single environmental factor. Ball shape ink-bottle pore with 3~50nm pore size diameter makes an important role for stability of concrete. Ball shape ink-bottle pore is stronger than ellipsoid one. The more flat ellipsoid shape ink-bottle pore is, the weaker it is.
