Abstract: At present, polymers, fiber and other additives are added to the cement based materials by researchers at home and abroad for the purpose of dealing with the difficult problems occur in practical application, such as low tensile strength, small ultimate elongation, remarkable brittleness, easy to crack and other issues. In this paper, the shrinkage deformation of cement based materials are classified into four types upon the analysis of shrinkage reasons, then the inhibitory effect and its mechanism of polymers fiber for cement based material are investigated.

Abstract: The corrosion weight loss method and polarization curve measurement were conducted to study the effects of the complex inhibitor of sodium tungstate and urotropine on the corrosion of 304 stainless steel in the 3.5% NaCl solution. The results indicated that the complex inhibitor has good synergistic inhibitory effect for stainless steel in the NaCl solution. Combining sodium tungstate and urotrpine at a total concentration of 500 mg/L, when the mass ratio of sodium tungstate to urotrpine was 7:3, the inhibitory effect was optimum. In addition, the probable inhibitory mechanism was analyzed.
