杂散电流及氯离子腐蚀共同作用下钢纤维混凝土强度的试验
Experimental Study on the Strength of Steel Fiber Reinforced Concrete Under the Combined Effect of Stray Current and Chloride Ion Corrosion
摘要
Abstract
Based on the service environment of the subway engineering structure in the coastal water affected areas of the city,a sim-ulation device considering stray current effects was designed.The research carried out in this paper included that i)the influence on corrosion of steel fiber concrete affected by steel fiber volume fraction,conductive solution,fly ash content and rust inhibitor content is studied,and ii)the relationship between the loss rate of strength (K c )and both of NaCl solution and steel-fiber volume fraction is studied.Results show that the strength of steel fiber concrete decreases significantly under the combination of chloride ion and stray cuttent,but that this loss can be remarkably reduced by the optimal mix design.They can provide some basis for the application of steel fiber concrete in the subway engineering.关键词
