煤渣粉掺量对再生混凝土氯离子扩散系数的影响
Influence of Coal Power Amount on Recycled Concrete Chloride Diffusion Coefficient
摘要
Abstract
The influence of activation coal power content and corrosion time on recycled concrete chloride diffusion coefficient(Dt)was studied,the free chloride of recycled concrete in 3.5％NaCl solution at different time was measured,and the value of Dt was computed.The result shows that: recycled concrete chloride diffusion coefficient(Dt)is decreased with the increasing of corrosion time.Dt,recycled concrete chloride diffusion coefficient at 28 d(D0)and time-dependent coefficient(n)are all first decreased then increased with the increasing of coal power content,and the minimum exists at 30％content of coal power.The relationship between Dt and corrosion time is a power regression,there is quadratic hyperbolic function relation between D0 or n and coal power content.The equation of Dt with activate coal power content and corrosion time is derived.The chloride diffusion coefficient of coal power recycled concrete is predict in the marine environment by use of this equation.关键词
