弯曲裂缝对再生混凝土构件碳化性能影响的试验研究
Experimental Study on the Effect of Bending Cracks on Carbonation Property of Recycled Concrete Element
摘要
Abstract
Concrete is a kind of brittle material, so its tensile strength is much lower than its compressive strength. There are usually some cracks in the working reinforced concrete structures. When the width of the reinforced concretes surface crack reaches a certain extent,the state of normal use and durability of the structure may directly be affected and even relate to its structure function and safety with time going. This experiment focuses on the influence of the surface curved crack on the carbonation property of recycled concrete element. This text compared with ordinary concrete carbonation tests in different strength grades of recycled concrete ( C20, C40 ) and in different crack widths (0.1 mm, 0. 2 mm). Comparing with the ordinary concrete without micro crack and recycled concrete element, the curved surface crack of recycled concrete speciments have greater impact on carbonation property than crack width.关键词
