Synopsis

Fresh concrete may be susceptible to plastic shrinkage cracking. Cracks that develop at an early-age can significantly impact the durability of concrete structures. This study has developed a quantitative approach to determine the efficiency of fiber reinforcement for plastic shrinkage crack reduction. A semi-automated image analysis technique was used to process digital images of surface crack widths. Statistical analysis methods were used to determine the repeatability of the test as a proposed standard plastic cracking test method. Finally, the impact of premature cracking on the corrosion of steel reinforcement was quantitatively assessed.

About the Author

Chengqing Qi was born in 1972. He studied at Southeast University (China) in the area of cement and concrete materials, before joining Purdue University for Ph.D. study. He works on microscopy and petrography of cementitious systems,durability of concrete, and hydration of cementitious materials.
