Abstract:
The microstructure of concrete is its basic anatomy, which controls its properties and performance. Petrography, which is a discipline of geology, is the study of the microstructure of rocks, including man-made rock, which encompasses the composition and condition of concrete. Petrography not only allows the diagnoses of the causes of concrete deterioration, but also provides valuable information to engineers who can then choose an appropriate repair strategy. In this article, I provide some case studies to illustrate the importance of petrography in the concrete repair industry.
