Abstract:
Construction issues attributed to Type IL cement have included reduced bleeding and extended setting time, which can lead to surface scaling. These issues are not necessarily due to the use of Type IL cement. Commonly used SCMs, slag cement, excessive entrained air, or finely ground Type I/II cement can also reduce bleeding and lead to scaling. This article focuses on how petrographic examination can help determine the probable causes of scaling in exterior flatwork.
