Role of Alkalis and Sulfates of Portland Cement on Durability of Florida Structures (Summary)

摘要

The purpose of this study was to evaluate how different SO3 and alkali levels affect Portland cement structures in Florida's environmental conditions. Researchers first performed chemical analyses of five types of Portland cement commonly used in Florida. Samples cast from the cements were evaluated for strength and durability under a variety of conditions. The researchers divided the samples into groups that were subjected to lime water solutions, continuous and intermittent salt water immersion, and high temperature and ambient temperature curing. They used scanning electron microscopy, x-ray diffraction, and optical microscopy to examine the test samples.
