Researchers have developed a nondestructive and noninvasive optical technique that can determine the setting times for various types of cement paste, which is used to bind new and old concrete surfaces. The new method could aid in the development of optimized types of cement with less impact on the environment.

“Our noninvasive optical method characterizes and determines the setting time of cement, which is a very important parameter for the construction industry,” said José Ortiz-Lozano, a membe
