| Popis: | In this work, a nondestructive and noninvasive technique, based on laser technology and the use of the Kubelka–Munk model to calculate the dynamic behavior of the cement paste from the diffuse reflection properties of both cement components and hydration products, is proposed. Also, the Powers–Brunauer model is used to explain this behavior during the first 9 h of the hydration process. This method allows us to obtain the initial and final cement setting times from the diffuse reflection measurements. |
