FBG Sensing Technology for the Temperature and Strain Monitoring of Cement Solidification Process
The use of fiber grating sensing technology has grown significantly in recent years, due to its high precision and accuracy in measuring physical parameters such as temperature and strain. In scientific research, it has become an essential tool for monitoring various material properties under extreme conditions. In this article, we will discuss the problems that fiber grating sensing technology can solve, and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the temperature and strain monitoring of cement solidification process .
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Analysis of Demand for Temperature and Strain Monitoring of Cement Solidification Process:
In the field of scientific research, the cement solidification process is of significant interest, as it involves complex chemical and physical reactions. Accurate temperature and strain monitoring during the cement solidification process can help optimize the process and improve the quality of the final product. For example, by monitoring the temperature and strain, researchers can gain insight into the hydration process, which can affect the strength and durability of the cement.
Why Measuring the Strain, Temperature, and Other Aspects of the Cement Solidification Process is Needed:
Measuring the temperature and strain during the cement solidification process provides valuable information that can help optimize the process and improve the quality of the final product. The hydration process of cement is exothermic, meaning that it releases heat. The rate of heat release affects the rate of hydration, which in turn affects the strength and durability of the cement. By monitoring the temperature and strain, researchers can gain insight into the hydration process and adjust the process accordingly to achieve the desired properties.
Difficulties in Monitoring the Temperature and Strain of the Cement Solidification Process：
Monitoring the temperature and strain during the cement solidification process presents several challenges. The high temperatures and harsh chemical environment can cause conventional sensors to degrade or fail. The conventional sensors may also interfere with the hydration process, leading to inaccurate measurements. Additionally, the cement solidification process can occur over an extended period, making continuous and reliable monitoring challenging.
What Problems can be Solved by FBG Sensing Technology:
Fiber grating sensing technology offers several advantages over conventional sensing methods. The fiber optic sensors are immune to electromagnetic interference, making them suitable for use in harsh environments. They are also small in size and can be embedded in the cement mixture without affecting the hydration process. Furthermore, fiber grating sensing technology can provide continuous and accurate monitoring of temperature and strain over an extended period.
