To address these issues, this study developed a fluorescent fiber optic sensor for non-destructive detection of chloride ion concentration in cement-based materials.
This work introduces two new methods for monitoring cement paste carbonation in real time that have been validated through the accelerated
In this work, a multimode fiber was embedded in cement paste for real-time monitoring of cement paste water vapor sorption.
Measuring Water Vapor Sorption Hysteresis of Cement Paste through an Optical Fiber Sensor Pedro M. da Silva 1,2, Luís C. C. Coelho 1,* and José M. M. M. de Almeida 1,3
Traditional manual filling methods lead to inconsistent paste usage, higher material costs, and quality risks. This study introduces a PLC-based flow
Compliant fiber-optic micro-strain sensors have been used for measurement of chemical as well as autogenous shrinkage of cement pastes with different water-cement ratios.
Plan to attend SPIE Photonics West, the leading global conference and marketplace for lasers, biomedical optics, quantum, biophotonics technologies,
Originality/value A new method for measuring the paste flow is presented, which is based on the principle of optical fiber Doppler. The method has the advantages of convenient installation, high
In this work, a multimode fiber was embedded in cement paste for real-time monitoring of cement paste water vapor sorption. Changes in the reflected light intensity due to the build-up of water in the
The distributed optical fiber sensors are embedded in a cement paste cantilever. A controlled deflection is applied at the free end of it, and the strain is measured. The results are
Water vapor sorption is a powerful tool for the analysis of cement paste, one of the most used substances by mankind. The monitoring of
