Photonic Based Refractive Index Sensor for Portlandite Monitoring in Civil Structure

In this paper, photonic based refractive index sensor is proposed to monitor portlandite in civil structures. Portlandite is oxide mineral that naturally occurs from calcium hydroxide (Ca(OH) 2 ) and calcium analogue of brucite (Mg(OH) 2 ). Portlandite creates a problem in concrete in terms of corro...

Description
Summary:In this paper, photonic based refractive index sensor is proposed to monitor portlandite in civil structures. Portlandite is oxide mineral that naturally occurs from calcium hydroxide (Ca(OH) 2 ) and calcium analogue of brucite (Mg(OH) 2 ). Portlandite creates a problem in concrete in terms of corrosion and spalling. The proposed sensor is designed to detect the presence of portlandite by measuring Ca(OH) 2 and Mg(OH) 2 chemicals. It is observed that the proposed sensor produces a wavelength shift of 0.008μm and 0.005μm for Ca(OH) 2 and Mg(OH) 2 respectively.
