Cement paste surface roughness analysis using coherence scanning interferometry and confocal microscopy

Epoxy resin‐cement paste composite for wellbores: Evaluation of chemical degradation fostered carbon dioxide

“…[9][10][11] Rimmelé et al 52 found that porosity of Portland cement exposed to CO 2 -rich fluids varies from the edge to the middle of the sample: 15-20% in the middle to 25-35% in the edge. According to Apedo et al, 53 porosity and pore space geometry are very important properties that are related to the material structure, influencing surface roughness and water content in the cement. Moreover, AFM results show that the addition of epoxy resin in the cement paste does not significantly change roughness of the non-degraded surface (Figs 5(b) and 6(b)) when compared to that of pure cement paste ( Fig.…”

Structure light telecentric stereoscopic vision 3D measurement system based on Scheimpflug condition

“…The traditional contact-detection method, for example, Micro-CMM [1,2] has not satisfied the requirements of fast, highly accurate, and non-destructive detection in the microelectronics manufacturing industry. Therefore, many scholars-both domestic and foreign-have proposed non-contact optical measurement methods, such as confocal microscopy [3,4], white-light interferometry [5,6], and microscopic fringe projection [7][8][9][10]. Even if the resolution of confocal microscopy and whitelight interferometry reach nano-level, the measurement range is merely several millimeters.…”

Geometrical roughness analysis of cement paste surfaces using coherence scanning interferometry and confocal microscopy

“…The factor that is studied in this paper is the surface roughness. To characterize cementitious material surfaces, standard roughness parameters are often used with topographic reconstruction techniques such as confocal microscopy [1,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] and atomic force microscopy (AFM) [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”

“…More recently, [1] have introduced a multiscale analysis of cement paste surface roughness. Two new optical profilometry techniques, coherence scanning interferometry (CSI) and scanning confocal microscopy (SCM) have been used in the surface reconstruction.…”

“…Although CSI showed its performance in the characterization of various kinds of materials [48][49][50][51][52][53][54][55][56][57][58] its use remains relatively unexplored in the field of cement-based materials [1,59,60].…”
