Thermodynamic Study of Portland Cement Containing Multi-walled Carbon Nanotubes (MWCNT)

Abstract

The objective of this work is the thermodynamic study of portland cement containing multi-walled car- bon nanotubes. The measurements of the thermal expansion coefficient of the two pure samples and its nanocomposite have the same shape. The dilatometric curves contain the same number of abnormalities. Their intensity differs from sample to sample. The calorimetric study reveals a similar character between the DSC curves of the two samples, the matrix and its nanocomposite. The thermogravimetry of the two materials shows the presence of several anomalies probably linked to the phenomena of dehydration. The insertion of the multi-walled carbon nanotubes into the cement made the nanocomposite stable over a wide temperature range compared to the cement matrix
