Effects of High Temperature on the Microstructure of Cement Mortar

Abstract:

The objective of this study was to examine microstructural changes of cement mortar due to elevated temperature from 105 to 500°C. Changes at the meso and microscopic levels were followed by nitrogen adsorption desorption isotherms, from which the pores size distributions and specific surface areas were determined. The results show a decrease in volume of micropores and an increase in volume of mesopores which reflect clearly the shrinkage and structural transformation of the calcium silicate hydrate due to high temperature.
