摘要：
The objective of this study was to examine microstructural changes of cement mortar due to elevated temperature from 105 to 500 degrees 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.
