ABSTRACT: In light of the highly demanding cement market in Jordan, comprehensive
studies should be undertaken to investigate the properties of the different
cement types. This paper studies the Dynamic modulus of elasticity (DME) at 2,
7 and 28 days in mortars using six cement Jordanian types with CaO contents
less than that of the ordinary Portland cements. It was found that the DME has
strong relation with compressive strength. At the age of 28 days the mortars
had some different values of DME. One important result of our work is that DME
at the age of 28 days can be derived from those of the two days mixes. To
account for the differences in dynamic modulus of elasticity with time, it is
highly recommended to study in detail the mortars petrography under the light microscope.
Using the scanning electron microscope (SEM), usually with attachment for
chemical analysis at the crystal scale, in addition to X-ray diffraction
technique may help characterization of the cement phases qualitatively and
quantitatively.
