The study involves properly blending fly ash with cement kiln dust to create a cementitious material in which the material deficiencies will be converted into benefits. The activation process chosen, in order to facilitate and enhance hydration of the two materials, is mechanical grinding.
The decalcification process removes the mineralized part of the dental hard tissues, making the histologic examination of enamel-associated tissues less than optimal. The cutting-grinding technique allows preparation of histologic slides with well preserved dental hard tissues together with their surrounding soft tissue components.
