Project description

The objectives of this research are: (1) evaluate the quality of various clay sources available in Florida in terms of their chemical and mineralogical composition and amorphous content through the use of x-ray fluorescence and x-ray diffraction techniques; (2) explore different calcination temperatures and accompanying phase transformation for various clay samples through the use of x-ray diffraction or other techniques; (3) evaluate the reactivity of calcined pozzolanic materials in combination with ordinary Portland cement through the use of mortar compressive strength.
