Project description

The objectives of this research are to (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.
