high resistance to sulfate & chloride . Tricalcium aluminate 3CaO Al 2 O 3 C 3 A 6 12 First compound to hydrate, highest heat of generation, reactive with soils and water containing sulfate. Undesirable since formation of calcium sulfoaluminate may cause expansion during setting. Does not contribute to strength. Chemical composition of Portland Cement
