The bonding status and chemical environment of SiO4 and AlO4 tetrahedras of three types of geopolymeric products were systematically investigated by infrared spectroscopy.The relationship between amorphous geopolymeric products and zeolite crystals with the same overall chemical compositions was also discussed.The infrared evidence shows that SiO4 tetrahedra is partially bonded by AlO4 during the hydration process ofgeopolymeric cement.The two types of tetrahedras jointly construct the three dimensional framework structures of the geopolymeric products.The mutual transformation between geopolymeric products and corresponding zeolite crystals will take place once the reaction condition is suitable,which reveals that the nature ofgeopolymeric products are probably the amorphous equivalent of the corresponding zeolite crystals.
