摘要: The chemical composition of the pore solution expressed from matrices simulated borate liquid waste (containing H3BO3, Na2SO4, Na2HPO4 and Ca3(PO4)2) pozzolanic cement (Spanish type IV-35) changes caused by leaching over 180 days in deionized water at temperatures 20 40°C were studied. was carried out according to ANSI/ANS-16.1-1986 test. In addition, change solid phase characterized X-ray diffraction, infrared spectroscopy scanning electron microscopy.
