| Abstract | Macro-Defect-Free (MDF) cements using the blends of sulfoaluminate ferrite belite (SAFB) clinkers and ordinary Portland cement (OPC) in mass ratio 85 : 15 and hydroxypropylmethyl cellulose (HPMC) or polyphosphates (poly-P) were subjected to various moist atmosphere to investigate their environmental deterioration. Their thermal decomposition studies were also carried out before and after moisture attack. The effect of individual relative humidity (RH) on moisture resistance of MDF cements is more intensive than the effects of composition of MDF cements or duration of the original MDF cements synthesis. There are three main temperature regions on TG curves of both series of MDF cement samples (before and after moisture attack). In the inter-phase section of MDF cements, the content of classical cement hydrates (CSH, gypsum, AFm and AFt phases) decomposing by 250 oC is increased, while the content of cross-links section and Ca(OH)2 with typical thermoanalytical traces in temperature range 250 - 550 oC remains almost identical before and after moisture attack. In the temperature range 550 - 800 oC, decomposition of CaCO3 is occurred. Some important applications of MDF cements also have been reviewed in this work*. |
