“…Some authors simply concentrated on a single treatment temperature [ 5 , 6 ] and others approached only a few properties, namely the fresh behavior and the mechanical strength [ 4 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. Other studies were dedicated to the incorporation of varying percentages of RC in mortars and concrete [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Furthermore, results reported in the literature are contradictory, reflecting the lack of knowledge of these poorly explored new binders [ 1 ].…”

“…Por outro lado, ao contrário do observado por vários autores [2,5,6], nenhum pico de cal livre é detectado na Figura 7, o que pode ser explicado pela combinação de três fatores. O primeiro fator é que a portlandita desidroxilada pode preservar parcialmente a estrutura cristalina mesmo com a perda de água quimicamente combinada e, então, apresentar espectro de DRX similar ao Ca(OH) 2 não decomposto [5].…”

“…Ademais, na amostra aquecida a 750°C, picos adicionais de silicatos dicálcico e tricálcico, aluminato de cálcio e ferroaluminato de cálcio são detectados no intervalo de 29-35° 2θ [2,[4][5][6], de maneira similar ao verificado no cimento Portland anidro. Isto mostra que a recuperação dos compostos anidros do cimento hidratado se inicia em temperaturas na ordem de 750°C, o que poderia viabilizar a reutilização desse cimento como material de construção.…”
