synthesized and should exhibit a “hydration ability”. The CaO component should be neither too active nor inactive (it depends on the temperature of calcium carbonatedecomposition).
In this study the mixtures of cement with the sinter composed of

Lower temperatures of carbonatedecomposition confirm weaker interactions between anions and brucite-like layers. Moreover, according to chemical composition of the hydrotalcites, water molecules evolved below 250 °C from the sample AN0 come not only
Thus, in the literature, various temperature ranges of calcium carbonatedecomposition are given: 600–800 °C [ 15 , 19 ], 740–780 °C [ 16 ], 600–700 °C [ 11 ], 697–724 °C [ 24 ] and 550–1050 °C [ 12 ]. Stepkowska [ 22 ] shows that calcite decomposes
suited for data analysis) for the single-step decomposition of calcium carbonate. ICTAC used this synthetic data to test several kinetic methods [ 17 ]. The synthetic calcium carbonatedecomposition showed a 16% relative standard deviation for activation

. Traces of ammonia and water are also observed, thus suggesting the decomposition of small amounts of ammonium oxalate. At 875 °C all precursors eliminate CO 2 as a result of carbonatedecomposition.
The thermal decomposition of yttrium
attributed to refractory carbon and clays decomposition. Finally, between 700 and 800 °C, carbonatesdecomposition was observed. It could be observed that pyrolysis of SL reduces their organic matter content. In addition, biochar shows more thermally stable

pre-heating temperature for determination of SOC by the loss-on-ignition (LOI) method. Meanwhile, the region >700 °C is dominated by mineral reactions including carbonatedecomposition [ 24 ] and clay mineral degradation [ 25 ]. In non-calcareous soils
