11-06-2020The thermal decomposition of MgCO 3 (magnesite) is performed at much lower temperatures between 402 and 550 C depending on the CO 2 partial pressure [1,6,7] . Since the MgCO 3 /CaCO 3 ratio varies with the type of limestone, the decomposition temperature does not remain constant and therefore must be determined for every type of limestone.

Endothermic reactions have positive enthalpy values (+ΔH). An equation which shows both mass and heat relationships between products and reactants is called a thermochemical equation. 2 H 2 (g) + O 2 (g) ---- 2 H 2 O (l) ΔH = -571.6 kJ. The magnitude of ΔH is directly proportional to the amount of reactants or products.

10 examples of decomposition reaction

9 The reaction in which a chemical compound breaks down into two or more products is called a decomposition reaction. As stated earlier, such reactions usually require heat to occur. It is because when one chemical species decomposes into smaller parts, many bonds like covalent bonds are broken and to break those bonds, energy is required.

Flammability and thermal stability

A first general observation is that all mastics have a behaviour which qualitatively can be obtained by a simple superposition of the thermal decomposition curves of the two ingredients (asphalt binder and filler). Therefore, in the mastics ATH decomposes during phase I while MH decomposes during phase II and calcium carbonate during phase III.

As per initial reports, limestone was used in these walls, but the thermal conductivity examined was in the range of 0.84 to 0.88 W/m K which is quite low in comparison with the actual limestone thermal conductivity value of 1.3 W/m K. This shows that the wall materials are in a process of becoming porous and over time this will get worse.
