Recrystallization is the process by which new dislocation-free grains are formed within the high-energy deformed structure by the migration of high-angle grain boundaries [1].
Chemistry of precipitates was studied by Energy Dispersive X-ray Spectrometry (EDS) using carbon extraction replicas.

The adsorption of surfactant at solid-liquid interface is strongly influenced by a number of factors which are the nature of the structural group on the solid surface (adsorbent), the molecular structure of the surfactant (adsorbate) and the environment of the aqueous phase [8].

Recognize the ecological risk of resource-based cities
Ecosystems and their ecological risk is the risk of exposure to components, means a species, ecosystem or the normal function of the landscape affected by stress outside, thus reducing the current and future certain elements within the system or their own health, productivity, genetic structure, economic value and aesthetic value of the potential[3].

These products and the structure of autoclaved fiber cement are more susceptible to chemically corrosive substances such as CO2. [1] The following table shows a comparison of the chemical composition of autoclaved and air-cured fiber cement.
Likewise, it was proven that the use of fiber cement did not significantly affect the chemistry and morphology of the resulting clinker minerals.
