Calcium chloride ( Cacl2 ):
An inorganic compound, (salt) with the chemical formula of CaCl₂. It has white color crystalline solid at normal room temperature, with highly soluble property in water, Acetone & Acetic acid. Calcium chloride has a melting point of 772 °C & the Boiling Point of 1,935 °C.
Sulfur trioxide ( SO₃ ):
A chemical compound, with a relatively narrow liquid range. In the gaseous form, this category has a significant pollutant, act as the primary agent in acid rain. With the melting point of 16.9 °C & Boiling point of 44.9 °C, It is prepared on an industrial scale as a precursor to sulfuric acid. sulfur trioxide is Colorless liquid & gas having a white crystalline solid formation which will fume in the air.
the most basic of the calcium aluminates is formulated as 3CaO·Al₂O₃ to highlight the proportions of the oxides from which it is made mostly related to the heat of hydration, It does not occur in nature but has an important role of mineral phase in Portland cement.
With the Melting point of 1,542 °C, it releases a large amount of heat during the first few days of hardening which generally results in early age cracking. Cements with the high content of C3A are not suitable for mass concreting and are better to be mixed with fly ash.
