However, since some substitutes use CO 2 released by thermal power plants to make cement, there is a distinct possibility of cement plants making new types of cement by using CO 2 from kiln exhaust gases and from captive power plants. 3.5. Therefore at this stage to design green cement plants the cement industry will have to depend on 1.
Composition of Ordinary Cement The ordinary cement contains two basic ingredients, namely, argillaceous and calcareous. In argillaceous materials, the clay predominates and in calcareous materials, the calcium carbonate predominates. A typical chemical analysis of good ordinary cement along with the desired range is given in table 6-1.
Mar 29, 2020 Concrete defines as a composition of construction material cement, fine aggregate i.e. sand, coarse aggregate, and water which harden with time. Generally, if the concrete is used with steel than it is called as a Reinforced Cement Concrete.
