Experimental program Materials and mix proportions The cement used in experiments was ordinary Portland cement with grade P.O 42.5 came from Ningxiang cement Plant, and related parameters are shown in table 1.
These results demonstrate the value of admixture A additives for the durability of materials in aggressive environments.
For the materials and testing procedures used in this study, it was found that steam-cured concretes from OPC and admixture A mixes were more porous as indicated by the much higher sorptivity values compared to the 28-day standard-cured specimens.

Among various methods of powder synthesis, chemical methods are an important contribution of chemistry in materials science, because they allow manipulation of the matter in a molecular level.
Therefore, it has been even more important and necessary to have versatility in the project and in the synthesis of new materials, in order to those properties permit a better performance in their final applications.
