AbstractThe present study discusses the possibility of preparing a type of acids- resistant binder to inorganic acids from materials available in Northern Iraq, to be used in the treatment of cracks that occur in the vats or containers of acid treatment, and may also be considered as a kind of acidic mixture, or paste, that bind types of acids resistant-brick as cementing material.
This work has been focused on the available raw materials such as white Quartzite rock found in appropriate amounts in various parts of Iraq besides to the use of Sodium Silicate (Water Glass) manufactured at Ramadi Glass Factory.
The current research comprises several stages in order to identify the most appropriate conditions for the production of this type of substance (acid proof cement), where the practical side deals with the preparation of raw materials used in the manufacture of this kind of substances.
We selected Quartzite rock to prepare filling materials (fillers), of sizes ranging from (50-300) micron after crushing, grinding, milling and size classification, as well as preparation of samples of cement consisting of different percentages of constituents, and study the impact of the degree of concentration of different acids, the sinking time, and the temperature on the overall qualities of samples prepared with a view to the most appropriate mixtures approved for this purpose.
It was concluded that the most appropriate amounts of the approved mixtures that were components of the solid / liquid ratio (2: 1) and as follows:
• Sodium Silicate (Water Glass): 22 -25 part.
• Silicate powder (Quartzite): 40 -45 part.
• Na-Fluro Silicate) Na2SiF6): 4-7 part.
