Mortar and Cement

Calcium hydroxide is known as hydrated lime or slaked lime, and it is used extensively in some applications because it is less expensive than NaOH or KOH. It reacts with C02 to form CaC03, which binds particles of sand and gravel together in mortar and cement. 

Uses. For arresting decay and disintegration of stone for manufacture of weatherproof and acid-proof mortars and cement... 

The alkaline earth metal hydroxides M(OH)2 (M = Mg, Ca, Sr, or Ba) are also strong bases ( 100% dissociated), but they give lower OH- concentrations because they are less soluble. Their solubility at room temperature varies from 38 g/L for the relatively soluble Ba(OH)2 to 10-2 g/L for the relatively insoluble Mg(OH)2. Aqueous suspensions of Mg(OH)2, called milk of magnesia, are used as an antacid. The most common and least expensive alkaline earth hydroxide is Ca(OH)2, which is used in making mortars and cements. It is called slaked lime because it is made by treating lime (CaO) with water. Aqueous solutions of the slightly soluble Ca(OH)2 (solubility 1.3g/L) are known as limewater. 

Calcium oxide, CaO (lime), is used to make mortar and cement. 

The several manufacturers of chemical resistant mortars and cements publish extensive charts listing their products and various corrosive agents. Such charts indicate the degree of resistance of the cements and mortars. These manufacturers also publish details of corrosion resistant masonry construction. The technical representatives can be of help, however, the degree of expertise of these representatives varies widely from excellent to order taker so they are suspect until proven otherwise. 

Magnesite Refractories.—The mineral magnesite, MgCOa, is the source of bjusic refractories used as furnace linings for various metallurgical processes, in the form of bricks or in the crushed state as a mortar and cement for furnace bottoms. The most prominent uses of these materials are in the basic open-hearth furnace and electric-furnace linings. 

Use Weatherproof and acid-proof mortar and cements, refractory bricks, other molded objects, heat-resistant paints, chemical-resistant paints, protective coatings for industrial buildings and castings, lacquers, bonding agent, intermediate.

On the surface of concrete, finishing plaster or the other building materials the processes generated by the impact of gaseous air components or rain component occirr. Apart from the corrosion phenomena due to the acid rains, the carbonation of calcimn hydroxide influenced by CO2, is of highest importance. This process refers especially to concrete, mortar and cement plasters.
