Use Of Calcium Carbonate In Building And Constructions

Calcium carbonate is critical to the construction industry, both as a building material in its own right (e.g. marble), and as an ingredient of cement. It contributes to the making of mortar used in bonding bricks, concrete blocks, stones, roofing shingles, rubber compounds, and tiles. Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper. Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water.

Calcium carbonate (CaCO3) is a widely used material in the building and construction industry due to its abundance, affordability, and versatile properties. Here are some key uses of calcium carbonate in building and construction:

1) Cement Production: Calcium carbonate is a primary ingredient in the manufacture of cement. It acts as a source of lime (CaO), which is essential in the chemical reaction that produces cement. When calcium carbonate is heated in a kiln, it decomposes to produce lime and carbon dioxide.

2) Concrete Production: As a component of cement, calcium carbonate indirectly contributes to the production of concrete. Concrete is a composite material made of cement, water, aggregates (such as sand and gravel), and often admixtures. The calcium carbonate in cement helps bind the aggregates together to form a solid and durable structure.

3) Lime Mortar: Historically, lime mortar was used extensively in masonry construction. Lime (obtained from calcium carbonate) mixed with sand and water creates a mortar that is flexible, breathable, and suitable for historic buildings.

4) Plaster and Plasterboard: Calcium carbonate is used as a filler and coating pigment in plaster and plasterboard products. It enhances the whiteness and opacity of these materials, improving their appearance and performance.

5) Paints and Coatings: In the construction industry, calcium carbonate is used as an extender in paints and coatings. It improves the paint's properties, such as durability, brightness, and consistency, while reducing costs.

Whitish deposits of calcium carbonate, CaCO3, frequently develop on Portland cement concrete and on masonry units, including brick and tile, which have been bonded with Portland cement. These surface deposits are termed efflorescence and are most frequently encountered in new or recent construction. While efflorescence is not normally damaging, except possibly to decorative coatings, it is aesthetically undesirable. The origin of efflorescence is explained and a physicochemical model is developed to explain and quantify the key features of its formation. Calculations and experiments highlight the important role of soluble alkalis in the formation of efflorescence. Mechanistic interpretations and calculations suggest ways in which efflorescence can be mitigated by interrupting one or more steps of the process in conjunction with improved materials selection.
