Concrete sealer. Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing. [1]
When atmospheric carbon dioxide (CO 2 ), or carbonate ions ( HCO− 3, CO2− 3 dissolved in water) diffuse into concrete from its external surface, they react with calcium hydroxide ( portlandite, Ca (OH)2) and the pH of the concrete pore water progressively decreases from 13.5 – 12.5 to 8.5 (pH of water in equilibrium with calcite ).
The environmental impact of concrete, its manufacture, and its applications, are complex, driven in part by direct impacts of construction and infrastructure, as well as by CO 2 emissions; between 4-8% of total global CO 2 emissions come from concrete. [1] Many depend on circumstances.
The alkali–silica reaction ( ASR ), also commonly known as concrete cancer, [3] is a deleterious internal swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous ( i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.
In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.
Stone sealer. Stone sealing is the application of a surface treatment to products constructed of natural stone to retard staining and corrosion. [1] All bulk natural stone is riddled with interconnected capillary channels that permit penetration by liquids and gases. This is true for igneous rock types such as granite and basalt, metamorphic ...
