Soda lime is a mixture of NaOH & Ca(OH) 2 chemicals, used in granular form in closed breathing environments, such as general anaesthesia, submarines, rebreathers and recompression chambers, to remove carbon dioxide from breathing gases to prevent CO 2 retention and carbon dioxide poisoning. Free lime absorbs carbon dioxide in the setting process of carbonation. from a substance by the action of a liquid passing through the substance. See our Privacy Policy and User Agreement for details. Lime (d) Zinc is more reactive than hydrogen and it will displace hydrogen ion. The fat lime shrinks to a great extent and hence it requires about 2 to 3 times its volume of sand. Hydrated lime, fat lime and quick lime are the main types of lime in which hydrated lime are widely used in making construction. Good source of antioxidants. The essential properties of bricks may be conveniently discussed under the following four headings: physical, mechanical, thermal and durability properties.

But there are properties or characteristics of aggregate which influence the properties of resulting concrete mix. *)Soda-lime glass, also called soda-lime-silica glass, is the most prevalent type of glass, used for windowpanes, an d glass containers (bottles and jars) for beverages, food, and some commodity items. Fat limes or quick lime; Does not set under water, can be entirely dissolved by water, doubles its amount when slaked. The tensile strength varies from 40-150 psi. Physical (non-mechanical) properties 3. 5. It is not very soluble in water and its solubility reduces with an increase in temperature. registered in England (Company No 02017289) with its registered office at 26 Red Lion This mortar is unsuitable for water-logged areas or in damp situations.
