Inorganic Cementing Materials Used In Drymix Mortar


Inorganic Cementing Materials Used In Drymix Mortar

Inorganic cementing materials are an important component of drymix mortar, providing the necessary binding properties to hold the other components together. Here are some commonly used inorganic cementing materials in drymix mortar:

  1. Portland cement: Portland cement is the most commonly used cement in drymix mortar. It is a fine powder that is made by heating limestone and other materials to high temperatures in a kiln. When mixed with water, Portland cement forms a paste that hardens and binds the other components of the mortar together.
  2. Calcium aluminate cement: Calcium aluminate cement is a type of cement made from bauxite and limestone that is used in specialized drymix mortars, such as those used for refractory applications. It is known for its fast setting time and high strength.
  3. Slag cement: Slag cement is a byproduct of the steel industry and is a type of cement made by mixing ground granulated blast furnace slag with Portland cement. It is used in drymix mortar to reduce the amount of Portland cement needed and to improve the workability and durability of the mortar.
  4. Hydraulic lime: Hydraulic lime is a type of lime that sets and hardens when exposed to water. It is used in drymix mortar as a binder for restoration work and for masonry construction where a softer, more flexible mortar is needed.
  5. Gypsum plaster: Gypsum plaster is a type of plaster made from gypsum, a soft mineral that is commonly used in drymix mortar for interior wall and ceiling applications. It is mixed with water to form a paste that hardens quickly and provides a smooth surface.
  6. Quicklime: Quicklime is a highly reactive, caustic substance that is made by heating limestone to high temperatures. It is used in specialized drymix mortars, such as those used for historic preservation and restoration work.

Overall, the choice of inorganic cementing materials in drymix mortar depends on the specific application and desired properties of the final product. The right combination of cementing materials can provide the necessary strength, durability, and workability required for a wide range of construction applications.
