A slurry is, in general, a thick suspension of solids in a liquid and may be:

• A mixture of water and cement to form concrete.
• A mixture of water, gelling agent, and oxidizers used as an explosive.
• A mixture of water and Bentonite used to make slurry walls.
• A mixture of wood pulp and water used to make paper.
• A mixture of water and animal waste used as fertilizer.
• Meat slurry, a food product.
• An abrasive substance used in chemical-mechanical polishing, a semiconductor manufacturing process.
• A mixture of ice crystals, water and freezing point depressant, called slurry ice.
• A wet-process cement rawmix.
• A mixture of water, ceramic powder and various additives (e.g., dispersant) used in the processing of ceramics.
• A mixture of water and a starch (normally corn starch) used to thicken liquids to make a culinary sauce; usually for a clear sauce, as the product will be translucent. It is comparable to and often the same as a gravy.r a clear sauce, as the product will be translucent. It is comparable to and often the same as a gravy.

In some industries slurry is man made for disposal as a waste product of a particular dusty material for Transportation to another location by pumping. Slurry is automatically generated in the process in industries for further processing to obtain the intermediate or end product. In civil construction works slurry can be muddy water to be pumped out from trenches. In civil maintenance works on sewage disposal slurry can be from the sewage tanks. Slurry can be a special mixture used for aerial fire fighting.

In farming - perhaps the best known use - farm slurry is a mixture composed chiefly of water and animal sewage. It has a distinct odour, noticeable when the substance is carried in tankers, or spread over fields. Misapplication of farm slurry can lead to environmentally damaging emissions of ammonia and other chemicals. Slurry can be a liquid mixture (especially involving water) composed of a mixture of various insoluble matter, such as mud or plaster of paris etc. in construction sites. A special kind of slurry consisting of approximately 1% pulp (wood fiber) and 99% water, used to make paper, is called stock in the papermaking industry. In wildland firefighting, slurry is a term used for the fire retardant dropped on a forest fire from an aircraft. "Slurry bomber" is a colloquial term for those aircraft. See aerial firefighting. In cooking, particularly in restaurant kitchens, slurry refers to a mixture of a thickening agent (often cornstarch) and water, as a means of dispersing the thickener into hot sauces and soups near the end of the cooking process without forming lumps. Slurry can also refer to the mixture of coffee grounds and water in some kinds of brewing processes, such as a french press.
