- Efflorescence Found on Your Concrete Foundation Walls. Efflorescence is a problem that can be easily solved. If your home has efflorescence, you can detect this by looking at the concrete in the foundation or crawl space of your home.

White Residue on Grout When there is a whitish mineral residue on the grout, commonly this is caused by efflorescence. Similar to the white powder left in a drinking glass when a glass of water is left to evaporate, efflorescence is caused by minerals that are soluble in water being dissolved and transported to the surface of the grout as the water evaporates.

- The technical name for this white powder is Efflorescence (from the French, meaning to flower out). It is an accumulation of minerals and salts on masonry surfaces, such as brick, cement, and sometimes stone. Building inspectors and home owners should know how to prevent and remove this unsightly residue.

Top 30 Doctor insights on: What Is Tibiotalar Joint Effusion Effusion is the medical term for fluid. Not unusual to have some fluid anytime there is inflammation. But remember, inflammation can be from many different things. Arthritis, gout , infection (many more ). Up to the doctor, to evaluate the knee and determine why there is fluid. Best wishes.

Definitions &Translations fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation it is a form of luminescence in most cases the emitted light has a longer wavelength and therefore lower energy than the absorbed radiation

Efflorescence In what has been described as primary efflorescence, the water is the invader and the salt was already present internally. Some people describe a reverse process, where the salt is originally present externally and is then carried inside in solution, as secondary efflorescence..

Contractor's Guide to Efflorescence Efflorescence is a fact of life with most concrete. We are hearing more about efflorescence related issues because of the popularity of stained floors. As the trend to have exposed concrete floors grows, the industry is struggling with the problem of unsightly efflorescence, especially when it is trapped under a film forming sealer.

luminescence The emission of light as a result of the excitation of atoms by a source of energy other than heat. Bioluminescence, fluorescence, and phosphorescence are examples of luminescence that can be produced by biological or chemical processes. 2. The light produced in this way.

Effluent Effluent, in engineering, is the stream exiting a chemical reactor. Effluent is defined by the United States Environmental Protection Agency as  wastewater-treated or untreated-that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters .

Efflorescence Removal. 1  Pressurized water can sometimes be used to remove or dissolve efflorescence. 2  An acid, such as diluted muriatic acid, can be used to dissolve efflorescence. 3  A strong brush can be used to simply scrub the efflorescence off.

- 1 Answer from this member: Masonry and concrete deterioration is usually in the form of spalling. This is crumbling or flaking of the surface, usually because of efflorescence, freeze/thaw action, or water or mechanical impact, such as sandblasting or high pressure water washing.Water plays a large role in efflorescence and freeze/thaw damage.hile the mechanical action of water passing over masonry can deteriorate the masonry surface, the most severe deterioration is often associated with freeze/thaw cycles. Whether the water is from rain or snow on the surface or dampness from below or behind, water may accumulate near the surface of the masonry.

- The alkali sulfates in the wall are dissolved by water into a solution which then moves through the natural pores in the masonry. The solution migrates to the surface of the wall where the water evaporates, depositing the salts on the wall and generating the white powdery scum we know as efflorescence.Figure 1.e know that efflorescence is a fine, white, powdery deposit of water-soluble salts left on the surface of masonry as the water evaporates. These efflorescent salt deposits tend to appear at the worst times, usually about a month after the building is constructed, and sometimes as long as a year after completion.

fluorescence Fluorescence is generally defined as a luminescence emission that is caused by the flow of some form of energy into the emitting body, this emission ceasing abruptly when the exciting energy is shut off.

Effusion Definition, Types, Causes, Symptoms, Treatment Effusion Definition. Effusion is the term for accumulation of fluid in a body cavity particularly within the cranial cavity, in the middle ear, around the lungs, around the heart, in the abdomen (peritoneal cavity) and in the joint spaces. It is also referred to as fluid retention or water retention because most of the fluid is composed of water.

luminescence Various types of luminescence are often distinguished according to the source of the energy which excites the emission. When the light energy emitted results from a chemical reaction, such as in the slow oxidation of phosphorus at ordinary temperatures, the emission is called chemiluminescence.

- LUMINESCENCE is the emission of light from a substance bombarded by radiation. There are. two types; fluorescence and phosphorescence. Fluorescence means that luminescence is excited only during the period of. irradiation and will terminate at completion of the X-ray exposure.

- Pleural effusion, also called “water on the lung,” is an excessive buildup of fluid between your lungs and chest cavity. There’s always a small amount of liquid inside your lungs. This fluid works to coat the membranes (pleura) that line the outside of your lungs and lubricate the chest cavity to aid in breathing.

Joint effusion A joint effusion is the presence of increased intra-articular fluid. It may affect any joint. Commonly it involves the knee.
