Exposure to limestone dust may cause irritation to the moist mucous membranes of the nose, throat, and upper respiratory system. It may also leave unpleasant deposits in the nose. Effects Resulting from Ingestion: Although small quantities of dust are not known to be harmful, ill effects are possible if larger quantities are consumed.
Inhaling marble dust causes toxic effects on the respiratory system. Workers and residents living in areas adjacent to stone quarries are prone to a disease called silicosis, whereby inhaled marble dust damages the cells of the respiratory system. Symptoms include a chronic cough and shortness of breath.
Limestone mines use two types of blasting. Small explosive charges set along drilled lines free blocks of stone to be removed for construction. Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust.
Heating limestone produces a chemical substance used in agriculture called pulverized lime, or calcium oxide. Generally, 2 mg of calcium oxide is considered safe for food use; however, concentrations of 25 mg can produce serious side effects including lung inflammation, according to a 2007 report by the Occupational Safety and Health Administration, or OSHA2.
Limestone, dolomite, and marble - the carbonate rocks - are the principal karst-forming rocks. Karst is a type of topography that is formed on limestone, gypsum, and other rocks by dissolution that is characterized by sinkholes, caves, and underground drainage regions. Karst areas constitute about 10 percent of the land surface of the world (fi g.

• Limestone powder can be blended and interground with Portland cement or it can be added as an aggregate to the concrete mix • Limestone blended cements (Type IL) are classified through ASTM C595. ASTM C595 was recently modified to allow for 15% of cement clinker to be replaced with ground limestone by mass
This study explored the effect of adding 10% of finely ground limestone dust to alkaline hybrid cements. A series of binders was prepared with 20–30% OPC (CEM I 52.5R) and fly ash in the presence or absence of a chemical activator (5% Na 2 SO 4).The rate of heat release was determined by isothermal conduction calorimetry.

Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO 3, the primary constituent of limestone) to form water, carbon dioxide, and calcium salts. The following depicts ...
