As the properties of products are significantly affected by physicochemical specifications of limestone or dolomite the characterisation of those materials is important This study was initiated to analyse the chemical decrepitation and degradation properties of dolomite and limestone samples to determine their suitability as flux
Dolomite for Steel Industry In addition to being a raw material for the paint industry and iron manufacturing dolomite also plays a vital role in steel making Given its acidic nature the dolomite used in the steel industry must contain less than 1% of silica Here it finds use as a fluxing and refractory material
Dolomite rock also known as dolostone is primarily used in various construction and industrial applications due to its unique properties The primary uses for dolomite rock include Construction
In addition to utilising a waste by product of the shellfish industry and potentially improving the affordability of concrete production it is thought the use of crushed shell enhances surface roughness and provide chemical cues to induce settlement of mollusc larvae and so enhance bioreceptivity of biogenic species such as oysters
Application of Dolomite Minerals in Construction Ceramic and Glass Industry The most common use of the product is in the construction work as it can be easily crushed and sized for usage as a road base material an aggregate in concrete and asphalt railroad ballast rip rap or fill
