The use of crushed limestone dust may affect the properties of concrete. As per Celik and Marar [2] the inherent property of concrete to flow known as workability decreases with the use of crushed limestone dust. This is due to the presence of finer particles whose specific surface area is high, which absorbs more water and leads to a reduction in slump value.

Calcined lime and hydrated limestone are reactive due to free CaO that reacts with water to produce Ca(OH) 2 improving soil's geotechnical properties. Where non-reactive limestone is used to enhance the properties of clayey soil [29], limestone has not been used in combination with cement. This leaves the effect of inert limestone on cement ...

To address dust pollution in a limestone mining area, we successfully prepared an efficient glycerol-microbial dust suppressant using Sporosarcina pasteurii XL-1 and glycerol via microbially induced carbonate precipitation. The results revealed that glycerol not only improved the wettability of the dust suppressant but also promoted bacterial growth.
