Limestone calcined clay cement (LC 3) is a promising alternative to OPC, offering reduced CO 2 emissions while maintaining comparable mechanical performance. LC 3 technology replaces up to 50% of the clinker in OPC with limestone and calcined clay [3], significantly lowering CO 2 emissions. For example, at a 50% clinker substitution level, LC 3 can reduce …
drainage originating from the coal and ore mining processes in general and open-pit mining in particular are well documented in the literature (Cherry et al. 2001; Skousen et al. 2002). Even though the environmental impacts of ore and coal mining have been adequately investigated, the impact of limestone rock mining has not been well studied.
Limestone comes in many different varieties. Chalk is a very fine grained, porous marine limestone composed almost entirely of microscopic fossils. Travertine is a freshwater sedimentary limestone that has very thin, crenu-lated layers and is commonly formed at springs. Marble is a carbonate rock, usually a marine limestone, that has been

The study area is situated south east of Kota district in Rajasthan which is undergoing massive mining activity of limestone popularly known as Kota Stone mining.
This study investigates the roof stability of underground limestone mining in the presence of stratified joints during the excavation process. An analytical solution is derived to predict the stresses and deformation of underground tunnel structures, with the structure simplified as a double-hinge arch. The accuracy of the analytical model is validated through …

In this study, we investigated the impact of quarrying as an environmental ethical crisis. The need for the study arose when we realised the deteriorating effect of the quality of life in our community, which is located next to a limestone quarry. To obtain a deeper understanding of the adverse impact on the environment and the quality of life of the people living in the …
Effect inhaling of limestone dust exposure on increased level of IL-8 serum and pulmonary function decline to workers of limestone mining industry. Int. Refereed J. Eng. Sci. 3, 66–72.
Limestone has always been widely used in various sectors, thus having significant economic and environmental impacts. The quarrying process is, on the one hand, essential, but on the other, …
Mining is a global phenomenon and an age-old major economic activity to extract minerals, stone, coal, or oil and gas in many countries of the world including India (Ranjan et al. 2023; Dubey and Dubey 2020).These natural earth's mineral resources are nonrenewable resources and are mainly used by human being for building materials, sustenance of life, …
processes in general and open-pit mining in particular are well documented in the literature ((Cherry et al., 2001; Skousen et al., 2002). Even though the environmental impacts of ore and coal mining have been adequately investigated, the impact of …
BACKGROUND: Limestone dust is produced by limestone mining activities, one of them is PM2.5. Exposure of PM2.5 can cause lung function impairment.
Three keywords (i.e., industry, society, and limestone mining) are important to describe this chapter in continuation of the preceding chapter, which explained the mining or excavation process. ... these standards are meant to protect human health from adverse effects and to ensure well-being of the common workforce engaged in limestone mining ...
