Utilisation of high volumes of limestone quarry wastes in concrete
In limestone quarries, considerable amounts of limestone powders are being produced as by-products of stone crushers.High amounts of powders are being collected and utilisation of this by-product is a big problem from the aspects of disposal, environmental pollution and health hazards. In conventional concrete, the introduction of Quarrying for limestone is an economic necessity that is not only hazardous to human but also one that invariably has deleterious effect on the environment.

Use of quarry waste in concrete and cementitious mortars
The use of waste quarry dust to partially replace river sand was investigated (Gopalakrishnan et al., 2020) by studying the effects on the properties of lightweight foam concrete at five contents, starting at a 10% replacement and up to 50% replacement at 10% increments, in mixtures with only cement included as binder.The use of quarry dust in high volume, in construction applications, through a technically and economically feasible technology, could lead to both economical and environmental benefits for the quarrying industry.

The limestone extraction process is a multi-step, labor-intensive undertaking. First, the raw materials (limestone) are extracted from the quarry by blasting and drilling. The stone is then loaded onto trucks for transport to processing facilities, which are crushed into smaller pieces.Limestone Extraction from Florida Quarries! Supply Chain

Recycling of quarry dust for supplementary cementitious materials
Therefore, the quarry industries are trying to find ways for reusing the waste. Similar to quartz dust, quarry dust is generally considered as inert material in the cement hydration [21]. As a result, it shows great potential to use quarry dust as an alternative SCMs in the cement production.Environmental Impact Assessment (EIA) is a prominent technology to assess the environmental changes in the open cast Limestone mining region. However, traditional EIA methods and Limestone deposit identification involves time consuming, cost effective and manpower requirements.
