The challenge of disposing of large quantities of waste from quarries is a reality: in Ticino, they can even reach 40% of the total production. To counteract this problem, the Swiss Federal Institute of Technology Zurich (ETH) and the SUPSI Institute of Earth Sciences have developed a 3D printer to produce customizable architectural …
During two-field investigations, in the years of 2016 and 2018, data were collected in 22 well-known granite, limestone, marble, and slate quarries around Portugal for discontinuity mapping using a low cost commercial drone, alongside the conventional field work methods which were mentioned in Sousa et al. ( 2017 ).
From the inception of the mining and manufacturing of these dimensional stone, no proper care were taken to control, reduce or recycle the waste produced, leading to accumulation of these...
thus, economically valuable. In marble quarries, stones are cut as blocks through different methods. During the cutting process, 20-30% of a marble block becomes waste marble powder. Marble powder may be a waste generated in considerable amounts within the world. Marble waste results in a significant environmental problem further.
A study by Omar et al. (2012) that investigated the use of limestone waster to replace fine aggregate used in concrete utilized waste marble powder as an additive. Furthermore, 5%, 10%, and 15% waste marble powder was added to concrete mixtures prepared by replacing sand with limestone waste at rates of 25%, 50%, and 75%.
Currently, the company operates four quarries in South Dakota, one in Minnesota and is in the process of opening three sites in Wyoming for Red sandstone, Teton Taupe and Casper White. Alabama White marble's comeback
This paper reports the experimental study undertaken to investigate the influence of partial replacement of sand with limestone waste (LSW), with marble powder (M.P) as an additive on the concrete properties. The replacement proportion of sand with limestone waste, 25%, 50%, and 75% were practiced in the concrete mixes except in …
Waste generated at quarries and fabrication plants is quite similar. Most commonly, scrap stone must be mitigated and managed, …
Limestone is the primary rock quarried, followed by marble and granite. Crushed stone is quarried from 17 locations across the state. Several former dimension stone quarries are now used for ground product, …
Marble wastes in the quarry environment are in the form of slurry/powder and stones of irregular shape and size, which are dumped in open lands and along roads, which create a lot of environmental and health problems, as shown in Figure 1 [ 10, 11, 12, 13 ].
Marble wastes are generated by quarries (marble quarry waste-MQW) and processing plants (marble cutting waste-MCW). The proportion of marble discharged as waste during block production at the quarries is equal to …

The availability of a huge stockpile of cement grade limestone waste accumulated from 30 years of marble quarrying operations and news related to cement shortage in 2007 prompted MTSB to...
Lee County residents have protested against three quarries in the previous years. Shelby County residents have fought two quarry proposals, and Limestone residents have battled two. The Morgan County community has tried unsuccessfully to get the County Commission to prevent a quarry from reopening at Massey.
The effects of limestone waste as fine aggregate on several fresh and hardened properties of the concrete was investigated. The investigation included testing of compressive strength, indirect tensile strength, flexural strength, modulus of elasticity and permeability. It was found that Using Lime stone waste up to 50%
Fig. 2 Waste Generation during the Marble Production 3.1 Types of Marble Waste There are two types of marble waste: (i) Quarry waste This waste includes blocks of various sizes and shapes, undesirable trimming and shaping of mined out blocks before dispatch to processing units. There are two types of Quarry Waste as follows: a) Direct …
Wastes from this sector can be divided into two categories: block marble quarry wastes and marble processing wastes (Liguori et …

The water content variation (Δwcomp) obtained during the compaction in the field varied by − 1.0% for the soil–crushed rock mixture, − 2.0% for the quarry waste, − 6.0% for the fine soil, − 7.0% for the mixture of soil and lime, and − …
Cement plants, which require a massive quantity of CaCO 3, and consume a great deal of limestone, can use over 1000 tons of marble waste in a day. The most important parameter herein is the shipment cost to transport marble waste from quarries or plants to locations where it is to be reused.
A quarry is an open-pit mining process designed specifically for the removal of large deposits of rock. Quarries can be found all over the world and most are located where a particular type of rock - such as granite, marble, limestone, slate, or gypsum - occurs near the earth's surface.
To provide a comprehensive outline of marble's use as coarse aggregate in concrete production, this study adopted utilizing waste coarse marble aggregate …
