Quarry planning encompasses a comprehensive analysis of geological, environmental, and market factors to optimise resource utilisation and ensure sustainable development. In the UK, quarry planning must align with statutory requirements outlined by planning authorities and environmental agencies.
The research investigated the properties of black cotton soil when stabilized by lime, bagasse ash and combination of lime, ash and quarry dust. The experiment covered grading test, Plasticity index (Atterberg) and California bearing ratio (CBR). Key Words: Bagasse ash, lime, quarry dust, atterberg, CBR with cement, lime, bitumen and …

consisting of 30% waste plastic, 25% y ash, and 45% quarry dust was identied as highest compressive strength compared to the conventional one. Furthermore, a comprehensive probabilistic analysis was conducted, revealing that the most suitable probabilistic model aligns with the normal distribution.
The quarry is the result of many years of manual extraction, which produced underground spaces supported by imposing irregular pillars. A great lake inside the quarry makes this extraordinary hypogean architecture very suggestive (Fig. 7). The lake, produced by the penetration of aquifers that extends for much of the surface of the …
The present paper proposes a multicriteria approach that is able to support decision makers in the choice of the best solution for the reuse of an abandoned open …

1. Introduction. Concrete is a sustainable and versatile construction material which can produce structures that last for thousands of years. Due to the many areas of application, concrete is the second most consumed material on Earth, only after water, with a global production of around 4.1 billion tons of cement in 2021 (Statista, 2023), and an …
The study was carried out on M20, M30, and M40 grade concrete with 0.5 water cement ratio. Waste plastic was mixed as 2, 4, 6, and 8% along with quarry dust to make full combinations. Regression analysis is carried out to co-relate compressive strength for 7, 14, 28, 90 days represented in fig.1 to 4.

Through survey and analysis of participants' design evaluations, this study provides strategic direction to the design and marketing fields in their development of new global products. Taiwan's Future design styles and the development of her cultural and creative industries can derive greater application and value from this.
In this study, we selected a degraded slope from a limestone quarry located in Almería province (SE Spain) and modeled how active restoration of the biocrust …
Rock slope geometry and discontinuity properties are among the most important factors in realistic rock slope analysis yet they are often oversimplified in numerical simulations. This is primarily due to the difficulties in obtaining accurate structural and geometrical data as well as the stochastic representation of discontinuities. Recent …

The majority of the wet digestion methods, followed in geochemical analysis, use acids such as HCl, HNO 3, HClO 4, H 2 SO 4 and HF, or a combination of them. The use of HF becomes inevitable in most sample decompositions because of its ability to dissolve silica and other silicates by the following reaction: SiO 2 + 6HF → H 2 SiF 6 + …
The Lafarge-M'sila group's cement plant (Algeria) is supplied by the Chouf Amar limestone quarry, which allows great quarrying at the national level with annual productions of 4.2 mt / year, since several sliding in previous years have disrupted the exploitation and production of the quarry, and in the strategy of the Lafarge group increased its production up to …
