“…According to the British Geological Survey (2020), every ton of recycled glass saves 250 kg of CO 2 during manufacturing, as well as 1.2 tons of raw material. Foundry sand can be reclaimed and reused (with the addition of some fresh sand) or can be used in asphalt or cement (BGS, 2020;Balbay, 2019;Borek et al, 2020).…”

An overview of the production and usage of quartz sand as a special sort of sand for civil engineering is presented – from the formation of sand deposits, through mining and processing methods, to its final use, with an emphasis on its use in civil engineering, i.e. in water filtration. Quartz is found in sedimentary, metamorphic, and igneous rocks. During sand formation in the fluvial environment, quartz grains are highly resistant to weathering and mechanical wear, and can be transported a long way without changes to size and form. Therefore, quartz is the main constituent of most natural sands. Quartz and quartz sand are ubiquitous raw materials used in a wide range of products in civil engineering due to their chemical inertia and high temperature resistance. An example of a quartz sand deposit and processing plant in Slovenia is presented as a practical case study on quartz sand application. The described applications using quartz sand are the best available technologies in sanitary and hydraulic engineering to be used for a move towards a circular economy, smart houses, and smart cities.

“…For this reason, the use of solid waste material or industrial byproducts as a partial cement replacement (supplementary cementitious material) in concrete is a viable strategy for reducing the use of Portland cement and for, therefore, reducing the environmental and energy impacts of concrete production [ 5 , 6 ].…”

“…At the end of the 1990s, several research works began to study the possibility of incorporating glass powder (GP) into the concrete composition as a substitute for part of the fine aggregate [ 6 , 19 ], as a substitute for cement [ 15 , 20 ], or as simply a part of it [ 21 ]. These studies aimed to verify how the incorporation of this recycled material would affect the properties of concrete, and different experiments on mortars commenced.…”

Characterization of Glass Powder from Glass Recycling Process Waste and Preliminary Testing

This work studies the possibility of incorporating different proportions of glass powder from the waste glass (rejected material called fine cullet) produced during the glass recycling process into the manufacturing of mortar and concrete. For this purpose, the material is characterized by its chemical composition and pozzolanic activity, and the shape and size of its particles are studied. It is then incorporated as a substitute for cement into the manufacturing of mortar and concrete at 25% and 40% of cement weight, and its effect on setting times, consistency, and mechanical strength is analyzed. Its behavior as a slow pozzolan is verified, and the possibility of incorporating it into concrete is ratified by reducing its cement content and making it a more sustainable material.

“…The granular nature of sand, its recycling capability combined with its complex interaction dynamics creates unique physical capabilities. The mixture of sand with other construction materials for example, creates important characteristics suitable for several mechanical and construction applications [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. This phenomenon has been studied here as an alternative to achieve the goal of bullet fragmentation.…”

Simulation of Bullet Fragmentation and Penetration in Granular Media

et al. 2020

The aim of this work is to simulate the fragmentation of bullets impacted through granular media, in this case, sand. In order to validate the simulation, a group of experiments were conducted with the sand contained in two different box prototypes. The walls of the first box were constructed with fiberglass and the second with plywood. The prototypes were subjected to the impact force of bullets fired 15 m away from the box. After the shots, X-ray photographs were taken to observe the penetration depth. Transient numerical analyses were conducted to simulate these physical phenomena by using the smooth particle hydrodynamics (SPH) module of ANSYS® 2019 AUTODYN software. Advantageously, this module considers the granular media as a group of uniform particles capable of transferring kinetic energy during the elastic collision component of an impact. The experimental results demonstrated a reduction in the maximum bullet kinetic energy of 2750 J to 100 J in 0.8 ms. The numerical results compared with the X-ray photographs showed similar results demonstrating the capability of sand to dissipate kinetic energy and the fragmentation of the bullet caused at the moment of impact.
