What follows is a short presentation of some results of a research project on demolition, recycling and dismantling of reinforced concrete. This paper deals with some of the results obtained with the fragmentation of 30 types of 15 years old concrete, with separation of the reinforcement by means of explosives and with the recycling of the fragments as aggregates for new concrete.
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 annual …

Concrete is the most consumed material in the world, with 30 gigatons of annual demand (Monteiro et al., 2017).In Europe, concrete waste alone contributes about 30% of the total mass of solid waste (Böhmer et al., 2008).Made of sand and gravel bonded together by …
Plastic waste causes severe environmental impacts worldwide and threatens the lives of all creatures. In the medical field, most of the equipment, especially personal protective equipment (PPE), is made from single-use plastic. During COVID-19, the usage of PPE has increased, and is disposed of in landfills after being used once. Worldwide, millions of tons of …
Fundamentally, a material that constitutes at least two different materials is a composite. Bricks, concrete, wood, bone, and manufactured composites such as fiber-reinforced plastics (FRP) would be incorporated in this definition [1, 2].Nowadays, FRPs are applied for the fabrication of different structures, owing to high strength, high stiffness, and the combination of …
1 Introduction. Fiber-reinforced polymer (FRP) composites, comprised of a polymer matrix reinforced with fibers, have drawn significant interest in the last two decades as an alternative to traditional monolithic materials due to their higher specific strength and modulus, lightweight, adjustable deformation behavior, and good corrosion resistance.
The installation allowed sub-standard concrete and reinforced concrete products to be destructed, armature to be separated, and granulated concrete partially ready for recycling to be prepared. The electrode system that transmits impulses from the IVG through high-voltage electrodes to the destructible RCP is the actuator of the installation.
