However, concrete can actually be recycled and reused. Here’s how the process works. First, broken or leftover concrete is collected from construction sites. This material is then crushed into small pieces, which are known as aggregate. The aggregate is then mixed with a binding agent and water to create new concrete.These machines typically employ hammer mills or cone crushers to crush the coal into smaller particles. This size reduction allows for coal-fired plants to generate electricity with increased efficiency and reduced emissions. In the construction industry, concrete crushers play a crucial role in recycling waste concrete into usable aggregate.The 10 Best Crusher Manufacturers & Brands in 2023

Abstract. Recycled concrete aggregates (RCAs) have low quality when compared with natural or conventional aggregates as the paste adhering to it is the key aspect that affects its functionality. Since the adhering cementitious paste weakens the adhesion between the aggregate and the binder, it becomes a decisive factor in the 6.1. Coarse recycled aggregates for concrete. Recycled aggregates are produced from processing construction and demolition waste. Construction and demolition waste is preliminarily sorted, in order to remove unintended deleterious materials (such as asbestos and gypsum-based materials), and recycled aggregates are then produced Recycled concrete for structural applications ScienceDirect

Increasing construction aggregate demand and demolition waste have led researchers to recycle concrete waste and produce recycled concrete aggregates (RCA), which can replace natural aggregates (NA) partially or fully (Xiao et al 2012, Arezoumandi et al 2015, Bhasya and Bharatkumar 2018, Hu and Kundu 2020, Dos Reis et al 2021).Over This study estimated the compressive strength of recycled concrete using six machine learning approaches, including GB, XGB, SVR, GB_PSO, XGB_PSO, and SVR_PSO.
