Current Applications of Recycled Aggregates from

A literature review comprising 163 publications published over a period of 26 years from 1992 to 2018 is presented in this paper. This review discusses the Brazil is one of the world’s major ornamental stone producers. As a consequence, ornamental stone wastes are generated on a large scale and are usually open air disposed. Thus, it is important to develop novel material reusing these accumulated wastes, aiming to minimize environmental impact.

Applied Sciences Free Full-Text A Novel Artificial Neural

Most regulations only allow the use of the coarse fraction of recycled concrete aggregate (RCA) for the manufacture of new concrete, although the heterogeneity of RCA makes it difficult to predict the compressive strength of concrete, which is an obstacle to the incorporation of RCA in concrete production. The compressive strength of The recycled aggregate is an alternative with great potential to replace the conventional concrete alongside with other benefits such as minimising the usage of natural resources in exploitation to produce new conventional concrete. Eventually, this will lead to reducing the construction waste, carbon footprints and energy consumption. This paper aims to study Infrastructures Free Full-Text Recycled Aggregates

The use of construction and demolition waste as a recycled

According to Muduli and Mukharjee (2019) a higher air content value was recorded for RCA than the normal aggregate concrete. However, the research of Falek et al. (2017) revealed that an inverse relationship exists between the density and the amount of RA in the concrete mixture. As the quantity of the fine recycled aggregate increases, then Attached, old mortar removal methods are evolving to improve recycled aggregate quality. Despite the improved quality of recycled aggregate, treatment of recycled aggregate at the required level cannot be obtained and predicted well. In the present study, an analytical approach was developed and proposed to use the Ball Mill Method smartly. Optimizing the Treatment of Recycled Aggregate (>4 mm), Artificial
