In the sand washing and aggregate washing process, wastewater generated by the quarrying industry will cause serious pollution to the environment. Sand washing equipment with a water recycling system can reuse 90% of aggregate washing water it is becoming more and more important for sand and gravel plants.
Compared with traditional aggregate recycling methods, microwave heating-assisted concrete aggregate recycling was proposed as a new green technology. The secondary environmental pollution and the degree of mechanical damage caused by microwave assisted concrete recycling are low [ 10, 11 ].
This means that recycling waste into coarse aggregate would contribute significantly to reduction of the waste. This resulted in studies on SCC with RCA (Recycled Coarse Aggregate) – the combination of Recycled Aggregate Concrete (RAC) with its ability to self-consolidate ( Fig. 1a ).
A comparative study of ensemble machine learning models for compressive strength prediction in recycled aggregate concrete and parametric analysis. Multiscale and Multidiscip.
Recycled aggregate concrete (RAC) not only alleviates the shortage of natural aggregates but also promotes the recycling of construction and demolition waste, contributing to sustainable development. Traditional empirical and statistical formulas have limited applicability and perform poorly when dealing with complex relationships.
Currently, a number of disadvantages hampers the use of recycled concrete aggregates (RCA). The current review proves that concretes made with complete replacement of natural aggregate with …

Jones Corporation is preparing an aggregate production plan for washing machines for the next four bany will have 1,000 quarters. The company's expected quarterly (4) demand is 20,000 washers.
OPES MRF 2013 Ltd. was established in 2013 to support the recycling industry in the UK by dealing with the residues that arise from primary sorting processes at our customers' sites.
After demolition of old roads and buildings, the removed concrete is often considered worthless and disposed of as demolition waste. By collecting the used concrete and breaking it up, recycled concrete aggregate (RCA) is created (Fig. 1 ). This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is …
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 …

We are committed to removing waste material from the environment by providing a waste disposal and recycling solution for construction companies, tier one contractors, civil engineers and local authorities.
Unfortunately, most of the research focused on using recycled concrete aggregate (RCA) as a base material to the pavement. But in other parts of the world, many recognize RCA as a valuable aggregate source when properly intregated into the mix design process. For example, Japan has used RCA for more than 20 years in structural …

A recycling plant is quite similar to the plant producing crushed natural aggregate. The recycling plant incorporates various types of crushers, screens, transfer equipment and devices for removal of foreign materials. A number of different processes are possible for the crushing and sieving of construction and demolition waste.
The construction industry has shown great gains in the recycling of industrial by-products and waste, including waste glass. Recycling of this waste by converting it to aggregate not only saves landfill space but also reduces the demand for extraction of natural raw material for construction activity (Rakshvir and Barai, 2006).
