Australians only wash glass sand. Recycled glass is produced by Australia's first recycling plant. This fixed plant uses detergent technology to convert waste glass sand, which is regarded as an unusable resource, into a clean glass sand, which is composed of different particle sizes and is free of odor and stubborn pollutants.
Foundry sand is usually recycled and reused in many production cycles. According to industry estimates, about 100 million tons of sand is used for production each year. Of that figure, only four to seven million tons are discarded, and even the sand is often recycled by other industries. Sand molding process and method

In the market, reclaimed sand with water absorption less than 5 is usually in good quality grade. 3.3. The proportion of hardened cement and sand in the recycled part. Generally speaking, crushed concrete fine aggregate mainly contains hardened cement and quartz sand
In today's society, the rapid growth of waste production, especially construction waste, has become one of the main problems in today's society. In the world, there are different reasons for the failure of reinforced concrete structures. These disruptions generate more and more waste value. In addition, there are several stone factories in each area, which produce a large number of building decoration stones...
Our study focused on the feasibility of using recycled concrete fine aggregate instead of sand to produce mortar, i.e. composite materials made of cement, fine aggregate, water and final admixtures and additives, especially those used as wall coatings and mixed immediately on site.
Recycled sand is produced from construction and demolition waste on ResearchGATE (a professional network of scientists). Only the port production base can bring the annual price...
Production of sand from construction and demolition waste the project is a demonstration of how to recover sand from construction waste and demolition debris. She showed how to solve a lot of problems by recycling the necessary sand from the rubble at a construction site. This will not only reduce the amount of waste produced in Sao Paulo from 500 to 1000

The purpose of this paper is to determine the maximum replacement amount of recycled sand to natural sand in the production of M-10 masonry mortar. For this purpose, volume tests were carried out on five replacement levels, namely 0, 25, 50, 75 and 100. Cement cemiibl 32.5 n is used as the mixture, and the volume ratio of cement and aggregate is 15.
Over the past two years, Niagara has developed an innovative idea for the use of recycled glass in biological retention rainwater systems. If successful, this will create a secondary market for recycled glass and provide an alternative source of sand composition in engineered biological soils.
