by Mechanized sand, commonly known as artificial sand, is a type of rock particle with a nominal particle size of less than 5mm that is formed by soil removal, mechanical crushing, and screening, but does not include soft or weathered particles.
In recent years, there has been a continuous shortage of sand for concrete, with prices constantly rising.
In some places, even with money, it is difficult to buy qualified river sand.
River sand and even desalinated sea sand have gradually become scarce resources.
Therefore, promoting the use of machine-made sand has become an inevitable choice.
In March 2020, the National Development and Reform Commission and 15 other departments issued the “Guiding Opinions on Promoting the Healthy and Orderly Development of the Sand and Gravel Industry”, proposing to promote the high-quality development of mechanism sand; Guangdong Province also released a specific implementation plan in May 2021, clarifying that the mainstream direction of construction sand in the future is machine-made sand.
The development of mechanism sand is flourishing.
However, there are various types of machine-made sand on the market at present, and many manufacturers lack professional technical personnel and knowledge, resulting in vastly different quality of machine-made sand.
