Ordinary terrazzo (also known as grinding stone) is a product made by mixing aggregates such as crushed stone, glass, quartz stone, etc. with cement binder to make concrete products, and then grinding and polishing the surface. Traditional terrazzo has a huge market in China due to its unique advantages such as low cost, the ability to mix colors and patterns freely, and convenient construction. As many as one billion square meters of terrazzo flooring have been used in various types of buildings in urban and rural areas across the country.
