| Abstract: | This paper mainly introduces the practical application of the machine-made sand in the Nanyu expressway. On the basis of this, it studies and analyzes the distinction of the machine-made sand and the natural sand, as well as the working principles of the concrete of machine-made sand and machine-made sand as fine aggregate of concrete, then the construction technology demands can be satisfied. The result shows that using machine-made sand in the expressway project is feasible. |
