外文摘要：Based on the investigation of the application of machine-made sand in Shaoxing, Zhejiang Province, this paper analyses the supply and demand of local machine-made sand, combined with the application of machine-made sand in highway engineering projects such as Hangzhou Shaoxing Taizhou expressway. It discusses the problems existing in the current machine-made sand industry, such as slow overall application, uneven quality and low application of high-grade concrete, and puts forward many measures to promote high-quality machine-made sand. In the application of high-grade concrete, it is suggested that the government should develop the machine-made sand market jointly with many departments, increase efforts to crack down on the inferior sand, cultivate the high-quality machine-made sand market, and improve the engineering quality of the machine-made sand concrete. ?
