Study on Solid Waste Mechanized Sand of Its Concrete Properties
Under the background that large-scale infrastructure construction in our country needs huge amounts of sand aggregate,the state encourages the use of production mechanism sand such as tunnel slag,stone waste and so on.Using waste rock to process sand and gravel aggregate,short-term production and mobile crushing processing are more suitable for each storage point of waste rock,but such production process may affect the product quality of sand and gravel aggregate.In this paper,the quality and concrete performance of manufactured stone solid waste sand produced by mobile crushing equipment are tested and studied.The results show that manufactured stone solid waste sand meets the standard requirements and can be used as coarse aggregate for concrete.The concrete prepared by manufactured stone solid waste sand shows good compressive strength,but the workability,shrinkage and crack resistance are not significantly reduced,so it is feasible.
