Can machine-made sand and gravel aggregate replace cement concrete in highway engineering?
In infrastructure construction, natural sand is in short supply, making machine-made sand a substitute. Sand and gravel aggregates play an important role. In the process of preparing sand and gravel aggregates, the quality should be controlled and the cost should be reduced. To prepare sand and gravel aggregates, mine crushing and sand-making equipment must be used.
Large stones or rocks are crushed. There are many finished sand and gravel produced by the sand making machine, which can be completely comparable to natural sand, with reliable quality and strong fusion.
In the preparation process of sand and gravel aggregate, the large stones are continuously and uniformly transported to the jaw crusher by the vibrating feeder for a first-stage crushing operation. In order to crush large stones to the specified particle size, it often needs to be crushed several times to complete. Therefore, the aggregate crushing process is usually divided into jaw crushing for coarse crushing, impact crushing for secondary crushing, and sand making machine for fine crushing. The entire production line is reasonably configured, the finished product has good grain shape, strong plasticity, and a wide range of applications.
Advantages of machine-made sand: 1. Quality advantage. The fixed, stable and mechanized production method of the material source ensures that the quality of the finished machine-made sand is stable, adjustable and controllable. 2. Quality advantage. It has high surface hydrophilicity, complete gradation, and a variety of mineral components to choose from. The particle gradation is stable, and the discharge particle size is controllable. 3. Resource advantage. Various waste resources can be used to properly sort and process tailings, and many tailings can be made of artificial sand and gravel by using artificial sand equipment.
On the whole, it is possible to use machine-made sand and gravel aggregates for basic construction.
