Standard For Railway Sand

Last Update:2020-05-10 19:54:35

What are the requirements / standards for railway sand? There are different requirements for grain shape, stone powder content and grain graded sand of railway sand. In the construction of railway engineering, it is mainly used in the masonry of permeable filler, subgrade, bridge and culvert, tunnel, house and other buildings and structures. Therefore, the amount of sand is quite large. However, when the problems of large demand, less resources and high quality requirements appear, it becomes an important issue to seek alternative solutions to solve the problem of sand use. In the railway survey in mountainous areas, there is often a lack of natural sand but abundant stone resources. In this case, it can be considered to replace natural sand with machine-made sand made of hard rock by blasting and mechanical rolling, which can be used in concrete masonry.

What are the requirements / standards for railway sand? The machine-made sand is made of limestone, dolomite, granite, basalt and other hard rocks by blasting and mechanical rolling. Three important technical indexes of machine-made sand, such as particle shape, stone powder content and particle grading, affect the workability, strength, dry shrinkage resistance and wear resistance of concrete.
