problems concerning premature sand clogging and failures with ASTM C-33 sand as the filter media, revisions were made to the Recommended Standards and Guidance (RS&G) for Intermittent Sand filters in 2000. The revised RS&G began to allow the use of a coarser sand media specification that is more clog-resistant than the ASTM C-33 sand specification.

Introduction Machine-made sand is different from the natural sand, it is made by making machines and other specific equipments. In recent years, sand and gravel market demand shows an increasing trend year by year. According to the data show that China's aggregate annual production reached 10 billion tons. Because of the influence of ...

Zhao, Y. Xu and C. Li: Study on workability of plastic fresh concrete with machine-made sand. Proceedings of the 2011 IEEE International Conference on Transportation and Mechanical & Electrical Engineering, December, 16-18, 2011, TMEE2011, p.2013-(2016). DOI: 10.1109/tmee.2011.6199611

The formation process of machine-made sand is mainly sand processed by crushers, sand making machines and other ancillary equipment; water-washed sand is raw sand for foundry that is washed and graded by natural silica sand; therefore, machine-made sand and water-washed sand are different. And machine-made sand can be used in many construction ...

specification. Shotcrete shall be uniform and dense, free from "drummy" areas that indicate laminations, voids, sand pockets, or disbonded material. 4.
