The Pros and Cons of Manufactured Sand

Rocks or quarry stones are blasted and subjected to a series of crushing cycles to reduce the particles to the size of naturally occurring sand. The produced sand is then sieved and washed to remove fine particles and impurities, and tested for various quality aspects before it is deemed fit as a construction aggregate. The si…

Sand Rock

Sand Rock was largely an unincorporated farming community for most of its existence. The first settlers, including members of the Brindley family, arrived in the 1830s. The first church was founded in the 1840s, as was a log-cabin school on the farm of H. S. Stowe. A post office was established in 1855 and operated until 1903.

Manufactured Sand

Fine sand: The fineness modulus is 2.2-1.6, and the average particle size is 0.35-0.25mm. Extra fine sand: The fineness modulus is 1.5-0.7, and the average particle size is below 0.25mm. Natural sand: Rock particles with a particle size below 5mm, formed by natural conditions (mainly rock weathering), are called natural sand.

Manufacturing Sand | Agg-Net

Manufactured sand ranges from unprocessed quarry dust to carefully processed fine aggregate specifically designed for use in concrete. It may be gritty, flaky and full of filler or well shaped and graded, assisted, perhaps, by the nature of the parent rock, to produce well proportioned particles in the right size range.

Manufactured Sand
