Our Tile and Bedding Sand (also known as Coarse Sand C38) is subrounded, clean, silica river sand that is graded to the ideal particle size greater than 0.6mm. It is our more popular sand used by commercial tilers for making site mixed screed as the shape and size ensures easy troweling and saves time on labour and finishing surfaces.
linear relationship between the value of machine-made sand and the stone powder content. It can be seen from Table 2-5 that the selected machine-made sand has high calcium oxide content, all exceeding 40%, and the highest content is 51.43%. The silica content is the second, indicating that the machine-made sand is a calcium oxide rock.
