Fine Sand Sand used in GFRC should have an average size passing a 50 sieve to 30 sieve 0.3 mm to 0.6mm. Finer sand tends to inhibit flowability while coarser material tends to run off of vertical sections and bounce back when being sprayed. Cement Typical proportions use equal parts by weight of sand and cement.
