DESCRIPTION: Dry fine silica sand is used with low viscosity crack repair materials like Crack-Tite, Slab Repair Kits. Sand can be used with A-Tech 1300 in wider cracks to give a better look and finish to the repair. Fills wide cracks and gives body to A-Tech 1300.
Silica sand consists of well-rounded, sand composed of almost pure quartz grains. Quartz, or silicon dioxide (SiO2), is the most common mineral found on the Earth's surface and is found in rocks like granite, gneiss, and sandstone. The value of silica sand can be significantly higher than sand and gravel used in the con- struction industry.

Silica (SiO2) Colloidal silica, with sizes as small as 0.008 micron can be measured empirically by the SDI (Silt Density Index) test, but only that portion that is larger than 0.45 micron or larger. Particulate silica compounds (e.g. clays, silts and sand) are usually 1 micron or larger and can be measured using the SDI .
Recent particle size analysis of the Northern Silica Bunker Sand showed it to contain an acceptable total of 0.9 – 1.9% silt and clay which is within the recommended maximum of 3%. The sand was free of gravel which is ideal. The sand also contained acceptable 10.1-10.9% very coarse sand which is within the recommended maximum of 15%.
