ASTM Test Sands are specially graded for ASTM tests. The naturally rounded silica sands of nearly pure quartz are mined from the Ottawa, Illinois area. Three different gradings are available, each designed for a specific type of test.
HM-106 Sand Cone Density Test Sand for sand cone density testing of soils is clean, uniform, uncemented and free-flowing, and meets ASTM D1556/1556M and AASHTO T 191. Few particles pass No. 200 (75μm) or are retained on No. 10 (2.00mm) sieves. Uniformity coefficient less than 2.0, and less than 3% passes No. 60 (250µm). Bulk density varies less than 1%.
HM-107 20-30 Standard Tensile Test Sand is manufactured to pass No. 20 (850µm) sieve and be retained on No. 30 (600µm). It meets ASTM C 778 and AASHTO T 132 requirements, and also complied with ASTM C190, now a discontinued standard.
HM-108 Graded Standard Cube Test Sand is graded between No. 30 (600µm) and No. 100 (150μm) sieves. Meets requirements for ASTM C 109 and C 778, as well as AASHTO T 106.
All are supplied in 50lb bags and meet ASTM and AASHTO standards indicated.
