20-30 Silica Sand (Tensile Test Sand), 50lb

20–30 Silica Sand (Tensile Test Sand), 50lb

20–30 silica sand is a laboratory test sand supplied in a 50lb bag. This grade is selected for test procedures requiring 20–30 standard sand, rather than pool-filter sand or a different laboratory sand grading.

Grade and Packaging

Sieve grading: passes the No.20 (850µm) sieve and is retained on the No.30 (600µm) sieve. Package: 50lb bag. Material: naturally rounded, high-purity quartz silica sand.

Laboratory Selection

The product is identified as ASTM C778 20–30 standard sand and is commonly described as tensile test sand. Former ASTM C190 references describe a discontinued method, not a current test requirement. Confirm the sand grading called for by your laboratory procedure before ordering.

Do not interchange this grade with graded cube-test sand solely because both are silica sand. Differences in particle-size distribution matter when preparing standardized test mixtures.

Handling

Avoid generating or breathing dust and follow the current safety data sheet and workplace exposure controls. Browse laboratory supplies for related sample-preparation needs.
