Silica Test Sand for Cement and Field Density Testing

Standard test sand is selected for a defined laboratory or field procedure. Certified MTP offers graded cube-test sand, 20–30 silica sand and sand-cone density test sand. Choose by the required grading and application rather than treating every silica or Ottawa sand as interchangeable.

Graded Sand for Cement Mortar Cube Tests

Graded standard sand for cube tests, 50lb is listed in the No. 30–No. 100 sieve range, 600–150µm. It is the cube-test sand option for cement mortar work. Check the product documentation against the sand specification and test-method edition required by your laboratory.

20–30 Silica Sand

20–30 silica sand, 50lb passes the No. 20 sieve, 850µm, and is retained on the No. 30 sieve, 600µm. This narrower grading is distinct from graded cube-test sand. Select it only when the procedure calls for that sand type; do not substitute it solely because both products are described as standard silica sand.

Sand for Sand-Cone Density Tests

Sand-cone density test sand, 50lb is a separate product for field density testing. Its free-flowing characteristics support the test-hole volume measurement used by the sand-cone method. Follow the specified procedure for determining the sand's bulk density and apparatus correction; do not assume a universal density value.

Before Ordering Test Sand

Confirm the product grade, bag weight, required documentation and intended test. The term Ottawa sand identifies a testing-sand source or type, not a single grading suitable for every application. ASTM and EN sand specifications should not be assumed equivalent.

For the associated apparatus, compare field density test equipment. Follow the product safety data sheet and your workplace controls for crystalline silica dust during handling and storage.
