The sand equivalent is an indicator used in geotechnical engineering to characterize the cleanliness of sand; the main purpose of this test is to identify the percentage of fines in a sample. The test consists of pouring a sand sample and a small amount of flocculating solution into a graduated cylinder and shaking it to loosen the clay coatings from the sand particles. The cylinder is then topped up with the rest of the flocculating solution so that the fine particles rise in suspension above the sand. After 20 min, the heights are measured. The sand equivalent is the ratio of the sand height to the total height, expressed as a percentage
