Sand Equivalent Test Sets are used to indicate the relative proportions of clay-like fines in granular soils and fine aggregates. Gilson sets include everything required in ASTM and AASHTO test methods to conduct the test except the shaker. Each component is also available separately as an accessory.
Do not let the slurry dry on the concrete because it will harden in place. If you only have a small area to sand, you can also use a palm sander, orbital sander or belt sander. Rough imperfections may require the use of a special diamond disc and a concrete floor grinder.

Sand Equivalent Testing Laboratory or field test shows relative proportions of clays and fines in granular soils, sand or aggregate fines. Claylike materials remain suspended while heavier materials settle.
5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate. 5.3 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement.
Stock Solution for Sand Equivalent Test is a concentrated calcium chloride solution which is diluted with distilled water to create the working solution for conducting Sand Equivalent Tests. To create the working solution, mix 85ml of solution for every gallon of distilled water. The concentrated stock solution has a shelf life of only three months once the container is opened.
1. Prepare sand equivalent test specimens from the passing No. 4 sieve portion of the material to be tested after it has been processed according to the procedures prescribed in California Test 201, except that reclaimed aggregate containing traces of asphalt or asphalt concrete shall not be oven dried at temperatures greater than 100˚F.

General Provisions 101 through 150. 1. Concrete and Mortar Use fine aggregate for concrete and mortar that consists of natural sand, manufactured sand, or blends of natural and manufactured sands, having hard, clean, strong, durable, uncoated particles, meeting the requirements of the Specifications.
Comparatively, the ASTM's allowable silt and clay content in sand used for concrete production is 10% by weight. 15 samples met this limit, implying a failure rate of 44.4% of the tested sand samples by ASTM's standard. From Figure 11, the maximum silt and clay content registered from 27 samples was a .
Because concrete sand is available in a number of sizes from 4.75 mm throughout to a #200 sieve it is often recommended for this purpose. More commonly, though, professionals will recommend that property owners work with polymeric sand. This material has become extremely popular in recent years. The sand is coated with a water-activated polymer.

ASTM C1293: "Test Method for Concrete Aggregates by Determination of Length Change of Concrete Due to Alkali-Silica Reaction". It is a long-term confirmation test (1 or 2 years) at 38 °C in a water-saturated moist atmosphere (inside a thermostated oven) with concrete prisms containing the aggregates to be characterised mixed with a high ...
SAKRETE Sand Mix is a purpose product designed for a variety of projects ranging from repairing wide cracks in concrete and masonry to creating mortar beds under ceramic tile installations. It is a pre-blended mixture of sand and cementitious material that is ideal for applications from 1/2 in. to 2 in. Simply add water and mix for ready application.
This research included a study of the existing test methods (sand equivalent and loss by decantation) used to detect clay in concrete aggregates, and a study of the effect of various amounts of clay with various liquid limits on the strength, shrinkage, and freeze-thaw dura bility of concrete.
Sand equivalent tests serve as rapid field-correlation tests to show relative proportions of clay-like or plastic fines and dusts in granular soils and fine aggregates. The test separates sand and clay, a comparative reading is determined between the suspended clay and the settled sand .
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.).
