poor quality aggregate) was obtained, the performance in concrete was sufficient. The sand equivalent test relies on apparent density differences between "good" sand fines and "bad" clay fines. Even though a flocculant is used to further encourage separation of clay particles, similar sized sand .
When aggregates with clay coatings are used for concrete mixing, a portion of. the clay will enter the water phase before the dry cement is added. The degree of. .
In readymixed concrete plants (RMC) and independent laboratories in Riyadh, the practice of determining the amounts of fine materials in fine aggregates is either by ASTM C 117 (materials finer than No. 200 sieve by washing) or ASTM D 2419 (sand equivalent test) and sometimes both.
The sand equivalent test is used to limit the presence of clay material in the aggregate. The sand equivalent test ( AASHTO T176; ASTM D2419 ) is a rapid field test to show the relative proportions of fine dust or claylike materials in fine aggregate (or granular soils).

Standard Test Section: AGGREGATES Procedures Manual Subject: SAND EQUIVALENT 1. SCOPE Description of Test This method describes the procedure for determining the sand equivalent of granular material. Application of Test The purpose of this test method is to indicate, under standard conditions, the relative ...
METHOD OF TEST FOR SAND EQUIVALENT CAUTION: Prior to handling test materials, performing equipment setups, and/or conducting this method, testers are required to read "SAFETY AND HEALTH " in Section I of this method. It is the responsibility of the user of this method to consult and use departmental safety
Sand equivalent test. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 9338. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that there is less clay‐like material in a sample.
• Sand Equivalent test is important because it is a simple test to determine whether a particular aggregate has enough dust or plastic fines to make a HMA mixture unstable or susceptible to stripping is valuable in preventing the manufacture of poor performing ... o calculating the void content in compacted asphalt concrete.
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. Components may be ordered as replacement parts as listed .
Fine aggregate will be subjected to the Sand Equivalent Test (Test Method Tex203F). The sand equivalent shall not be less than 80 unless otherwise shown on the plans. For all classes of concrete, except class K, the fineness modulus shall be between and as determined by Test .
The Sand Equivalent Test indicates the relative portion of undesirable claylike or plastic fines and dusts that occur in granular soils and fine aggregates passing the No. 4 sample to be tested is placed in a special solution of calcium chloride, formaldehyde and glycerine.

of materials used in concrete to obtain a good quality concrete. The characterization of manufactured sand is explained in this chapter. TEST DETAILS To characterize the manufactured sand, the following tests were conducted and compared with the properties with natural sand (NS). 1. Hydrometer analysis 2. Laser particle size analysis 3.
To provide a completely uniform shaking action at the specified rate and also eliminating any operator fatigue. In the version 47T0056/C, conforming to CE directive, the machine stops automatically when the safety cover is opened.
