in the aggregate, whereas the Sand Equivalent results give an indication of amount and activity of the clay size fraction. A linking parameter is needed to draw a correlation between the two tests, and the liquid limit of the clay size fraction was chosen to satisfy this need. Fifteen samples of concrete sand from various loca
whereas the sand equivalent results give an indication of amount and activity of the clay size fraction. A linking parameter was needed to draw a correlation between the two tests, and the liquid limit of the clay-size fraction was chosen. Fifteen samples of concrete sand from various locations in Texas were obtained.
the texas highway department currently uses the results of sand equivalent and loss by decantation tests as a means of detecting such clay and controlling the quality of fine aggregate used in portland concrete cement. as an alternative to this, the sand equivalent test which separates the finer clay
Aug 11, 2011 Hi, What is the difference between sand equivalent test values and sa simple silt content test I mean when you finish a SE test, specs say that min 75 SE value is accepatable, which means max 25 of claysilt content is acceptable limit for sand used in structural concrete
Plastic Concrete The primary influence of clay on the plastic concrete was manifest in the amount of water required to main tain a given slump. The water-cement ratio for a 5-sack mixture with a 3-in. slump varied from an average of 0. 56 to 78 by weight when the sand equivalent value changed from 100 to 30 Fig. 1.
Comparatively, the ASTMs 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
The sand equivalent test indicates the relative proportions of clay-like fines in granular soils and aggregates. The manual shaker works best for use on the job site to give more uniform shaking action. Uniform shaking action pushes the top frame by a simple stroke of the hand. The portable unit features a

Sand Equivalent Test Kit Sand Equivalent tests provide rapid field-correlation tests to show relative proportions of clay-like or plastic fines and dusts in granular soils and fine aggregates. A test separates sand and clay and determines between the suspended clay and the settled sand in the measuring cylinder.

2019-5-28 The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8.1 The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not.

Apr 30, 2011 So if your sample has a 90 sand equivalent that means that 90 of the sample was good material and 10 was detrimental. If you have a 40 sand equivalent that means that 40 of the sample was good material and 60 was detrimental. Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE.
1.4.5 Sand Equivalent The sand equivalent shall not be less than 25 when the aggregate is tested according to NZS 44071991 Test 3.6 Sand Equivalent Test. The sand equivalent test may be omitted if the grading test shows less than 4 passing the 75 micron sieve. 1.4.6 Grading Limits
