production control requirements will be removed from the aggregate during the test. Sand Equivalent Organic Impurities in Fine Aggregates for Concrete Section 801 Fine Aggregate Welcome to the GDOT. This section includes the requirements for fine aggregate. Concrete sand that passes the No. 10 Sand equivalent 70 or .
The Sand Equivalent Test Method As a standard test method described in ASTM D2419 and AASHTO T 176 the sand equivalent test is now widely used to measure the relative proportions of undesirable fines in aggregates and granular soils.
Higher sand equivalent values indicate cleaner less fine dust or clay-like materials aggregate. Typical sand equivalent values range from less than 30 to more than 90. If agg. 1 has SE 70 and agg. 2 has SE 40 that means agg. 1 has more sand and less clay like material than agg. 2. The sand Equivalent in base material should be at least 45. Solution reading Clay reading Sand

Apr 30 2011 Sand Equivalents. According to Caltrans test method 217-Sand Equivalent The sand equivalent test provides a measure of the relative proportions of detrimental fine dust or clay-like material in soil or fine aggregates. Fine dust 200s and smaller and clay material in aggregates can be detrimental to the performance of hot mix asphalt for a variety of reasons.
Sand Equivalent and Loss by Decantation tests as a means of detecting such clay and controlling the quality of fine aggregate to be used in portland cement concrete. Article 421 of these specifications presently states The loss by decantation of fine aggregate in
It is most commonly used to as a key ingredient in cement or hot asphalt but can also be used as pipe sand or as a base layer and leveling medium for above ground pools and patios or walkways made of concrete paving stones. Mason Sand. Mason sand is created in the same way as concrete sand but is crushed finer. It is also created at the quarry by crushing granite gneiss limestone or trap rock then
Aggregates comprise as much as 60 to 80 of a typical concrete mix so they must be properly selected to be durable blended for optimum efficiency and properly controlled to produce consistent concrete strength workability finishability and durability Photo 1. The ingredients in conventional concrete mixes usually fall within these .
Sand is a loose granular finer aggregate material. Two common types of sand are naturally occuring sands and manufactured sands which are produced by crushing larger aggregate into sand. Manufactured washed sands are an essential ingredient for concrete production as it can produce strengths exceeding that of less angular natural alluvial sands.
The fine aggregate will typically consist of natural sand crushed stone sand crushed gravel sand stone dust or arable powder fly ash and broken brick burnt clay. It will be hard durable chemically inert clean and free from sedimentary coatings organic materials etc. and will not contain any appreciable amount of clay shells or .
Sand equivalent is used to test clay content which is the percentage of clay material contained in the aggregate fraction that is finer than a 4.75 mm sieve. It is measured by ASTM D2419 Standard Test Method for Sand Equivalent Value of Soil and Fine Aggregate or AASHTO T176 Plastic Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Test.
2. Calculate the percentage of fine and coarse sand in the composite. a.
