value of sand equivalent characterize the fine aggregate as "dirty" and indicates that possibly the clay materials are harmful. The test is carried out on the 0/2mm fraction in fine aggregates ...
85 What is L.A. Abrasion? Indication of coarse aggregate resistance to abrasion and mechanical degradation during handling, construction, and use
Standard JTG E42-2005 / T0334. Application The instrument is used to test the sand equivalent value(SEV) of fine aggregate.
A higher sand equivalent will be obtained for cleaner aggregate. For the purpose of this study, three different methods were used to determine the SE value: the SE test according to SIST EN 933-8 on the <2 and <4 mm content and the SE test modified from the former Yugoslav standard (JUS U.B1.040), using <4 mm and not <4.75 mm as originally specified. The results are given in Table
2016-12-14· 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 …
This test method is intended to serve as a rapid fieldcorrelation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve.
The sand equivalent test, described in the Test Description section, separates out a fine aggregate sample's sand and plastic fines and dust portion to determine the content of the latter. lower sand equivalent values indicate higher pastic fines and dust content.
5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike fines in an aggregate. 5.3 This test method provides a rapid field method for
1. Scope. 1.1 This test method is intended to serve as a rapid field-correlation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-like or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve.
