sand equivalent test . 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. 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,sand equivalent test set | controls group,the two sets are identical except for the four measuring cylinders which are totally graduated in the astm/aashto version and for the weighted foot which is slightly different. for a reliable test result we recommend the use of a mechanical shaker. see # sand-equivalent-shakers #. plastic bucket 9 l cap.
according to hveen (1955), the sand equivalent test (es) is a quick test to determine the presence of undesirable quantities of adverse minerals and materials such as clay, since an excess of clay is usually detrimental to the performance of any aggregate. the test consists of pouring a measured volume of fine aggregate and a small quantity of flocculation solution into a graduated plastic cylinder and agitating it to loosen the clay-like coatings from the sand particles in the test,studies of the free mica properties and its influence on,unbound granular materials. two standard methods: sand equivalent test and methylene blue test were assumed as the most sensitive to mica presence. both methods showed susceptibility to mica content and gave strong correlation in terms of mica content. the third paper enhances knowledge of the behaviour of mica rich
test results are illustrated which show the effect on the sand equivalent values of particular aggregate when the natural dust is replaced with crushed rock dust. the effect of fineness is graphically illustrated. it is concluded that the sand equivalent test is useful in detecting the presence of adverse amounts of clay in granular base materials. it may be used as a quick field test to control the amount of adverse clays in concrete sand…,block 7 fine aggregates 13 - slideshare,these are the plasticity index (oldest), sand equivalent test (from the 1950’s), and methylene blue (relatively recent). plasticity of fines has been used for a number of years to control the clay content of fine aggregate. in the superpave mix design method, the sand equivalent is also referred to as measuring clay content.
