in the framework of this study, which is part of a bigger project aiming to characterise the aggregates of cyprus, soundness tests have been carried out on samples obtained from 17 quarries situated all over the island, as shown graphically in fig. 1.the samples (see also table 3) comprised of crushed aggregates used locally in portland cement and asphalt concrete production, with grain sizes.testing the soundness of aggregates using different,highlights astm and en (weighted average) soundness tests with mgso 4 produce similar results. en soundness test (annex b) is not suitable for fine aggregates. mgso 4 is far more damaging than na 2 so 4. increase in mass loss for coarse aggregates with fraction size reduction.
in eu member states, the magnesium sulphate heptahydrate soundness test (en 1367-2)  is used, whereas in most of the us and some other countries in the world, the astm c88/c88m-18  sodium.aggregate testing equipment,properties like particle size, distribution, relative densities, soundness, chemical resistance etc., of aggregates are tested using different types of aggregate testing equipment. we offer air entrainment meter, aggregate impact value test apparatus, aggregate crushing value test apparatus, los angeles abrasion testing machine, flakiness & elongation index test gauges and other types of.soundness test on aggregate sample selection and,soundness test for aggregates (is-2386-part-5) aggregate samples are submerged in sodium sulphate or magnesium sulphate solution repeatedly. this process causes salt deposits in the aggregate pores which tends to break the aggregates.
scope and principle of test this test method covers the testing of aggregates to estimate the soundness of aggregates when subjected to weathering action in concrete or other applications. the sample of aggregates is subjected to repetitive immersion in a standard solution of sodium or magnesium sulfate followed by over drying..soundness test on aggregates,there are various tests are carried out to check the quality of the aggregate like abrasion test, impact test, soundness test, flakiness index test, etc. the soundness test on aggregate is carried out to learn the resistance of aggregates to weathering actions like thawing, freezing, alternate wetting and drying in normal conditions and in salt water, variation in temperature.

aggregates having more water absorption are more porous in nature and are generally considered unsuitable unless they are found to be acceptable based on strength, impact and hardness tests. water absorption shall not be more than 2 per unit by weight. in case in water absorption is higher than 2 than soundness test is required..soundness and sturdiness basket for aggregate,the soundness test basket is used to test the sturdiness (also called as the soundness) of aggregate. diameter (mm) mesh size. 7070. 0.08mm,0.16mm,0.315mm,0.63mm,1.18mm,1.25mm. 100100..aggregate testing services aggregate inspection company,aggregates can be obtained from different sources including natural sands and gravel from the sea, land, crushed rocks and artificially produced materials. they can be used for various purposes, such as a major component of concrete and asphalt roads, which makes aggregate and sand testing important.
precision 13.1 aggregates; magnesium sulfate; sodium sulfate; sound- ness; weathering 12.1 precision—for coarse aggregate with weighted aver- age sulfate soundness losses in the ranges of 6 to 16 for sodium and 9 to 20 for magnesium, the precision indexes are as follows: the american society for testing and materials takes no position respecting the validity of any patent rights.determination of aggregate impact value,the aggregate impact test determines the ability of an aggregate to withstand sudden loads. during sudden loads, the aggregates may break into pieces. hence to analyse to provide the adequate quality we perform this aggregate test. must read : aggregate crushing test to find strength of aggregate impact test relevant codes: is 2386(part 4 ): 1963
aashto t 103: soundness of aggregates by freezing and thawing this test method covers three procedures in testing aggregates to determine their resistance to disintegration by freezing and thawing. it furnishes information helpful in judging the soundness of aggregates subjected to weathering, particularly when adequate information is not available from service records of the behavior of the.7 lab tests on aggregates to make better concrete for,following are the different types of aggregate tests conducted to ascertain the suitability of aggregates: 01. crushing test on aggregates. 02. abrasion test on aggregates. 03. impact test on aggregates. 04. soundness test on aggregates. 05. shape test on aggregates. 06. specific gravity and water absorption test on aggregates. 07..test for aggregates for concrete,the most common soundness test involves repeatedly submerging an aggregate sample in a saturated solution of sodium or magnesium sulphate. the disintegration of aggregates is recorded. apparatus for determining aggregate soundness test sieves for fine aggregate : 150, 300, 600 micron and 1.18, 2.36, 4.00, 4.75 mm
