Quick mix research and development center offers a wide range of testing in concrete raw material to ensure the quality of our produced concrete. The laboratory division further divided into sections function under strict quality control procedure using calibrated equipments operated by well experienced section supervisor and trained technicians.
10% Fine Value. This test is a measure of the strength of aggregate, which will normally be used in making concrete. It involves compression in a mould of a known mass of aggregate of single particle size and measuring the load required to reduce 10% of the particles to fine material.
sand equivalent value soil fine aggregates (astmd2419) Suryakanta | October 17, 2015 Sand Equivalent Value Test Purpose To determine the percent of undesirable particles in the fine aggregate fraction used in the design of Portland cement concrete mixtures.
ASTM D 2419: Sand Equivalent Value of Soils and Fine Aggregate; Summary. A small sample of fine aggregate passing the No. 4 ( mm) sieve is placed in a graduated cylinder and mixed with flocculant solution to separate fine dust of claylike particles from the rest of the aggregate sample. The sample is shaken and then allowed to sit for 20 minutes.
Laboratory testing is useful. It's useful for making sure that everything is as it should be on any construction project. That's why we offer a wide range of concrete and soil testing at Perry testing Ltd.
Since early 2007 Building and Construction Authority of Singapore (BCA) has adopted a threestage testing regime on imported aggregates to determine the quality of aggregates imported from overseas sources. Since beginning, Admaterials has provided imported aggregate testing .
limits, it may be used, provided its Ten Percent Fines Value (Wet) is at least 60 kN greater than the specified maximum value for the relevant aggregate quality category. b) The Ten Percent Fines Value (Wet) and the Wet/Dry Strength Variation tests shall be carried out on predominant size fraction represented within the sample.

The test aims at looking for the forces required to produce 10% of fine values ( weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
