Nov 16 2020 To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred The aggregate crushing value of the coarse aggregates used for cement concrete pavement at surface should not exceed 30 and aggregates used for concrete other than for wearing surfaces shall not exceed 45 as specified by Indian Standard IS and Indian Road
Aggregate Crushing Value Test Determine Aggregate Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road construction is expressed by numerical index
Aggregate Crushing Value Test Determine Aggregate 2010 5 5 Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions Aggregate crushing value is a numerical index of the strength of the aggregate and
Procedure for crushing strength of aggregate Before testing the aggregate should be in surface dry condition You can achieve the dry condition of aggregate by The aggregates passing through 12 5mm and retained on 10mm IS sieves are selected for finding aggregate crushing After sieving
May 18 2018 Factors affecting compressive strength of concrete Coarse aggregate Concrete is made homogenous by combining aggregates cement sand water and various other admixtures But even with proper mixing there may arise some microcracks due to differences in thermal and mechanical properties of coarse aggregates and cement matrix which leads to
Aggregate is a granular material obtained by processing natural materials BS882 splits aggregate into coarse and fine elements coarse being described as gravel or crushed rock and fine being described as sand Aggregate consists of particles of a rock of a controlled particle size distribution used in the construction of a building or civil engineering structure
Aggregate Crushing Value Test Procedure Aggregate Crushing Value Test Procedure 20191124one of the model in which pavement material can fail is by crushing under compressive stress a test is standardized by is2386 partiv and used to determine the crushing strength of aggregates the aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing
Coarse aggregate is used to describe particles larger than 4 75 mm and the term fine aggregate is used for particles smaller than 4 75mm Fine aggregates contain particles in the size range 75 m to 4 75 mm and coarse aggregates from 4 75 to about 40 mm except for mass concrete which may contain particles up to 150 mm
