·Aggregate crushing value = W1/W2 100 e Results Values Any value less than 10 is considered a strong aggregate while a value above 35 would normally be termed a weak aggregate 2 Abrasion Aggregates Test Take sufficient coarse aggregate sample and ensure it is clean and free from dust fines and other contaminants
·Moreover the Pearson correlation of chemical compositions and physical and mechanical properties of coarse aggregates was analyzed by Statistic Package for Social Science SPSS software and results showed that Al 2 O 3 and SiO 2 can improve the properties of coarse aggregates whereas CaO had a negative effect on aggregate performance
·The term gravel coarse aggregate is used to define particles between 4 and 80 mm and the term sand fine aggregate for material that is finer than 4 mm but coarser Aggregate Crushing Value ACV this is the measurement of the resistance of aggregate to crushing by compressive force A test specimen 10 14mm
·The main objective of this research is to investigate experimentally the effect of crushed and uncrushed coarse aggregate on the properties of hardened concrete compressive strength by adopting the American Concrete Institute ACI and the British Department of Environment DoE methods Concrete mixes were designed concrete cubes and cylinders
·Aggregates are intensively used in civil and transportation infrastructures In specification ASTM C125 21 aggregates are defined as granular materials such as sand gravel and crushed stones or slag used with a cementing medium to form hydraulic cement concrete or specification JTG E42 2005 aggregates are defined as granular
4 Fineness Modulus also indicates the surface area of the aggregate Apparatus Balances The Balances used in testing the fine and coarse aggregate shall have readability and accuracy as follows For fine aggregate readable and accurate up to and for coarse aggregate readable and accurate up to Sieves The sieve cloth
·In this study the effect of coarse aggregate shape characteristics on the compactability and microstructural properties of asphalt mixtures was virtually investigated using a discreet element method DEM Results reveal there is a statistically significant correlation between coarse aggregate flatness elongation roundness and sphericity as shape
·Sasanipour H Aslani F 2020 Durability properties evaluation of self compacting concrete prepared with waste fine and coarse recycled concrete aggregate Constr Build Mater 236 117 540 Google Scholar Chen ZP Huang K Zhang XG Xue JY 2010 Experimental research on the flexural strength of recycled coarse aggregate concrete
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963 The apparatus used is Cylindrical measure and plunger Compression testing machine IS Sieves of sizes 10mm and Procedure to determine Aggregate Crushing Value i The aggregates passing through
