Aggregates ppt - SlideShare Apr 28, 2013· 7(1) Fine Aggregates:Aggregates whose particles passthrough 475 mm IS sieve are termedas fine aggregat Most commonlyused fine aggregates are sand (pit orquarry sand, river sand and sea sand)and crushed stone in powdered form,how ever some times sukhi and ,
Coarse Aggregates Fine Aggregates | Types, Uses and , Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar Those particles that are predominantly retained on the 475 mm (No 4) sieve, are called coarse aggregat
WHAT ARE THE PROPERTIES OF AGGREGATES FOR CONCRETE , Physical Properties of Aggregates 4 Coarse Aggregate Angularity • Measured on + 475 mm material • Based on fractured faces – fractured surface larger than 25% of aspect ratio • ASTM D 5821 • Specification requirements depend on: – depth of layer within pavement
Properties of Stone Aggregates - Civil Engineers PK To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material The expanded material has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete product
Concrete Physical Properti Mechanical Properties , Concrete Physical & Mechanical Properties 14 •Clean & sound •Abrasion resistance • Freeze & thaw resistance • Wetting & drying properties •Chemical stability •Alkali aggregate reactivity • Shape and surface texture • Aggregate grading Characteristics of Aggregate Bridge Engin eering Section Technical Standards Branch BIM
Mechanical Characterization of Aggregates - KTH Mechanical Properties of Aggregates [email protected] California Bearing ratio (CBR) Value Basically a penetration test Piston penetrates soil at constant rate 005 in/min Pressure is recorded Take the ratio to the bearing capacity of a standard rock Range: 0 (worst) –100 (best) Type equation here CBR= Pressure to cause 01” penetration to the .
