Aggregates for Concrete
CHAPTER 1—INTRODUCTION. Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.
The Complete Guide to Crushed Stone and Gravel
Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
Test on Coarse Aggregates
This test is conducted to determine the crushing strength of aggregate. This test helps to assess the suitability of aggregates for use in road construction and other applications where they are subjected to high compressive stresses. The specifications for this test are given in IS : 2386 Part IV 1963 mechanical properties.
