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 it .
The LA abrasion method suffers from several drawbacks including the time needed to perform the test, the operational noise and dust and the space required by the machine. The objective of this study was to investigate whether the modified compaction method can be a suitable alternative for determining the LA abrasion value.
Jan 04, 2014· Procedure of testing Aggregate Crushing Value (ACV): 1. Make a sieve analysis and get sufficient amount of aggregate by using mm passing sieve and mm retained sieve. 2. After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm. 3.
An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger. The specimen is then loaded via the plunger. The load crushes the aggregate to an extent depending on the crushing resistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value (ACV).
Aggregate Crushing Value engineeringcivil. Procedure to determine Aggregate Crushing Value i) The aggregates passing through 125mm and retained on 10mm IS Sieve are ovendried at a temperature of 100 to 110 o C for 3 to 4hrs ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod

crushed aggregate requires slightly higher values. Fine aggregate content is usually 35% to 45% by mass or volume of the total aggregate content. CHARACTERISTICS OF AGGREGATES. The important characteristics of aggregates for concrete are listed in Table 52 and most are discussed in the following ... The 13 standard sieves for coarse aggregate ...
This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone brick khoa of aggregates.
