<strong>EXPERIMENT</strong> <strong>NO</strong><br />
<strong>AIM</strong> :- <strong>To</strong> determine ab rasion value of coarse aggregate by Los Angelis Abrasion<br />
Testing Machine.<br />
APPARATUS :-<br />
FIGURE :-<br />
THEORY :-<br />
PROCEDURE :-<br />
Los Angelis Abrasion Testing Machine , aggregate , cast iron , spear , 17<br />
mm sieve<br />
The principle of Los Angelis Abrasion Test is to find out<br />
percentage valu e due to the relative rubbing action between the aggregate<br />
and the steel ball which are used as an ab rasion char ge .<br />
The <strong>test</strong> procedure co nsists of a rotating drum . It is rotated<br />
at a speed of 20 – 30 rpm . In this cylinder the sample along with the balls<br />
is added . The total weight of sample depends upon the size of aggregate<br />
and number of steel balls and weight of each steel balls . Maximum weight<br />
of steel ball is limited to 5 Kg . The sample and the steel ball are rotated<br />
upto 500 revolution . After completion of revolution , the sample is taken
