EXPERIMENT NO AIM :- To perform water absorption test ... - Raisoni

CALCULATION :-
RESULT :-
PRECAUTION :-
DISCUSSION :-
Weight of empty container = W1 = _____ Gm
Weight of soaked aggregate + Weight of container = W2 = _____ Gm
Weight of oven dried aggregate + Weight of container = W3 = _____ Gm
Water absorption in % = [ ( W1- W3 ) / ( W2- W1 ) ] x 100
Percentage of water absorption for a given sample of aggregate is found to
be _________ %.
1) The aggregate must be immersed properly in water for 24 Hrs .
2)The water from surface of aggregate must be dried .
3)Weight the aggregate carefully in spring balan ce.
Rock specimen having more than 0.6 % water absorption
values are considered unsatisfactory unless found acceptable based on
strength test . However slightly higher value of porosity may be acceptable
for aggregate used in bituminous pavement construction if aggregate is
found otherwise suitable.
