FIGURE :- EXPERIMENT NO AIM :- To determine the crushing value of aggregate by aggregate crushed test APPARATUS :- FORMULA :- Steel cylinder of 152 cm diameter with a base plate and and plunger compression testing machine , sieves , aggregate etc. % Crushing Value = [W3 / (W2 – W1 )] x 100 Where W1 = Weight of empty mould = __________ Kg W2 = Weight of mould + Aggregate = __________ Kg W3 = Weight of pan + crushed aggregate = ___________ Kg
THEORY :- PROCEDURE :- OBSERVATION :- CALCULATION :- RESULT :- PRECAUTION :- APPLICATION :- The strength of coarse aggregate may be determine by aggregate crushing strength test . The aggregate crushing value provides a relative measure resistance to the crushing order .Gradually applied compression load , to achieve a high resistance to crushing or low aggregate crushing value are performed . Dry aggregate passin g through 12.5 mm sieve and retained on 10 mm sieve is filled in the cylinder in three layers . Each layer being compacted b y 25 blows of tamping rod of diameter 16 mm.Then the plunger is placed on the top of the specimen and a load of 40 ton es/ min is applied b y the compression machine .The crushed aggregate are removed and sieved in 2.35 mm sieve . The material which passes through this sieve is weighed (Ws ). The value of aggregate is in percentage o f crushing material passing through 2.35 mm sieve in term of original weight of specimen . W1 = Weight of empty mould = ___________Kg W2 = Weight of mould + Aggregate = __________ Kg W3 = Weight of pan + crushed aggregate = ___________Kg % Crushing Value = [W3 / (W2 – W1 )] x 100 The crushing value of the given aggregate is found to be ___________ % 1)Length of the three layers should be approximately equal . 2)Aggregate should be perfectly dry . 3)Mould should be perfectly dry and clean . 4)Sieving should be done carefully. Stone aggregate gives low crushing value . The crushing value of good quality aggregate to be used in base coarse should not ex ceed 45 % and the value for the surface co arse should not be less than 30 %.
