The crushing strength of road aggregates as an essential requirement in india. crushing strength of road stones may be determined either on aggregates or on cylinderical specimens cut out of rocks. these two tests are quite different in not only the approach but also in.
Concept and significance of the aggregate crushing value test. the aggregate crushing value test giveselative measure of the resistance of an aggregate to crushing underradually applied compressive load. aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are.
The crushed aggregate sample which is finer than 2.36 mm is separated and expressed asercentage of the original weight taken in the mould. the percentage of weight passed through the 2.36m is sieve is known as aggregate crushing value.. in situations, when the aggregate value 30 or higher the result may beistake and in such cases, the ten percent fines value.
Aggregate crushing value test. 10 aggregate crushing value test introduction the principal mechanical properties reired inroad stones areatisfactory resistance crushing value apparatus, aggregates testing equipment, controls.
Crushing strength of road stone may be determine either on aggregates or on cylindrical specimen cut out of rocks. the two tests are quite different not only in the approach but also in the expression of the results. aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads.
Procedure of aggregate crushing value test. sieve the test material through 12.5 mm and 10.0 mm is sieve. take test samples of aggregates passing through 12.5 mm is sieve and retained on 10 mm is sieve minimumg. dry theme in an oven forours atemperature of 100o 110nd then cool at room temperature.

Crushing test or compression strength test on stone. the crushing strength or compressive strength is given by the formula asa. where,ompressive strength.oad at failure.rosssectional area of bearing face of the specimen. then the average value of the six specimens is calculated and the result is recorded for that stone.
Crushing strength test for conducting this test, specimen of size 40 40 40 mm is build from parent stone. then finely the sides are dressed and placed in water for three days. the saturated specimen is provided havingayer of plaster of paris on its bottom and top surfaces to get even surface so that load applied is uniformly distributed.
Basically, stone testing calculates the fitness ofarticular stone forpecific application. as far as the potency of the stone is concerned, testing lets you know more about the ability of the stone to resist bending and crushing. the density and gravity test decides the ability of the stone to carry the weight of the stone.
Different tests on mortar.rushing test.ensile strength test.dhesive test. related posts share this mortar is an intimate mixture of binding material, fine aggregate and water. when water is added to the dry mixture of binding material and the inert material, binding material develops the property that binds not only the.
A minimum of three specimens should be used for testing. procedure specimen is immersed in water at 20 to 30or 72 hours. test in saturated condition specimen is dried in an oven at 105 for 24 hours. test in dry condition then it is cooled inesiccator to 20 to 30 c. later, it is tested in universal testing machine.
Organization. note that stone testing according to european methods and conditions may use different procedures that give different results than do astm methods for the same stone. this is particularly true of tests for abrasion wear. the astm standard test methods are listed in.

Aggregate crushing value test on coarse aggregates giveselative measure of the resistance of an aggregate crushing under gradually applied compressive load. coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected topecified load under standardized conditions.
A testing machine of sufficient capacity for the tests and capable of applying load at the specified rate should be used. take three cylindrical test pieces of diameter greater than or equal to 50 mm.
Crushing test the maximum load at which the sample crushes or fails divided by the area of the bearing face of the specimen gives the crushing strength of stones. impact test for determining the toughness of stone, impact test is being performed on page impact test machine. abrasion test this test is performed on los angeles apparatus.
D apparatus of crushing test compressive testing machine crushing mouldteel cylinder 15 cm diameter with plunger and base plate. weighing machine, sieve size of 12.5 mm, 10 mm and 2.36 mm the crushing mould is filled in three layers with aggregates. then the weight w1 of the aggregate in the crushing mould is noted.
