Aggregate Crushing Value and Its Test Procedure One of the test in which concrete material can fail is due to crushing under compressive stress Aggregate crushing test is standardized by IS 2386 part IV and used to verify the crushing strength of aggregates The aggregates should be oven dried which can passes through 12 5mm and retained on.Calculation of aggregate crushing value The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2 36mm sieve) to the total weight of sample expressed in percentage W1= Weigh of the total aggregates (Wa We) W2= Weigh of aggregates passing through 2 36mm IS sieve.
Aggregate Impact Values (AIV’s) below 10 are regarded as strong and AIV’s above 35 would normally be regarded as too weak for use in road surfaces Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar and indicate similar aggregate strength properties Aggregate Impact Value Test Specifications.Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements Crushing value of aggregates indicates its strength Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a economical performance.

The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually 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 subjected to a specified load under standardized conditions and the strength of the aggregate used in road.CE412A Construction Materials and Testing I Aggregates Aggregate Types and Processing Aggregate is a combination of sand gravel crushed stone slag or other material of mineral composition used in combination with a binding medium to form such materials as bituminous and Portland cement concrete mortar and plaster or alone as in railroad ballast filter beds and various.
Crushing Value Test (IS 2386 (Part IV)) The material for the test should consist of aggregate passing 12 5 mm sieve and retained on 10 mm sieve For other sizes the materials are separated on the appropriate sieves given in Table Table 10 Details of Aggregate Crushing Test for Non standard Sizes of Aggregate.Discussion of aggregate crushing value May 08 2013 aggregate crushing value w b w a 100 record the mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material safety precautions use hand gloves while removing containers from oven after switching off the oven to wear safety shoes helmet.
Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture To determine the technical requirements of crushing value of coarse aggregate used in PA mixture step loading compression tests were conducted on the mixtures of PA 13 and a control asphalt mixture AC 13 respectively.77 Aggregate Crushing Value And 10 Fines Value Number report the mean as the aggregate crushing value unless the individual results differ by than 007 times the mean value in this case repeat the test on two further specimens calculate the median of the four results to the nearest whole number and report the median as the aggregate.
Calculation of Aggregate Crushing Value The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 2 36mm and the weight of the dried aggregate sample At least three samples should be tested from the same batch and average value to get accurate results.Calculation of Aggregate Crushing Value The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 2 36mm and the weight of the dried aggregate sample At least three samples should be tested from the same batch and average value to get accurate results The crushing value of aggregate = (W2 W1) x 100 Lab Report.
