Determine the percentage of fine aggregate in total aggregate by absolute volume from table for the concrete using crushed coarse aggregate. 6. adjust the values of water content and percentage of sand as provided in the table for any difference in workability, water cement ratio, grading of fine aggregate and for rounded aggregate the values jaw crusher.
The crushed aggregate is removed from the test specimen and sieve it through the 2.36 mm is sieve. an impact value is measured as of aggregates passed through the 2.36mm sieve w2 to the total weight of the sample w1. aggregate impact value the value of aggregate impact test = w1/w2100.May 17, 2019 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 construction is expressed by numerical index.The aggregate crushing value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied. test method: is: 9376-1979, is: 2386 p-41963. drying shrinkage: drying shrinkage is defined as the contracting of a hardened concrete mixture due to the loss of capillary water. this shrinkage jaw crusher.The objectives of determining the crushing value of aggregate products. as a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, the objectives of determining the crushing value of aggregate, quarry, aggregate, and different kinds of minerals.The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. aggregate crushing value 45 for aggregates used for concrete for non-wearing surfaces and 25 for wearing surfaces like runways and roadways.
Dec 19, 2014 calculation: • aggregate crushing value = b/a x 100 • the result should be recorded to the first decimal place and the mean of the two results reported. • to achieve a high quality of pavement, aggregate possessing low crushing value should be preferred. 8.The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. crushing value is a measure of the strength of the aggregate. the aggregates should therefore have minimum crushing value. 3. apparatus the apparatus of the aggregate crushing value test as per is: 2386 part iv – 1963 consists of jaw crusher.
These aggregate crushing value apparatus are comprised of automated technologies that offer precise analysis and details on the outcome of a test phase. these aggregate crushing value apparatus are equipped with hydraulics for conducting compression tests and come with distinct power capacities.
From the calculations done we came to know that the sargodha crush is a good aggregate and margala crush and the mixture of margala and sargodha are also close to the maximum allowable limit for good aggregates hence they can be acceptable as their aggregate impact value is less then 35.
The aggregate crushing value acv provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. two versions available: 150 standard and 75 mm dia. the apparatus comprehend cylinder, plunger, base plate, tamping rod and measure. cylinder, plunger and base plate are made from special alloy jaw crusher.

Calculations: aggregate crushing value = b/a 100 the value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. aggregate crushing value 45 for aggregates used for concrete for non wearing surfaces and 25 for wearing surfaces like runways and roadways.Oct 16, 2017 significance : the aggregate crushing value gives relative measure of the resistance to crush under a gradually applied compressive load. definition : it is defined as the ratio of the weight of fines to the total sample weight expressed as a percent when tested as per the is procedure.Of an aggregate to crushing. made of mild steel. the selection of proper aggregate for a. of appropriate aggregate from the wide range. rod, 16mm dia x 450 to 600mm length. 110mm internal dia x jaw crusher.
4000 psi, 5000psi. the process of concrete mix design and determination of aggregate crushing value according to aci 211.1aci 211.1, 2009 and bs 812-110 standards bs 812-110, 2009was used in.Aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. 3. apparatus the apparatus of the aggregate impact value test as per is: 2386 part iv – 1963 consists of jaw crusher.Crushed aggregate requires slightly higher values. fine aggregate content is usually 35 to 45 by mass or volume of the total aggregate content. characteristics of aggregates. the important characteristics of aggregates for concrete are listed in table 5-2 and most are discussed in the following section: grading. grading is the particle-size jaw crusher.
