The coarse recycled concrete aggregate was obtained by crushing a laboratory produced primary concrete at age of 28 days. About 250 cubes of dimension 15 ∗ 15 ∗ 15 cm were crushed to produce the recycled coarse aggregates using mix design ().After crushing of these cubes, the maximum nominal size of recycled coarse aggregate used in mixes 2, 3 and 4 was 25 mm.

Aug 30, 2019· The fine aggregates used in this study are silica sand. Three types of coarse aggregates are used: NA, RCA, and RAP. The photos of aggregate used are shown in Fig. 1. The RCA used in this study was obtained by crushing specimens of old cubes and RC beams. The age of the specimens ranges from 6 months to 1 year.
Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
Jan 23, 2018· PURPOSE OF TEST: The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load. Lesser the aggregate crushing value greater will be the "resistance to crushing under gradually applied compressive load".

Jul 06, 2015· Sieve analysis is done to check the gradation of aggregate. The test is done as follow. Take required amount of aggregate sample (for coarse aggregate take apprx. kg and for fine aggregate take kg) Arrange the required no of sieves as per the contract or job requirement in an descending manner.
aggregate and determining its mass by displacing a mass of water. The result is the ratio of the density of the aggregate to the density of water. The appropriate test method depends on the size of the aggregate being tested. For coarse aggregates the test is performed in accordance with AS or AS with aggregate
The crushing strength test discussed above has been found insensitive to the variation in strength of weaker aggregates. Therefore when such aggregates are tested by this method, they do not give true picture, because they get crushed before the full load of 40 tonne has been applied and get compacted causing the plunger to jam.
