The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i) The aggregates.Tests were conducted on coarse aggregates to determine the different physical properties as per IS 2386 (part III)-1963. This test were conducted for 20 mm size aggregate. They were considered as per IS 383-1970. The specific gravity of aggregate was found to be 2.7 1. 1) Shape Angular 2. 2) a) Loose bulk density 1439 kg cu.m. 3) b) Dry rodded.
The coarse aggregate grading limits are given in ASTM C33 C33M and IS 383 – 1970 - table 2, Clause 4.1 and 4.2 for single size aggregate as well as graded aggregate. Material strength of coarse aggregate is indicated by crushing strength of rock, aggregate crushing value, aggregate impact value, aggregate abrasion value.Jan 01, 2021 The aggregate crushing value for Natural coarse aggregate is found to be 14.85 and that of E-Waste is 2.3 . Both the aggregates possess the value less than 30 and it is within the limits specified by IS 383 1970 . It can be concluded that E-Waste have resistance to the wear and tear than the natural aggregate. 3.2. Impact value test.

Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30 or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source IS 2386 (Part 4) 1963).Aggregate. Locally available coarse aggregate having the maximum size of 20 mm was used in our experiment. The aggregates are washed to remove dust and dirt and were dried to surface dry condition. The coarse aggregates are tested as per Indian Standard Specifications IS 383-1970. Table -4 Properties of Coarse aggregates Sr.

The size of aggregate was kept between 10 mm to 20 mm which were used for casting. The debris are manually broken down. The properties of fine and coarse aggregates obtained experimentally as per IS 383-1970  is presented in Table 2. Table 2.

Mar 12, 1984 aggregate crushing aggregate impact value and aggregate abrasion value shall not eiceed the corresponding requirements laid down in IS 383-1970tt for concrete for wearing surfaces. The aggre- gate impact test shall be done only as an alternative test to aggregate crushing test. Rules for rounding off numerical values ( revised ).The impact value of an aggregate may be used as an alternative to its crushing value. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance of gradually applied compressive load. Impact strength of coarse aggregate as per IS2386-part IV-1963.
The results obtained are presented in graphical form The 20 mm 10 mm nominal sizes of coarse aggregates were taken as per IS 383-1970.The A) CBR value of soil without mixing coarse aggregates having impact value 9.86 and crushing aggregates value as 11.21 shows that the coarse aggregates At OMC 26.78 collected can withstand relatively.Test Method IS 2386 (P-1) 1963, ASTM C136-2006, IS 383-1970.

Value, aggregate crushing value, flakiness index, elongation index and Los Angeles abrasion value were conducted as per the IS 383 (1970). All the test results are discussed in section 4.Dec 13, 2019 Veera Reddy reported on impact value and crushing value of ceramic scrap as 18.2 and 24.7 respectively. These values were within the permissible limits according to IS 383-1970, hence it was safe to use as a coarse aggregate in concrete composition.
