00:00I have removed the hard rock from OB and removed it from the small size of 65 to 75 size.
00:10Then, as per civiling and IS code, I have converted to 4.75 to 20 mm.
00:20Then, there are different parameters like cube test, flexural test, split tensile test.
00:30We have compared it with natural aggregate concrete.
00:35We have found that if we use this 100% of the strength of 28 days is equivalent to natural
00:46aggregate concrete.
00:48We have a large size of OB, as per as we can lift it.
00:53I have taken it with OB and taken it with a dump.
00:56This size is 65 mm to 75 mm.
01:03Then, manually, as well as jaw crusher, required size of 4.75 to 20 mm size.
01:10We have to take it with a small size of the standard.
01:13After that, we have compared to the test parameters,
01:18different parameters, different parameters,
01:20pull out test,
01:22flexural test, beam test, cube test,
01:26test it.
01:28After that, we have compared to natural aggregate concrete,
01:32compared to this type of and compared to that,
01:45and we have achieved our strength as well as natural aggregates,
