You will not achieve 100%. You will not achieve close to 100%. 100% is what some sledge hammer thing does to a couple of buckets of soil over the course of 15 to 30 minutes with some guy standing there adding water until it's perfect. You will be lucky to get 93% with standard effort. That gets you about 10% loss in volume.

This volume is then weighed to the nearest 0.1g (mass A). 4. The material from the measuring cylinder is placed in the test cylinder in three layers, each tamped 25 times with the rod.

If our problem had covered a crushing condition calling for 80 instead of 85% passing the opening ...
read moreTo conduct crushing strength test we need compression testing machine, cylindrical measure, plunger and Isa sieves. First sieve the sample aggregate, aggregate passing 12.5mm sieve and retaining 10mm sieve is oven dries at 100-110 o C for 3-4 hrs. The cylinder is filled with aggregate in 3 layers, 25 strokes of tampering for each later.

read moreAggregate Crushing Value (ACV) test indicates the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through 2.36 mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken.

read moreThe crushing process produces agglomerations of the original concrete’s aggregates with adhered mortar. These agglomerations are, typically, more angular than conventional aggregates. Also the crushed concrete will produce fines from the mortar element, the amount being controlled to a large extent by the strength of the original concrete.

The reported results showed that the natural carbonation depth of C30 concrete after 20 years and 80 years were only 10 mm and 20 mm, respectively .
