The appropriate test method depends on the size of the aggregate being tested. For coarse aggregates the test is performed in accordance with AS 1141.6.1 or AS 1141.6.2 with aggregate

Effect of aggregate size on the restrained shrinkage of

2017-12-7 strength and maximum aggregate grain size are inverse ratio with the help of the comprehensive test so the bigger aggregate causes weak concrete. The effect of the maximum aggregate grain size on the development of the crack is defined as; 1. When the crack runs into the aggregate, it travels around the aggregate on the same way.
