Abstract The relatively low strength and brittleness are believed to be two main factors restricting the widely use of coal reject concrete (i.e. CRC) in practical applications.

The systematic compression tests on natural aggregates concrete (i.e NAC) and CRC with the large range replacement ratios of natural a...
