Effect of recycled concrete coarse aggregate from multiple sources ...

The aggregate crushing value was measured in accordance with the British Standard 812-110 (1990) [12]. The main principle of the test is to compact and crush a loose aggregate specimen in a test cylinder by applying a constant load rate of 40 kN/min through a plunger. After the load reaches 400 kN, the applied load is ...
