The gravel from sand and gravel mining waste has not been used optimally as a building material. Based on these reasons, it is necessary to conduct research on the utilization of gravel from mining waste as a substitute for standard gravel in concrete mixtures.

The weight ratio between standard gravel and gravel from mining waste used is: 100:0, 70:30, 60:40, 50:50, 40:60, 30:70, 20:80, 10:90, and 0:100. The test carried out on fresh concrete is a slump test, and on hardened concrete is a compressive strength test.

From the results of this study it can be concluded that: the coarser the gradation and the greater the fineness modulus (FM) of coarse aggregate will increase workability and reduce compressive strength. The gradation and fineness modulus of coarse aggregate have no effect on the unit weight of the concrete. Gravel from mining waste can be used as a partial substitute for standard gravel.
