The implementation of scale and steel chips waste as a replacement for raw sand in concrete manufacturing

For comparison between the thicknesses of mixed concretes and ordinary concrete, we first determined the thickness of OC-0 corresponding to the thickness of concretes with a scale and steel chips waste admixture using lead equivalent (LE). The experimental results were at once rewarding and promising. The results obtained demonstrate a tendency for the thicknesses of mixed concretes to decrease as the mixing ratio of scale and steel chips waste aggregate increases. The data shows that concrete mixed with steel chips waste have better strength than ordinary concrete, while in the case of concrete mixed with scale waste, an addition of over 25% brought about a reduction in compressive strength.
