What are the Correct Concrete Mixing Ratios
Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need. a good mixture for concrete has 4 basic ingredients. To make concrete there are four basic materials you need:

What is Concrete Sand?
Concrete sand is a label that is typically used to describe the coarse washed sand that is a common ingredient in cement and asphalt mixtures. Its grains are larger than those of masonry sand, but a processing and screening process ensures that there are no large rocks or pebbles present. This material is often made of things like gneiss ...

Nickel Slag
Journal of the Transportation Research Board, 2(2208), 1–8. Granulated nickel slag is essentially an angular, black, glassy slag "sand" with most particles in the size range of − 2 mm (No. 10 sieve) to + 0.150 mm (No. 100 sieve). It is more porous, with lower specific gravity and higher absorption, than air-cooled nicked slag.

The use of BOF slag powder as supplementary cementitious material directly impacts the compressive strength of concrete (Wang et al., 2013a, 2013b). In Fig. 4, the strength of concrete is shown to decrease as the substitution ratio of BOF slag increases, especially at a high water-to-binder (W/B) ratio of 0.5 (Wang et al., 2013a).
