The concrete ratio is usually calculated differently depending on where and what we will use the concrete for. The so-called classic ratio for cement mix is called the 1-2-3 concrete-mix. This means that the ratio is supposed to be made from 1 part cement powder, 2 parts sand, and 3 parts washed aggregate.
Crusher dust or stone dust is a compactable, economical packing material used for stabilising surfaces. Crusher dust is also known as blue metal, cracker, or rock dust. ... It can be used as a base layer under concrete slabs, water tanks, piping, and anything paved, as this material is the perfect compact filler. Types of Crusher Dust.

cement ratio was found out by conducting slump test for a constant slump of 60 mm. Tests were conducted in limited ratios of sand: quarry dust choosing one ratio each above and below the one giving maximum strength say 60:40, 50:50 and 40:60. At the age of 28 days the compressive strength, tensile strength and flexural strength were determined.
Crushed dust is also used as a concrete aggregate and concrete substitute when creating pathways and subways. This concrete does break, prevents water from clogging, and creates an aesthetically pleasing surface to fit the client's perspective. ... The recommended ratio of cement to crusher dust varies depending on the specific application ...

The reduction is 12 to 1, like an impact crusher, but with minimal wear and dust, unlike an impact crusher. Concrete Shredders are best used as primary shredders as the finished material is approximately 3" minus.
Rainfall can severely affect concrete proportioning, leading to an imbalance in the water-cement ratio and ultimately affecting the strength and durability of the concrete. In addition, precipitation during construction can also inconvenience the operation of the mixing plant, increasing production costs and difficulties.
