Crusher dust is made from recycled crushed rock or concrete, which is 5 millimetres or smaller in size. It contains fine particles such as soft sand, making it a valuable packing material. It is a by-product of concrete recycling; it has strong compaction abilities to create a smoother finish between pavers.
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.

For M20 grade, 25% is the optimum percentage of stone dust mix with the concrete. 30% of stone dust requires relative high cement content. If 50% replacement of sand 450 kg per meter cube cement needed to achieve the target means strength for M25 grade.
Roller Compacted Concrete (RCC) is experiencing rapid growth in its usage all over the world. Thus, it is crucial to examine the characteristics of RCC. This research work investigates the durability studies of RCC with sodium bentonite as a special admixture and fine aggregate as crusher dust. Three different groups of concrete mixes are considered in this …

Crusher dust is made from small particles of recycled crushed rock or concrete & is commonly used as a cost-effective filling & packing material around any areas that require compaction. ADDRESS: 18 Kerryl Street, Kunda Park. OPEN …
As crusher dust often contains recycled concrete, it is especially useful for creating strong smooth surfaces beneath slabs, pads, and pavers. It is a non-porous material that stops water seeping in below surface structures, slabs, …
When we talk about workability then dust concrete has low workability as compared to no dust concrete. ... the disposal of stone dust generated from stone crusher is becoming a problem. ... (0% sand replacement level) for the concrete mix-ratio 1: 1.5: 3. cubes to study the strength of concrete made of crushed rock material, and the results ...
Crusher run is typically used underneath concrete slabs, patios, driveways, sidewalks, and walkways and ranges in sizes from ½" to 4" with stone dust. How Much Crusher Run Do You Need? Crusher run is ordered by the ton. Since crusher run weights approximately 2,500 lb. per cubic yard, first determine the volume requirement of your project.
The Concrete Mix Ratio. The basic concrete mix formula is typically represented by the ratio: ( text{Concrete Mix} = text{Cement} : text{Sand} : text{Aggregate} ) Common mix ratios include: 1:2:3: A general-purpose mix for projects like sidewalks and slabs, where one part cement is mixed with two parts sand and three parts aggregate.
The usage of plentiful raw discarded resources in the manufacturing of concrete has proven to be a sustainable and environmentally beneficial method of making concrete for a variety of purposes. In this study, the physical and mechanical properties of concrete made by partially and fully substituting fine aggregates and ordinary Portland cement with periwinkle shell ash …
Figure 5:Variation of compressive strength of M25 grade concrete with different proportions of % crusher dust at 28 days. From the curves, it can be observed that replacement of crusher dust has shown more compressive strength than normal concrete and 50% crusher dust concrete. It can also be observed that
One of the best mixture ratios for a concrete slab is 1 : 3 : 3 (cement : sand : stone), this will produce approximately a 3000 psi concrete mix. This mixing ratio is excellent for a shed slab, but it's also good for most concrete patios, footings, steps, and foundation walls.
