It can be used “as is” for bulk fill / drainage / etc. When cleaned, crushed, and graded for size, it can be used as a base underneath a new concrete pour. Recycled concrete can also be used as aggregate within the new concrete.

- Move the Concrete Chunks With a Hand Truck.
What can you use old concrete for?
Old, unneeded concrete can be recycled and used to create recycled aggregate. In most cases, recycled aggregate will be used as a subbase material, but it can also be paired with virgin materials and reused as an aggregate in new concrete.
What is concrete gravel?
Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel.
What is stone dust used for?
Stone dust is a byproduct of crushing stone. Although it was originally a waste product, it is now used for agricultural and hardscaping purposes. Most commonly, stone dust is used for paving projects such as driveways, patios, and pathways.
Can you grind up concrete and reuse it?
Fortunately, concrete can be recycled and reused in many ways. Typically (but not always) the process involves crushing or pulverizing the concrete rubble near the demolition or building site. Choosing the best method often depends on the size and shape of the concrete pieces to be recycled.
What can I do with old concrete slabs?
Another alternative to throwing concrete away is to recycle it. Companies that work in the building materials sector will often take old concrete and turn it into recycled aggregate. It can then be used as a subbase material or as an aggregate in new concrete.
What happens when stone dust gets wet?
Stone dust is a fine material that absorbs moisture readily, then releases it slowly. The same properties that work wonders for organic gardening can wreak havoc underneath pavers, causing efflorescence and allowing them to settle or shift easily under load.
Is stone dust better than sand?
Which is Better: Sand or Stone Dust? Sand is ultimately a much safer option than stone dust for paving projects. However, this is not a black-or-white issue. You may choose to use stone dust if you have a large supply of it, or prefer the texture and appearance of it.
What is stone powder?
Stone powder cement (SPC) is widely used as a novel cement substitute material in concrete for its good gelling performance and low cost.
What is soft stone powder?
It is often used to improve the quality of the surfaces by offering them resistance against electricity, chemical and thermal. Offered product is also used in number of industrial sectors varying from construction to chemical which serves several purification and refining purposes.
What is soap stone powder?
Talc or Soapstone or Steatite is an alteration product of original or secondary Magnesium minerals. Talc is hydrous Magnesium Silicate and its chemical composition would correspond to 63.5% Silica (Si02), 31.7% Magnesia (MgO) and 4.8% water (H20).
Can you mix cement with stone dust?
yes, the use of stone dust in cement increases the compressive strength. Because it fills all the pores and fine voids, which make the concrete void-free and increase the flexural strength. But if the use of stone dust above the limit decreases the compressive strength and workability.
How do you mix cement sand and gravel?
Another “old rule of thumb” for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable. This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability.
How do you compact crusher dust without a compactor?
We recommend you use a mini loader with a bucket to move large amounts of crusher dust around your job site. If you have the option, use a levelling bar attachment to quickly and evenly spread the material around. Again wet it.
Can you use crusher dust concrete?
Compacting material such as crusher dust can be used for multiple projects including creating a smooth surface between cement pavers, driveways, yard garden pathways, gaps between paving and stone, and more.
Is crusher dust the same as rock dust?
Crusher dust, also known as blue metal, cracker, or rock dust, is simply the material leftover when making crushed rock. As rocks are run through the crusher, tiny pieces and dust particles are left behind.
