Recycling crushed concrete to be reused helps reduce landfill crowding AND saves more resources from being used to create new concrete. Old concrete can be crushed down to specific sizes, cleaned so that unwanted debris is removed from the mixture, and reused as a solution to a number of construction and landscaping problems.

Soda-lime glass used for bottles was washed and crushed to fine and coarse aggregate sizes for use in the concrete mixes. Samples were cured under 95% RH at room temperatures (20–22 °C), heated in the oven to the desired temperatures, allowed to cool to ambient temperatures, and then tested for their residual compressive strength.
Concrete is a mixture of cement, water, and aggregate material. Portland cement is made by heating a mixture of limestone and . clay containing oxides of calcium, aluminum, silicon and other metals in a kiln and then pulverizing the resulting clinker. The fine aggregate particles are usually sand. Coarse aggregate is generally gravel or crushed ...

For example, if the grading of two crushed fines (≤ 0.125 mm) coming from the same deposit is altered by classification (washing, in this case) and this is the only variable between two concrete mixes (i.e. the total fines content is kept constant), this can have a tremendous effect on the concrete slump-flow value (see below).
Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve. Effects of dust content in aggregate on properties of fresh and hardened concrete are not known very well. An experimental study was undertaken to find out the ...
Retaining Walls. Layering crushed concrete is also a great way to create a retaining wall and control erosion on slopes or hills in your yard. Different sizes of crushed concrete can function together to help prevent erosion. A layer of smaller, more broken-up crushed concrete …
Experimental Plan In this work, 5%, 10%, 15%,20% and30% of fine aggregate is replaced by glass powder for M20 grade concrete. Cube specimens of size 150 mm x 150 mm x 150 mm were casted for different proportions with glass powder and compared with the properties of concrete prepared without glass powder (control mix). Compression test was ...
Abstract: This paper presents an assessment of the strength properties of concrete containing crushed cow bone (CCB) as partial or full replacement of fine aggregates. Fine aggregate was replaced with CCB by weight up to 100 % at intervals of 10%. The properties investigated were: workability, density and the compressive strength.
Crushed Concrete Fines. Crushed concrete fines are an eco-friendly material that is not only economical in price, but can also be used in a variety of landscaping projects.

Recycled crushed concrete begins by breaking down original structures. This can include just about any of the normal concrete structures that would go into landfills, like building slabs, curbs, foundation, and any sort of concrete structure. The breakdown begins by using industrial crushing equipment to demolish the existing structure.

Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
