Mountains of mining waste from all over the world are waiting to be resurrected as concrete construction material. New research at DTU Civil Engineering shows that up to 10 per cent of the cement in concrete can be replaced by mine tailings, which are the remnants of crushed ore after extraction of metals and substances.

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.

Crushed gravel is an aggregate frequently used in construction. The stone and aggregate industry creates crushed aggregate using a lengthy process. The stone must be mined in a quarry and then transported to the rock crusher, which begins the process of crushing the larger stones into more manageable pieces.

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

When landfills located near populated areas started refusing broken concrete in the 1970s, the construction industry started crushing it to make aggregate for use as compactible fill. Wood and steel reinforcement were separated out, leaving aggregate that often included a mixture of concrete, brick, and asphalt, along with some dirt.
