The influence of stone crushing processes on aggregate ...

Aggregate shape properties have a direct influence on the behaviour of pavement materials. The crushing process is the main factor responsible for generating these shape properties; however, there has hardly been any effort directed toward optimising the performance of pavement materials by altering the crushing techniques to produce aggregate particles with desired shape properties.

 · Mutations occur when there is a change in the codon of amino acids in the DNA. In many cases, the mutation is silent or slightly harmful. Silent mutations have no effect on the DNA sequence or phenotype. This occurs because if the change is with the third codon there is no change with the amino acid and genetic code.

Recycled Concrete Aggregate Research Papers

The recycling consists of crushing old concrete into aggregates, and then processing it into new mixture using recycled aggregates with specified sizes [3,4]. The aim of this recycling is to save nature from deforestation and dryness, by reducing the need to gravel and so the quarries work, and also to economize the waste management [5,6].
