    30/07/2017  For instance, crushing strength of aggregates decreased from 1.56 N/mm 2 to 1.27 N/mm 2, which was about 20% decrease in crushing strength. Further increase in the content of CF continuously reduced the crushing strength. This was probably attributed to the agglomeration of CF at a high dosage that could lead a higher porosity in aggregate. The crushing strength
