The influence of aggregate gradation on workability of the mix is of concern because of its effect on the finished block properties and it further effect on the speed of production. An excess of fine-fines (crusher dust) in some aggregate will frequently produce a sticky mix which is slow in feeding into the mold box while a harsh mix will

This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and by mass of aggregates.
