Using waste concrete as aggregate - ScienceDirect

1995-10-1  As the percentage of waste concrete in the mixture increases, there occurs some decreases in workability. In C 16 concretes, 20 % incre- ase of waste concrete decreases the density 1.7 % and this is 0.8 % in C 20 concretes. Each 20 % increase in waste aggregate causes a decrease of 3.85 % in Schmidt hardness values.
