The 100 recycled aggregate mixture Mixture 2 did not perform as well as expected This mixture was the second lowest strength producer second only to the 100 recycled mixture Mixture 3 This indicates that there may be something happening between the PC and the aggregate which would cause this decrease in strength

However there is a limitation for the replacement content of natural fine aggregates by fine recycled aggregates in the mixture that is directly associated with the negative effect on the properties of concretes and mortars

Only up to 10 to 20 percent fine RCA is beneficial The aggregate should be tested at several substitution rates to determine the optimal rate Often recycled aggregate is combined with aggregate when used in new concrete An example of a mix design using recycled aggregates in a pavement application is shown following table

In this study recycled glass is used to replace the natural fine aggregate in different mix proportions to obtain the optimum combination that will produce the highest strength The control samples are Grade 30 ordinary Portland cement concrete OPCC containing 100 natural sand and coarse aggregate The recycled glass concretes contain 70 natural fine aggregate 30 size 300 micron
