Effects of Recycled Aggregates on Water-Cement Ratio for

Abstract: Two classification methods for coarse recycled aggregate used in asphalt concrete were investigated in this paper, respectively classifying by coarse recycled aggregate properties and asphalt concrete properties. When classifying by coarse recyc

Steam-cured recycled aggregate concrete incorporating

The objective was to (i) determine the feasibility of MESC in recycled aggregate concrete (RAC), (ii) determine the optimum steam curing conditions (curing duration, maximum temperature, and duration of holding maximum temperature), and (iii) evaluate the

Re-Use of Polypropylene Fiber Admixed Recycled Aggregates in

Recycled aggregates’ specific weight and unit weight were calculated. Values of specific weight and unit weight were decreased. By using fiber-reinforced recycled aggregates a new concrete mixture was made. To the new mixture, recycled aggregates with siz
