چکیده
Due to expansion in infrastructure and increased development of urbanization Ethiopia, most the places are covered either by impermeable cement concrete or bitumen that blocks percolation water from rainfall. A porous made zero fine aggregates, creating a pore permits be permeable, is highly desirable. Similarly, demand for natural coarse aggregates remains high, while resources being depleted. Therefore, this study aims investigate properties using recycled aggregate as partial replacement aggregate. Experimental tests were conducted on setting time, workability concrete, compressive, split tensile, porosity, permeability concrete. The at different ratios—0, 15, 30, 45 60%—revealed RCA suitable use optimum percentage terms strength 30%, with 28th-day compressive 17.37 MPa. However, slight increments observed porosity coefficient. produced structural which walkways other flat works, whereby heavy vehicle traffic loads do not exist.

Performance of High-strength Concrete Made with Recycled Ceramic Aggregates
Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...

Self-compacting concrete is a new high performance concrete with high ductility and segregation resistance. In recent years, construction material manufacturers have focused their attention on lightweight concrete and have strived to use lightweight concrete, if possible, in load-bearing parts of buildings. Concrete with both self-compacting and lightweight properties is favourable in this cont...

متن کاملDrying shrinkage of concrete made from recycled concrete aggregate
Recycled concrete aggregates (RCA) are used in new concrete mixes, termed recycled aggregate concrete (RAC). Among losses in most fresh and hardened properties, literature reports that RAC suffers increased levels of drying shrinkage compared to equivalent mixes incorporating conventional aggregates. This paper describes the procedure and results of a range of experiments conducted on a commerc...
