| description | In current state of the World, the pollution is increasing very fast. One of its major reason is the production of huge quantity of cement which causes outflow of CO2 into the environment and land dumping of construction and demolition waste which leads to the land pollution. In order to address this major issue, it is important to decrease the utilization of cement by substituting the cement with by product such as slag and using recycled aggregates as a replacement of natural aggregates. This research aimed to utilize evaluate the performance of sustainable high-performance concrete reinforced with steel fibers which is produced with recycled aggregate. Crushed stone aggregates are supplanted with recycled aggregates extracted from source concrete that had compression strength of 45 MPa and 85 MPa at proportions of 50% and 100%. Steel fibers are used at 2% to produce high-performance concrete, and in a few of the mixtures, the cement was substituted with granulated blast furnace slag. In addition to mechanical performance, the durability properties, i.e., electrical resistivity, drying shrinkage, and water absorption, of concrete blends were examined. The test outcomes show that high-performance concrete with the required characteristics can be developed utilizing recycled aggregates extracted from source concrete of high strength. The inclusion of double hooked end steel fibers considerably improves the mechanical characteristics of RAC. Concrete formed with high-quality recycled concrete aggregates and mixes comprising granulated blast furnace slag (GBFS) and double hooked end (DHE) steel fibers shows decreased drying shrinkage and water absorption in comparison to normal concrete. The outcomes of the present study assist in making of suitable high-performance concrete which is sustainable and budget friendly. |
