Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of up to 80% Copper slag as replacement of fine aggregate (sand), and can be effectively used in structura Also as percentage of Copper Slag increased the density of concrete increased. ...

Therefore concrete will continue to be the construction material in the foreseeable. There is need to improve its properties like workability, strength and durability of concrete. The research has been executed in order to utilize smaller quantities of cement and aggregates, also conserve our natural...
This manuscript presents a review of the potential and challenge of using recycled concrete aggregate (RCA) as the substitute for natural aggregate (NA) in concrete mixtures. Using RCA in concrete preserves the environment by reducing the need for opening new aggregate quarries and decreases the amo...
Concrete properties are usually worsened by the use of high percentages of recycled aggregates of concrete. This paper addresses the efficiency of using recycled concrete as an aggregate by systematically presenting results on the influence of silica fume on recycled aggregate concrete (RAC) properties...

In this study, emphasis is given on the different types of gradation of aggregates and their influence on the properties of concrete. Standard grading curves as proposed by Gambhir, 2004 are studied in detail to understand the behavior of coarse and fine aggregates. Gap grading is a relatively...
