Analysis Of Concrete By Partial Replacement Of Coarse Aggregate With Crumb Rubber

Y.Suma, Challa.Nithin kumar Reddy

The principle point of the investigation is to distinguish the utilization of reused material in the concrete as it upgrades the mechanical properties of cement. As "Crumb Rubber" is likewise one of the strong waste which can be utilized as a part of cement by somewhat supplanting fine aggregate. In this investigation "Crumb Rubber" was supplanted by volume of coarse total as 0% to 20% volume of "Crumb Rubber" supplanted coarse aggregates at an interval of 5% increase. Numerous tests were done for fresh concrete (i.e. Slump test, Flow test, Compaction factor etc.) and for hard concrete (i.e. Compressive strength). The elastic properties are also determined from concrete cubes. 3 cubes for each percentage of replacement are casted and tested after 28th days of curing. This attempt of replacing the coarse aggregates with rubber aggregates will save the natural aggregates, reduces weight of structure and also helps achieve sustainability.
