Abstract :
country of Indonesia is a population that is densely populated with the demand for housing or settlement development increasingly increase. For this construction requires concrete because concrete is very important. Concrete constituent material consists of hydraulic cement (Portland cement), coarse aggregate, fine aggregate, water and added material (admixture or additive). At present concrete is interpreted as having wide use and developed into environmentally friendly concrete by utilizing the waste that is around us for alternatives to normal aggregate substitute materials. One example of waste that can be used is waste from bore piles. In this study, bore pile waste was added to the concrete mixture by 5%, 10%, 15%, and 20% of the weight of the gravel, with a testing time of 7 days, 14 days and 28 days. Testing is carried out with two stages of research. The first stage is material testing and the second stage is testing the specimen, namely the compressive strength and tensile strength of the concrete. Based on the results of testing the compressive strength and split strength of the concrete the optimum percentage value of addition of bore pile there is a variation of 15% with a compressive strength at 28 days of age of 28,497 MPa and a concrete split tensile strength of 2,476 MPa. These results indicate that the use of piled waste bore ingredients with 15% levels in concrete mixtures can increase the compressive strength and split tensile strength in K 300 concrete quality.
