Comparison of The Effect of Steel Slag Usage As a Fine Aggregate Against Compressive Strength And Flexture on Reinforced Concrete With Normal Concrete (Experimental Study)

One key element in that development is concrete. The basic ingredients of concrete is a mixture of cement, water, fine aggregate and coarse aggregate, while the concrete using steel reinforcement called reinforced concrete. The times in the era of rapid globalization have resulted in increasing number of second-hand goods / waste can be a problem for the existence of life, one of which is the existence of waste steel slag. To that end, much has been done in order to recycle in order to overcome the problem of the existence of this waste. One way is to capitalize upon such waste for purposes that could be used. In this study, the steel slag is used as a substitute or substitutes in normal concrete mix. Variations addition of steel slag at normal concrete to determine the compressive strength and flexural strength better and is expected to improve the quality of the concrete form of the compressive strength and strong bending. The variation of the addition of steel slag used was 0%, 15%, 25%, and the testing was done by the compressive strength and flexural strength. From the test results obtained by the resulting increase in the value of the slump, the increase in the compressive strength and increased compressive strength lentur. The increase in the capacity of steel slag respectively 11.91% and 20.35%, of normal concrete. Whereas the increase in the flexural strength of steel slag substitution respectively 16.62% and 31.18% of normal concrete. Therefore, if conducted further research it is better grades of steel slag enlarged variation of more than 25% in order to be used as a substitute. Continued research for high quality concrete can be done by mixing a solution that can increase the holding capacity of steel slag with other concrete constituent materials.
