Abstract

Based on the results of research and discussion that has been described, it can be concluded into which are as follows : Age care greatly affect the strength of concrete, At the age of 28 days the compressive strength of concrete obtained at normal (without the use offlyash), Experiencing an increase, compressive strength of normal concrete compressive strength is obtained to exceed the plan that is equal to 28.875MPa. At the levels of fly ash 20% obtained higher scores than normal concrete in the amount of 47.369MPa, whereas the levels of fly ash 5%, 10%, and 15% also increased the compressive strength of 37.178MPa36.423MPaand32.838MPa respectively, at levels of fly ash 15% at 28 days compared with normal concrete (without the use of fly ash) the difference is too small, the importance of the optimal levels at 28 days was 5% - 20% of the weight of the cement and the high strength, so we conclude from this mix design that we should be careful when start mix all the component and follow the numbers that we got in the mix design.
