Abstract

Purpose in this research is to analyze the influence of the quality of co ncrete by the addition of substance added fly ash and compared with concrete normal ( without more fly ash ).Variation fly ash to substitute cement used is of 0 %, 7 %, 9 %, 11 %, 13 %, and 15 %, sample made is about 18 sample that is 12 sample the age of 1 days and 6 sample the age of concrete 28hari.Based on the results of analysis and testing the results. At the age of one day result strong press or on the fly ash 0 % namely 15,287 MPa, the result of the fly ash 7 % stronger result strong complained bitterly compared with concrete normal ( without the use fly ash the 15,994 MPa. On the fly ash 9 % obtained an increase of 18,401 MPa and the fly ash 11 % receive is 19,250 MPa, while in the fly ash 13 % and 15 % decline is as much as 15,287 MPa and 15,853 MPa, thus result strong press with use fly ash deficient in the 9 % to 11 %, because strong complained bitterly higher than concrete normal or no use fly ash. At the age of 28 days result strong press or on the concrete normal (without the use fly ash) have increased, strong press concrete normal obtained to beyond strong press plan is as much as 31,706 MPa. On the fly ash 7 % obtained result higher than concrete normal is as much as 30,007 MPa , while in the fly ash 9 % , 11 % , 13 , and 15 % has been an increase in result strong press of 36,235 MPa , 31,706 MPa , 35,103 MPa and 28,309 MPa on the fly ash 7 % and 15 % at the age of 28 days compared with concrete normal ( without the use fly ash ) the difference too small , so obtained the optimal at the age of 28 days was 9 % to 13 % of the weight of a cement.
