Abstract

Along with the increasing advancement in technology development of a region, resulting in further increase the use of cement as a base for such development. Therefore, the need for an alternative to cement as a base for development. In this thesis the author uses abu sekam padi as a cement substitute, abu sekam padi contains pozzolan which is similar to cement. Abu sekam padi is used from rice mill in Pagar Alam. In this thesis the author reviewed the compressive strength of concrete with cement substitution using abu sekam padi, with variations in the composition of 10%, 11%, and 12% as well as a variation of 0% as control variables. Concrete compressive strength testing time starting from the age of 7 days, 14 days, 21 days and 28 days. From the results of testing the strength of concrete by using a variation of the composition of 0%, 10%, 11%, and 12% abu sekam padi obtained value of the compressive strength of each - each as follows: 344.44 kg / cm2, 317.04 kg / cm2, 239 , 26 kg / cm2, and 201.48 kg / cm2. From the test results obtained value of normal concrete cement water factor of 0,535; concrete with a mixture of 10% abu sekam padi of 0.63; a mixture of 11% abu sekam padi by 0.66; and with a mixture of 12% abu sekam padi 0,68. Based on the test results for the addition of 10% abu sekam padi reached the compressive strength of the plan is quality concrete K300 which enter the category concrete class III and can be used for structural construction, while 11% of abu sekam padi did not compressive strength of concrete plans K300 but remained concrete category class III and to the addition abu sekam padi of 12% decreased quality of concrete compressive strength did not reach the plan and get in on the concrete class II category.
