Abstract

: As the times develop portland cement became a very important material and it widely used to build various infrastrcture. However the process of making cement would cause a big problem which is releasing carbon dioxide (Co2) into the atmosphere freely which resulting in the depletion of the ozone layer. Geopolymer mortar was a mixture of which the basic material did not use the portland cement as a binder. Did to find out the effect of the use of geopolymer marls a study was conducted using experimental methods. The purpose of this study was to determine the effect of NaOH contentration strength of marl geopolymer mortar. Cube specimens measurring 5 x 5 x 5 cm3 with molarity variations 8M,10M, 12M, 14M, and 16M as many as 75 specimens. Mortar curing by drying it at room temperture, at ages 3, 7, 14, 21, and 28 day. From the results of the research, the maximum density of geopolymer mortar was obtained at the age of 28 day using a 16M activator ratio of 2,30 grams, and the maximum compressiv strenght value of geopolymer at 28 days using a 16 M activator ratio was 8,13 Mpa. It could be conclouded that the higher molarity was used in the mixture then the mor OH- was presesnt in the mixture so that the process the bind ing would go much faster.

Abstract

Penelitian ini membahas mengenai pemanfaatan abu cangkang sawit sebagai bahan penyusun mortar geopolimer bertujuan mengetahui pengaruh konsentrasi rasio NaOH terhadap kuat tekan mortar geopolimer abu cangkang sawit. Abu cangkang sawit digunakan sebagai prekursor karena mengandung alumina dan silika yang dapat bereaksi membentuk bahan semen dan mengunakan aktivator sebagai pengikat seperti, NaOH (natrium hidroksida) dan Na2SiO3 (natrium silikat). Metode yang digunakan-dalam-penelitian ini-adalah metode eksperimen yaitu melakukan pengujian langsung di-laboratorium. Rasio aktivator Na₂SiO₃ : NaOH yang digunakan pada penelitian ini adalah 1:2 dan konsentrasi yang digunakan adalah 8 M,10 M, 12 M, 14 M, dan 16 M. kuat tekan maksimum adalah pada umur 28 hari dengan komposisi rasio perbandingan Na2SiO3 : NaOH, 1:2 sebesar 15,74 Mpa. Semakin besar molaritas yang digunakan maka kuat tekan-mortar-geopolimer akan_semakin meningkat
