Abstract

Penelitian ini menggambarkan beberapa usaha dalam memanfaatkan material pozolan alami yaitu trass sebagai pengganti semen. Trass pasuruan mempunyai komposisi yang mirip dengan fly ash, tetapi senyawanya tidak bersifat amorf. Trass pasuruan hanya dapat dijadikan sebagai bahan pengisi atau filler dalam pembuatan beton geopolimer yang berbahan dasar fly ash dan diaktifkan oleh aktifator alkalin berupa larutan sodium hidroksida. Hasil pengujian menunjukkan bahwa kekuatan tekan binder dan beton geopolimer sangat dipengaruhi oleh molaritas larutan sodium hidroksida juga perbandingan aktifator yang digunakan. Pada binder yang memiliki molaritas larutan sodium hidroksida 8 molar, kuat tekan tertinggi dimiliki oleh binder yang memiliki perbandingan aktifator 2,5. akan tetapi pada beton terdapat sedikit perbedaan. Kuat tekan hidroksida 8 molar tertinggi dimiliki oleh beton yang memiliki perbandingan aktifator 2. Sedang pada beton dan binder yang bermolaritas larutan sodium hidroksida 10 molar kuat tekan tertinggi dimiliki oleh beton dan binder yang memiliki perbandingan aktifator 2,5. Pengikatan, porositas serta kuat tarik memiliki pola seperti beton bermolaritas sodium waktu halnya pola yang terjadi pada kuat tekan beton. Analisa perbandingan dengan beton konvensional menunjukkan bahwa trass memiliki sifat mekanis yang lebih baik pada beton semen

This research describes several efforts to utilize natural pozzolan material, namely trass, as a substitute for cement. Pasuruan trass has a composition similar to fly ash, but the compound is not amorphous. Pasuruan trass can only be used as a filler in making geopolymer concrete which is made from fly ash and is activated by an alkaline activator in the form of sodium hydroxide solution. The test results show that the compressive strength of the binder and geopolymer concrete is greatly influenced by the molarity of the sodium hydroxide solution as well as the ratio of the activator used. In a binder that has a sodium hydroxide solution molarity of 8 molar, the highest compressive strength is possessed by a binder that has an activator ratio of 2.5. However, in concrete there are slight differences. The highest compressive strength of 8 molar hydroxide is possessed by concrete which has an activator ratio of 2. Meanwhile, in concrete and binder which has a sodium hydroxide solution molarity of 10 molar, the highest compressive strength is possessed by concrete and binder which has an activator ratio of 2.5. Bonding, porosity and tensile strength have a pattern similar to that of sodium molarity concrete over time, as well as the pattern that occurs in compressive strength of concrete. Comparative analysis with conventional concrete shows that trass has better mechanical properties than cement concrete
