Substitusi Material Pozolan Terhadap Semen pada Kinerja Campuran Semen

Joice Elfrida Waani, Lintong Elisabeth

Abstract


Abstrak

Penggunaan material semen dalam industri konstruksi terus meningkat dari tahun ke tahun dan peningkatan ini berakibat pada meningkatnya produksi gas buangan, co2 dialam yang berakibat pada pembentukan efek rumah kaca. Dalam rangka mengeliminasi pengaruh buruk terhadap lingkungan yang diakibatkan oleh teknologi maupun penggunaan material yang tidak ramah lingkungan, para ahli dibidang rekayasa konstruksi terus berupaya untuk menemukan teknologi dan material alternatif yang dapat menghasilkan material konstruksi yang ramah lingkungan tanpa mengurangi kinerja strukturalnya. Penggunaan teknologi daur ulang perkerasan jalan dengan penambahan material alternatif pengganti semen pada konstruksi perkerasan jalan, merupakan upaya positif dalam rangka mendorong penggunaan teknologi dan material yang ramah lingkungan dibidang konstruksi bangunan teknik sipil. Material pozolan yang berupa material hasil buangan industri batu bara maupun bahan pertanian atau material pozolan alam adalah material yang dapat digunakan sebagai bahan pengganti semen karena sifatnya yang menyerupai semen jika ditambahkan pada campuran semen. Penggunaan material ini sebagai material pengganti atau substitusi semen dalam campuran beton menunjukkan peningkatan workabilitas dan kinerja campuran baik pada campuran beton mutu tinggi maupun pada campuran semen dengan kekuatan rendah (low strength materials). Artikel ini membahas tentang beberapa hasil penelitian terhadap campuran beton/semen yang sebagian semennya disubstitusi dengan material pozolan yang menunjukkan berbagai keunggulan dari campuran tersebut untuk dapat diaplikasikan sebagai material konstruksi, baik pada campuran beton bermutu tinggi maupun campuran semen dengan kekuatan rendah.

Abstract

The use of cement material in the construction industry increase continuously from year to year and this increase results in increased production of exhaust gases, co2 in nature which resulted in the formation of the greenhouse effect. In order to eliminate the adverse influence on the environment caused by technology and the use of environmentally unfriendly materials, experts in the field of construction engineering continues the efforts to find technologies and alternative materials that can produce environmentally friendly construction material without reducing its structural performance. The use of recycled technology in pavement contruction with alternative materials as cement replacement is a positive effort in order to encourage the use of technologies and environmentally friendly materials in engineering construction. Pozzolanic material in the form of material waste product of the coal industry and agricultural materials or natural pozzolan material is a material that can be used as a cement replacement material because it is resembles a cement when added to the cement mixture. The use of this material as a material replacement or substitution of cement in the concrete mixture showed increased workability and performance either of high quality concrete or low strength materials. This article discusses some of the results of research on the cement mixture with the cement partially substituted by means of pozzolanic material showing the superiority of the mixture to be applied as a construction material, either in a mixture of highquality concrete or cement mixture with a low strength.
