THE SPIRIT OF SOCIETY JOURNAL : International Journal of Society Development and EngagementTHE SPIRIT OF SOCIETY JOURNAL : International Journal of Society Development and EngagementConcrete is a significant and most dominant material used in building structures. Concrete consists of a mixture of cement, aggregate, water, and added ingredients. Concrete is a material that has an essential role in making concrete because it can change the real properties to suit the needs. Asbestos is a concrete-added material that can reduce the use of cement and produce concrete with absolute consistency. The purpose of this study was to determine the effect of adding asbestos waste to cement. The method used is an experimental method based on previous research. The specimen used was cylindrical with a diameter of 15 cm and a height of 30 cm. The percentage variation of asbestos waste addition is 0%, 50%, and 100% of the weight of cement used. Typical concrete test results obtained an average value of 22.08 MPa, a 50% percentage produces an average compressive strength of 21.32 MPa, and a portion of 100% provides a compressive strength of 22.93 MPa. Then the results of the actual strength test have increased in the percentage of asbestos waste 100%.
Based on the research conducted, it can be concluded that the slump value of standard concrete is 6 cm, while the concrete mixtures with 50% and 100% asbestos waste have slump values of 4 cm and 3 cm, respectively.The compressive strength of standard concrete at 28 days is 22.The addition of 50% asbestos waste results in a compressive strength of 21.32 MPa, and the addition of 100% asbestos waste yields a compressive strength of 22.Therefore, the addition of 100% asbestos waste can slightly increase the compressive strength of concrete.
Penelitian lebih lanjut dapat dilakukan untuk menguji pengaruh variasi ukuran serat asbestos terhadap kekuatan tarik beton. Hal ini penting karena kekuatan tarik seringkali menjadi faktor penentu dalam desain struktur beton. Selain itu, studi komprehensif mengenai durabilitas beton dengan campuran asbestos, termasuk ketahanannya terhadap serangan sulfat dan klorida, perlu dilakukan untuk memastikan keamanan dan umur layanan struktur beton yang menggunakan material ini. Terakhir, penelitian tentang potensi pemanfaatan jenis limbah asbestos lain selain yang digunakan dalam studi ini, serta optimasi proporsi campuran untuk mencapai kinerja beton yang optimal secara ekonomi dan lingkungan, dapat memberikan kontribusi signifikan dalam pengembangan material konstruksi berkelanjutan. Penelitian-penelitian ini diharapkan dapat memberikan pemahaman yang lebih mendalam tentang potensi dan batasan penggunaan limbah asbestos dalam industri konstruksi, serta mendorong inovasi dalam pengembangan material beton yang lebih ramah lingkungan dan efisien.
