ABSTRAK Haqi Achmad Ubaidillah. 2017. Studi Eksperimental Kuat Lekat Pasangan Beton Ringan Aerasi (Autoclaved Aerated Concrete) dengan Variasi Ketebalan Thin Bed Mortar. Skripsi Jurusan Teknik Sipil Fakultas Teknik Universitas Negeri Malang. Pembimbing (I) Dr. Nindyawati S.T. M.T. (II) Drs. Ir. Sudomo M.MT. Kata Kunci Bata Ringan AAC Thin bed mortar Kuat Lekat Kekuatan dan kekakuan struktur dalam menahan gempa sangat bergantung pada sifat-sifat rangka struktur dinding pengisi dan kekakuan relatif kedua komponen tersebut. Keberadaan dinding pengisi memberikan kontribusi berupa kekakuan terhadap beban horizontal. Seiring perkembangan teknologi bahan bangunan dinding pengisi dapat disusun menggunakan bata ringan AAC. Ketebalan optimum thin bed mortar pada pasangan bata ringan yang berfungsi sebagai struktur masih memerlukan berbagai kajian salah satunya tentang daya lekat mortar. Selain itu pemasangan bata ringan di lapangan seringkali tidak simetris. Berkaitan dengan itu maka diperlukan penelitian untuk mengetahui nilai kuat lekat pasangan bata ringan dengan variasi ketebalan thin bed mortar dan panjang bidang lekatan serta mengetahui ada atau tidaknya interaksi antara kedua variabel tersebut. Penelitian ini merupakan penelitian eksperimen dengan variasi ketebalan thin bed mortar 2 mm 3 mm 4 mm dan variasi panjang bidang lekatan 1/3 bata (100 mm) 1/2 bata (150 mm) 2/3 bata (200 mm). Objek penelitian untuk pengujian kuat lekat menggunakan pasangan 3 bata ringan dan thin bed mortar dengan faktor air semen 0 25. Bata ringan AAC yang digunakan berukuran 300 100 50 mm. Jumlah keseluruhan benda uji sebanyak 45 dengan 5 benda uji untuk setiap kelompok variabel. Pengujian dilakukan menggunakan UTM (Universal Testing Machine) dengan beban 0 5 kN untuk setiap interval pembebanan hingga benda uji mengalami kehancuran. Hasil pengujian kuat lekat dianalisis dengan uji two-way ANOVA. Hasil penelitian menunjukkan bahwa tidak ada perbedaan rerata kuat lekat pasangan bata ringan dengan variasi ketebalan thin bed mortar secara signifikan. Nilai kuat lekat tertinggi terdapat pada benda uji dengan ketebalan thin bed mortar 3 mm pada panjang bidang lekatan 1/3 bata 1/2 bata dan 2/3 bata berturut-turut sebesar 0 432 MPa 0 361 MPa dan 0 284 MPa. Ada perbedaan yang signifikan pada rerata kuat lekat pasangan bata ringan dengan variasi panjang bidang lekatan. Tidak ada interaksi yang signifikan antara kedua variabel tersebut. Model keruntuhan pada bata ringan terjadi pada ketebalan thin bed mortar 3 mm. Secara keseluruhan dapat disimpulkan bahwa pasangan bata ringan dengan ketebalan thin bed mortar 3 mm mampu menahan gaya geser horizontal dibandingkan ketebalan 2 mm dan 4 mm. ABSTRACT Haqi Achmad Ubaidillah. 2017. Effect of Thin Bed Mortar Thickness to the Bond Strength of Autoclaved Aerated Concrete (AAC) Masonry Experimental Study. Undergraduate Thesis Department of Civil Engineering Faculty of Engineering State University of Malang. Supervisors (I) Dr. Nindyawati S.T. M.T. (II) Drs. Ir. Sudomo M.MT. Keywords Autoclaved Aerated Concrete Thin bed mortar Bond Strength Strength and rigidity of structures in resisting earthquakes depends on the properties of the structural frames walls and the relative stiffness of both components. The walls in building contributes to increase the resulting rigidity in withstanding the horizontal load. Along with the development of building material technology autoclaved aerated concrete (AAC) replaces brick as wall materials. Advanced studies in the influence of thin bed mortar thickness on ACC should be carried out to provide the optimum bond strength on masonry works. Researcher hence performs an experimental works to obtain the relation of thin bed mortar variation and the length of bonding area to the resulting bond strength and to conduct the interaction analysis of the aforementioned variables. Three different thickness of thin bed mortar which were 2 3 and 4 mm and three variations of bonding area representing part of brick length which were 1/3 and 2/3 were studied in laboratory testing. The AAC brick used was 300 100 50 mm. Testing samples consist of three pieces of AAC masonry layered in thin mortar bed. The mortar was prepared with water-to-cement factor (WCF) 0.25. Five specimens for each variable were prepared and were tested under compression test using Universal Testing Machine (UTM) with incremental loading of 0.5 kN. The samples were loaded until collapsed. The experimental data were then examined in two-way ANOVA analysis. The statistical analysis showed that there was no significant difference in terms of resulting bond strength as the increase of thin bed mortar thickness. In the other hand the bond strength of ACC masonry was highly influenced of bonding area. The greater the bonding length it increases the masonry capability to retain the subjected load. The highest bond strength was observed on the specimens using 3 mm of thin bed mortar with bonding length of the 1/3 1/2 and 2/3 of brick 0.432 0.361 and 0.284 MPa respectively. The interaction analysis presented a moderate relation between the tested variables. The model in AAC collapse occurred at a thickness of thin bed mortar 3 mm. Overall it can be concluded that the AAC masonry with thickness of thin bed mortar 3 mm are able to withstand the horizontal shear force compared to thickness of 2 mm and 4 mm.
