“…The densities can not be classified as lightweight mortar, it is caused by the void of the specimen as the result of aluminium powder as a foaming agent. The assumption strengthened with the densities of fine ALWA in the previous study by Perdanawati, et al[16]. The data demonstrated that the densities of fine ALWA FA-0-1050-6 was 1070,06 kg/m3 and FA-50-1050-6 was 968,15 kg/m3, both fine ALWA classified as lightweight aggregate based on ASTM C-330.…”

“…The previous study by Perdanawati, et al [16], fine ALWA made with three compositions that were Lusi mud: fly ash = 100%:0; 70%:30%; 50%:50%. The composition was sintered at two temperatures (1000°C and 1050°C) for 4 and 6 hours.…”

“…Figure 3 shows the X-Ray diffraction result of M-0 that was made by FA-0-1050-6. Based on previous research by Perdanawati, et al [16], fine ALWA that is made from fly ash has chemical compounds SiO2, Fe2O3, Al2SiO2 that are classified as pozzolanic material based on ASTM C-618. Xray.…”

“…AAC made from fine ALWA from Lusi mud and Fly Ash as a filler, sintered Lusi mud as the binder, aluminium powder as the foaming agent and cure with an autoclave at 14 bars for 6 hours. Fine ALWA made from Lusi mud mixed by fly ash investigated in previous research by Perdanawati, Triwulan, & Ekaputri [16]. Binder consists of Lusi mud sintered at 800°C, Original Portland Cement (OPC) and Ca(OH)2.…”

This paper presents the results of an experimental study on Autoclaved Aerated Concrete (AAC) containing Sidoarjo Mud (Lusi) mud to utilize the mud. Autoclaved aerated concrete (AAC) made from fine Artificial Lightweight Aggregate from Lusi mud and Fly Ash as a filler, sintered Lusi mud as the binder, aluminium powder as the foaming agent. Autoclaving process was conducted at 14 bars for 6 hours. AAC prepared in 3 (three) compositions, based on the variation of filler. The filler used in the research were sands (M-sand), fine ALWA made from Lusi mud (M-0), and fine ALWA made from Lusi mud mixed by fly ash (M-50). The workability of AAC investigated in this research was compressive strength of the AAC after 14 days, density, and X-Ray Diffraction. Experimental data showing that the compressive strength of AAC depends on the filler that is used, AAC classified at AAC-3 and AAC-4. The density of all the AAC can’t be classified as lightweight concrete. Experiment data showed the density occurs at 1148,0 kg/m3 to 1206,4 kg/m3. Chemical compounds of AAC with fine ALWA filler consisted of quartz, hematite, tobermorite, calcite, anorthite, magnetite, lime, and forsterite.
