Abstract
Telah dilakukan fabrikasi bata ringan Aerated Autoclaved Concrete(AAC) dengan menggunakan variasi komposisi kandungan Si, Ca, Al dari bahan baku semen, pasir silika, kapur, air dan agent foam (pasta aluminium) sebagai bahan pengembang. Proses pembuatan rancangan variasi komposisi berdasarkan penelitian sebelumnya dengan menggunakan metode prediksi jaringan syaraf tiruan untuk mendapatkan komposisi yang ideal dan memiliki kuat tekan terbaik. Dimulai dengan proses pencampuran semua bahan, lalu dilakukan pengadukan hingga semua campuran homogen dan mengembang, untuk kemudian dimasukkan ke dalam autoklaf pada suhu 180–190 oC, selama 6-7 jam. Pengujian yang dilakukan antara lain uji XRD (X-Ray Diffaraction), densitas, porositas dan kuat tekan sampel bata ringan. Dari semua sampel uji, dapat diketahui bahwa pada variasi Si 30% dan Al 0,5% yang terbentuk fasa tobermorite. Pada penentuan variasi komposisi, semakin banyak komposisi Si yang digunakan akan semakin meningkatkan kuat tekan bata ringan, dan untuk variasi Ca terhadap kuat tekan komposisi minimal yang diperbolehkan digunakan dalam pembuatan bata ringan yaitu 25%. Untuk hubungan antara nilai porositas dan densitas nilai keduanya berbanding terbalik, semakin besar nilai porositas maka nilai densitas bata ringan menjadi semakin kecil. Dan untuk hubungan antara nilai densitas dan kuat tekan berbanding lurus , yaitu semakin besar nilai densitas bata ringan menjadi semakin besar juga nilai kuat tekan bata ringan. Nilai kuat tekan terbaik dimiliki oleh sampel dengan variasi komposisi Si 30% yaitu 0,306 N/mm2. ================================================================================================================== Aerated Autoclaved Concrete(AAC) lightweight concrete fabrication has been made using variation of Si, Ca, Al. It’s made from cement, silica sand, lime, water and agent foam (aluminum paste) as the developer material. The process of making variation of composition based on previous research that using prediction method of artificial neural network (ANN) to get the ideal composition and have the best compressive strength. It’s begun by mixing all ingredients, then stirring until all the mixture is homogeneous and fluffy, and then fed into the autoclave at a temperature of 180-190 oC, for 6-7 hours. Tests conducted include XRD (X-Ray Diffaraction) test, density, porosity and compressive strength of samples. Of all test samples, it can be seen that in the variation of Si 30% and Al 0.5% formed tobermorite phase. In determining the variation of the composition, the more Si composition used will increase the compression strength of the lightweight concrete, and for the variation of Ca to the compressive strength of the minimum composition allowed in the manufacture of lightweight concrete of 25%. For the relationship between the porosity value and the density value of both are inversely proportional, the greater the porosity value, the smaller lightweight concrete density becomes smaller. And for the relationship between the value of density and compressive strength is directly proportional, that the greater the value of lightweight concrete density becomes greater and also the value of the compressive strength of lightweight concrete. The best compressive strength value is owned by a sample with a 30% Si composition variation of 0.306 N / mm2.
