PENURUNAN KEKUATAN TANAH TERSTABILISASI PALM OIL FUEL ASH BERBASIS ALKALI AKTIVATOR MATERIAL DILINGKUNGAN GAMBUT

نویسندگان

چکیده

Air gambut mengandung pH rendah dan bersifat asam yang korosif pada benda tersementasi seperti tanah terstabilisasi Palm Oil Fuel Ash (POFA) berbasis larutan alkali aktivator. Tanah dicampur POFA dengan kadar 5%, 10% 15% kemudian ditambahkan sodium silika (Na2SiO3) hidroksida (NaOH). Benda uji dipersiapkan untuk propertis tekan bebas. bebas direndam terlebih dahulu kedalam air selama 0, 7, 14 28 hari. Hasil dari sifat fisik menunjukkan campuran menurunkan indeks plastisistas meningkatkan optimum (OMC) serta berat volume kering (MDD). Sedangkan hasil antara tanah, terjadi peningkatan kekuatan 5% diumur 7 hari, masing-masing 760 kPa 1312 kPa. Kemudian terus turun signifikan lebih 50% hari menjadi 365 372 Sedikit konsisten penambahan umur perendaman. Meskipun diperoleh hampir sama lainnya sebesar 356 Proses sintesis aluminasilikat dapat menambah ikatan antar butir menjadikan tahan terhadap serangan asam.

Binary Effect of Fly Ash and Palm Oil Fuel Ash on Heat of Hydration Aerated Concrete

The binary effect of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) on heat of hydration of aerated concrete was studied. Three aerated concrete mixes were prepared, namely, concrete containing 100% ordinary Portland cement (control sample or Type I), binary concrete made from 50% POFA (Type II), and ternary concrete containing 30% POFA and 20% PFA (Type III). It is found that the tempe...

Development of Self-Consolidating High Strength Concrete Incorporating Treated Palm Oil Fuel Ash

Palm oil fuel ash (POFA) has previously been used as a partial cement replacement in concrete. However, limited research has been undertaken to utilize POFA in high volume in concrete. This paper presents a study on the treatment and utilization of POFA in high volume of up to 50% by weight of cement in self-consolidating high strength concrete (SCHSC). POFA was treated via heat treatment to re...

Modeling of Compressive Strength for Self-Consolidating High-Strength Concrete Incorporating Palm Oil Fuel Ash

Modeling is a very useful method for the performance prediction of concrete. Most of the models available in literature are related to the compressive strength because it is a major mechanical property used in concrete design. Many attempts were taken to develop suitable mathematical models for the prediction of compressive strength of different concretes, but not for self-consolidating high-st...

Pore Structure Changes of Blended Cement Pastes Containing Fly Ash, Rice Husk Ash, and Palm Oil Fuel Ash Caused by Carbonation

In this paper, the effects of carbonation on pore structure of blended pozzolan cement pastes were investigated. Ordinary Portland cement OPC was partially replaced with ground palm oil fuel ash POA , ground rice husk ash RHA and classified fine fly ash FA . The strength, total porosity, specific surface area, and pore size distribution were tested. In general, incorporation of pozzolans increa...

Preparation and Characterization of Nano- Structured Materials from Oil Palm Ash: a Bio- Agricultural Waste from Oil Palm Mill

Oil palm ash (OPA), a bio-agricultural waste from oil palm mills, was subjected to high-energy ball milling for 30 h and was converted into a nano-structured material. The nano-structured OPA was characterized for its particle size and crystallinity index by using Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) analysis. The crystallite size obtained from TEM and XRD was foun...
