Effects of Palm Oil Fuel Ash as Micro-Filler on Interfacial Porosity of Polymer Concrete

The effects of palm oil fuel ash (POFA) as micro-filler on interfacial porosity and pore size distribution of polymer concrete (PC) is the main aim of this chapter. Beginning with a brief introduction about the topic, the materials and method used in this study are explained. Two categories of fillers were involved in this study, fine-micro filler (ground POFA and is paired with calcium carbonate), and coarse micro-filler (unground POFA and is paired with silica sand). It is revealed that the replacement of overall types of micro-filler at different filler content decreased the average pore diameter of PC significantly, except for PC incorporating unground POFA. Additionally, incorporation of fine-micro filler with dispersion characteristic could significantly reduce the interfacial porosity of PC as compared to incorporation of coarse micro-filler in PC.

This paper presents the potential of utilizing an agricultural waste known as palm oil fuel ash (POFA) as micro-filler in polymer concrete (PC). Being a plant with open cellulose structure, such potential has gone untapped due to its tendency to take up excessive resin during the mixing process. This study has invested its filler characterization by first segregating the POFA fillers into fine (ground POFA, GPOFA) and coarse (unground POFA, UPOFA) fillers. GPOFA was paired with calcium carbonate while UPOFA was with silica sand for comparisons. Filler characteristics were studied under microstructural examination; particle size analyzer and morphology. Twenty design mixes of polymer blended and polymer concrete were casted for flowability and compression tests, respectively. Further investigations were carried out after two categories of fillers were incorporated with different filler contents.  Test data showed that filler had changed its physical features significantly after surface modification. Also, the finer fillers gave superior filling ability and compressive strength. This study concluded that POFA can be potentially transformed into effective PC filler following some physical modifications and mixing with the appropriate design mix.

Research of  the utilization solid waste of palm oil fuel ash from boiler as row materials  for manufacturing light concrete brick has been conducted. The main objective of this study is to investigate the potential use solid waste of palm oil fuel ash from palm oil mill boilers as row materials for manufacturing light concrete brick has recently attracted for an alternative environmentally sustainable application. In this study, light concrete brick made with various proportions of palm oil fuel ash from palm oil mill boilers and sand were fabricated and studied under laboratory scales. Percentage of palm oil fuel ash of 0% as a control,  10%, 20%, 30%, 40%, 50%, 60%, replacement  sand, wheras others materials such as Portland cement, lime, gypsum, foaming agent and aluminium with the numbers constant. The quality of light concreate brick   were applied followed by the compressive strength test, density and water absorption capacity. The study discovered that the compressive strength for all composition meet the recommended value to light structural of 6.89 MPa as prescribed in SNI 03-3449-2002. In the same manner density of light concrete brick for all proportion under the maximum density recommended value of 1400 Kg/m3 according to SNI 03-3449-2002. While water absorption capacity of increased by the increasing use of ashes. Therefore, palm oil fuel ash from boiler can be used as raw material for the light concrete brick which is  environmental friendly because using solid waste and also an alternative handling solid waste.ABSTRAKPenelitian pemanfaatan limbah padat abu cangkang dan serat kelapa sawit dari boiler sebagai bahan baku pembuatan bata beton ringan telah dilakukan. Tujuan dari penelitian ini adalah pemanfaatan limbah padat abu boiler berbahan bakar cangkang dan serat sebagai bahan pembuatan bata beton ringan sebagai salah satu alternatif pengelolaan lingkungan yang bekelanjutan. Dalam penelitian ini, bata beton ringan dibuat dengan berbagai komposisi abu boiler dan pasir yang diproduksi dalam  skala laboratorium. Persentase dari abu berturut-turut 0% sebagai kontrol, 10%, 20%, 30%, 40%, 50% dan 60% mensubtitusi pasir, sedangkan bahan lain yaitu semen, kapur, gypsum,  foaming  agent serta aluminium pasta dengan jumlah tetap. Mutu bata beton ringan yang diujikan adalah kuat tekan, bobot jenis dan daya serap air. Hasil penelitian menunjukkan bahwa kuat tekan untuk semua komposisi memenuhi batas minimum yang dipersyaratkan untuk stuktural ringan yaitu 6,89 MPa sesuai SNI 03-3449-2002. Demikian pula bobot jenis dari bata ringan yang dihasilkan masih dibawah dari batas maksimum yang direkomendasikan SNI 03-3449-2002 yaitu maksimal 1400 Kg/m3. Sedangkan daya serap air mengalami kenaikan dengan naiknya jumlah abu yang digunakan . Limbah padat abu boiler berbahan bakar cangkang dan serat sawit dapat dimanfaatkan sebagai bahan baku pembuatan bata beton ringan yang ramah lingkungan dengan memanfaatkan limbah dan menjadi salah satu alternatif pengelolaan limbah. Kata kunci :  Abu cangkang kelapa sawit,  bata beton ringan, bobot jenis,  daya serap air,  limbah,  kuat tekan
