The usage of agricultural waste in form of ashes as one of the constituent materials in concrete has been studied in recent years. Palm Oil Fuel Ash (POFA) is one of the largest agricultural wastes produced in Malaysia that contain high amount of silica with pozzolanic properties. The mass production of POFA are typically disposed to open area and in turn can generate environmental issues and health hazards. Due to the waste disposal problem, a number of initiatives have been done by utilizing POFA into various construction materials including as substitute to Ordinary Portland Cement (OPC) in concrete production. This paper discusses on the water absorption properties and compressive strength of concrete by utilizing POFA in several series of cement replacement. OPC was replaced by POFA at 2.5%, 5%,7.5% and 10% in these series of mix design. Control OPC concrete sample was also prepared for comparison. The samples were prepared in 100 mm cubic moulds and tested for compressive strength and water absorption for 7, 14 and 28-day curing ages. Three replicates were prepared for each concrete mix and for each test conducted. The results stipulated that the higher percentage of POFA replacement decreased the compressive strength and increased the water absorption amount of concrete mixture over different concrete ages.

The concept of utilizing various types of wastes, such as agricultural dumps and marine by-products, as a partial replacement of cement has gained a great interest to develop eco-friendly and economical mortars for sustainable construction. This study aims to evaluate the feasibility of using palm oil fuel ash (POFA), an agro-industrial waste by-product from palm oil mills and seashell powder (SSP) derived from seashells, a marine waste material partial replacement of cement in mortars. The water to binder (w/b) ratio of 0.49 and the sand to binder (s/b) ratio of 2.54 with 0% to 30% of ordinary portland cement (OPC) by weight was replaced with POFA and SSP, and the resulting mortar samples were tested for mechanical properties and durability in this study. The compressive strength, flexural strength, water absorption, and flow table tests were performed in this study for different percentages of POFA and SSP after 7, 28, and 130 days. The results showed that the 30% POFA incorporated mortars achieved the highest compressive strength (35.12N/mm2), flexural strength (4.06N/mm2), high density with less water absorption (4.79%) after 130 days of curing and the high strength mortar with less water flow (22.2cm) during casting. Also, it found that the 25% POFA and 5% SSP incorporated mortars attained acceptable results as supplementary cementing material. This study suggests that the POFA and SSP incorporated mortars could be used in concrete for sustainable development of construction through the efficient valorization of waste materials.

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
