“…The first two are widely used as mulch and soil improvers in palm plantations, and fibre and shell are increasingly used as fuels in the oil mills (Yusoff 2006). Ash can be mixed with concrete (Tangchirapat et al 2007) and shells to surface plantation roads (Yusoff 2006), while methane from mill effluent fermentation can also provide energy for mills (Yacob et al 2006). Treated palm trunks can be made into furniture (Darnoko 2002cited in Simorangkir 2007.…”

“…In recent years, studies on using waste generated from agricultural and industrial activities as partial replacement of cement in concrete have been growing rapidly [15][16][17][18] Many researchers have studied the use of agrowaste ashes as constituents in concrete. The findings revealed that this agro-waste ash containsa high amount of silica in amorphous form and can be used as a pozzolanic material [12,19,20]. Previous researchers found that the pozzolanic activity indices of POFA at about 78.6% to 87.6%, are much higherthanother classes of pozzolanic ash, at about 75% (ASTM C 618-94a; Sumadi and Hussin [21]; Abdul Awal and Hussin [19]).…”

“…Abdul Awal and Hussin [9] have proved that this waste could be used as a partial cement replacement in concrete for the production of stronger and more durable construction material. Following these findings, more researchers have integrated POFA as one ingredient in the mix to produce a new type of concrete [10][11][12][13]. POFA is a by-product produced in palm oil mills.…”

The investigation of the effect of curing conditions on self-healing of pre-cracked concrete containing palm oil fuel ash (POFA)-concrete is presented. Concrete grade 30 was used and POFA cement replaced 10%, 20% and 30% of the total weight of ordinary Portland cement [1].The compressive strength was tested after 7, 28, 60 and 90 days cured in water in order to investigate the strength development of the POFA-concretes. In addition, the pre-crack (hairline crack) concrete was examined under compression load to determine the effectiveness of self-healing POFA-concretes after different curing conditions. Four types of curing condition, namely air, room temperature, wet and dry, and water curing were tested. An ultra-pulse velocity (UPV) test was performed after 7, 28, 60 and 90 days of curing to monitor the self-healing progress in the POFA-concrete. The results show that POFA-concrete witha 20% replacement level recorded the highest compressive strength. It was also revealed that the UPV readings increased significantly with increased curing age. The results showed that the selfhealing ability of pre-cracked POFA-concrete at 10% replacement level increases significantly for the water curing condition. From these findings, the optimum POFA replacement level was recorded at 20% for the strength, while inclusion of a 10% POFA replacement level was appropriate for self-healing concrete.

“…In order to resolve these problems, several studies were conducted to examine the feasibility of using POFA in construction materials [6]. In Thailand, the palm oil fuel ash (POFA) has beeen utilized as a pozzolanic material in concrete [7]. On the other hand rice husk is an agricultural waste that can be easily obtained in mass quantity locally.…”

Abstract. The production of sustainable construction component could prevent and control the pollution and environmental degradation in Malaysia. This is a key area in Malaysia's Green Strategies (Ministry of Science, Technology and the environment, 2002). This paper reports on the laboratory investigation to establish the potential of utilizing Palm Oil Fuel Ash (POFA) and Rice Husk (RH) in developing green construction components. Malaysian Palm Oil Council (MPOC) reported that currently Malaysia's contribution to world palm oil production is 39% and has taken 44% of world exports. Consequently it will increase the POFA production in palm oil manufacturing and this waste sometimes dispose in open area near the factory. On the other hand Malaysia also producing more 300k hectares of paddy production, thus rice husk is also a concern as an agricultural waste. The research objective is to study on the potential of utilizing of agricultural waste in developing of green bricks. This research involved laboratory investigations. In this research 2% -10% of POFA and 1% -5% RH were used in the mix composition of the brick's weight. Addition of POFA was aimed to reduce the cement usage and RH was added to reduce sand in the bricks. The bricks were manually pressed in Materials Laboratory in Faculty of Architecture, Planning and Surveying, UiTM Shah Alam. The result showed that the addition of POFA and RH are able to reduce the density but in contrast the compressive strength were decrease compare to the control unit.
