Palm Oil Fuel Ash

Pofa is rich in sio 2 therefore is a good pozzolanic material.

Palm oil fuel ash. The application of palm oil fuel ash pofa and fly ash fa as an alumino siliceous precursor to create a viable geopolymer binder for the manufacture of unfired lightweight masonry units using soft soil ss as aggregate was studied in this research. These problems can be reduced to a large extent by using pofa in concrete. It not only occupies land but also creates environmental pollution and health hazards. Investigation on the adsorbency characteristics of pofa suspension revealed that the surface area particle size composition and crystallinity of the sio 2 rich mullite structure were the crucial factors in ensuring a high adsorption capacity of the ions.

Pofa reduces drying shrinkage as well as workability of concrete. The pofa obtained was sieved to 75mm in the laboratory to remove coarse particles. Palm oil fuel ash which contains siliceous compositions produces a stronger and denser concrete. The problems can be lessened by making use of pofa as cement replacement materials.

Abstract uncontrolled dumping of palm oil fuel ash pofa not only occupies valuable land but also creates environmental pollution and health hazard. This is to ensure that only small particle sized pofa were used to obtain a better control over. The contribution of palm oil fuel ash pofa an agricultural waste as a low cost adsorbent for the removal of arsenite as iii and arsenate as v was explored. Palm oil fuel ash pofa a by product from the palm oil industry is disposed of as waste in landfills.

Palm oil fuel ash pofa is a waste materials dumped into an open field of a palm oil industry and thus caused environmental contamination and health threat problems. Palm oil fuel ash pofa a waste material obtained from burning of palm oil husk and palm kernel shell as fuel in palm oil mill boilers which has been identified as a good pozzolanic material. These problems can be reduced to a large extent.
