The consumption of agricultural and industrial wastes has grown rapidly across the world which leads to create large quantities of wastes. It reflects the problem of having a limited number of landfills due to a huge amount of waste produced. Therefore, the solution is recycle the agricultural and industrial wastes as one of the materials use in concrete. Agricultural and industrial wastes were selected as cement replacement in a concrete production. This study aims to investigate the concrete properties containing palm oil fuel ash (POFA) and ceramic tile wastes, such as workability, compressive and splitting tensile strength. The concrete mix design ratio was designed for concrete grade strength 30 and water cement ratio of 0.55. Testing for compressive strength was measured at 7 and 28 days and for tensile strength only at 28 days. This research finds that with combination of 5% POFA and 10% ceramic with 27.1 MPa for compressive strength and 2.5 MPa for tensile strength will be the optimum mix design to replace cement in concrete. This research helps to improve the knowledge, increase the level of environmental awareness and understanding the importance and recycling the construction waste generated.

The growing construction industry that demands for more natural sand supply has indirectly causes the escalation of river sand mining activity. Excessive sand mining affects the water quality and habitats of aquatic life. At the same time, the continuous dumping of palm oil fuel ash, a by-product of oil palm mill causes pollution to the environment. In order to preserve the natural sand and reduce amount of palm oil fuel ash disposed as waste, the present study investigates the potential use of palm oil fuel ash in concrete production. Thus, the effect of unground palm oil fuel ash as partial sand replacement towards workability and compressive strength of concrete is discussed in this paper. A total of six mixes were used in this experimental work. Plain concrete containing 100% river sand was used as reference specimen. The rest of the mixes were prepared by integrating unground palm oil fuel ash by 2%, 4%, 6%, 8% and 10% by weight of sand. All specimens were prepared in form of cubes and subjected to water curing until the testing age. Slump test were conducted on the fresh mix to determine the concrete workability. Compressive strength test were conducted at 7, 14 and 28 days. The finding shows that addition of unground palm oil fuel ash up to 8% does not have significant effect on concrete workability. In terms of compressive strength, inclusion of 6% unground palm oil fuel ash increases the strength of concrete by approximately 13%.

Cement production is a major environmental problem that causes the release of carbon dioxide into the atmosphere. This study attempts to sustainably use palm oil fuel ash (POFA) and eggshell powder (ESP) as partial replacements for Ordinary Portland cement (OPC) in concrete production. POFA and ESP are two wastes that need to be managed to reduce their detrimental environmental effects. As such compressive and slump tests were conducted on POFA-ESP-OPC concrete mixtures by replacing 10% of OPC with POFA-ESP. Two mediums of curing were used: tap water and river water. It was found that the compressive strength and slump resistance of these mixtures were within the ranges typically encountered in regular concrete mixtures indicating the viability of this procedure employed for structural applications.

This paper investigates the stress strain behaviour of concrete containing Palm Oil Fuel Ash and Expanded Polystyrene, axial compressive strength, tensile strength and modulus of elasticity. EPS-POFA concrete was prepared by substituting fine aggregates with EPS beads and cement replaced with POFA by 10%, 20% and 30%. Results of this study showed that EPS-POFA concrete exhibited low axial compressive strength, peak strain, tensile strength and elastic modulus when the EPS and POFA contents in concrete increased. However, the decrease in axial compressive strength of concretes with containing 10 to 20% EPS and POFA are suitable amount and acceptable to be applied on building structure as per stated in America Concrete Institute 318 with minimum specified compressive strength for structural concrete is 2500 psi (17 MPa). While, the failure of EPS-POFA concrete under axial compression gradually occurred and the concretes were able to retain the load after failure without full collapse. The slope of stress-strain curve of concretes with containing EPS and POFA was lower than that of normal concrete, demonstrating that the normal concrete more brittleness that EPS-POFA concretes.

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.

Source Materials

Geopolymer is an inorganic polymer from activation of source materials that rich of silica and alumina with alkaline activator. Previous studies reveal that the geopolymer has engineering properties and durability, which is equivalent or higher than the Ordinary Portland Cement (OPC) concrete. This paper presents properties of geopolymer concrete prepared with local Palm Oil Fuel Ash (POFA) and Fly Ash (FA) from agro-industrial waste in Riau Province, Indonesia. The POFA and FA were activated by a combination of sodium hydroxide and sodium silicate. The specimens were cured at room temperature for 24 hours before steam cured for another 24 hours at 60OC. Hardened properties namely compressive strength, tensile strength, flexural strength and modulus of elasticity, and water penetration of both POFA and FA geopolymer concrete were determined at 7, 14 and 28 days. Results showed that local POFA and FA as geopolymer source materials could produce mix with strength 19-22.5 MPa at 28 days. The compressive strength, tensile strength, flexural strength and modulus of elasticity of both geopolymer tended to increase slightly with time. In general, the results suggest that the local POFA and FA are potential as source material to produce geopolymer concrete.

Two Stages

Prepacked aggregate concrete (PAC) is a type of concrete that is placed in two stages where the coarse aggregates are first placed inside the formworks and then the grout is pumped from underneath through a manual pump. Grout properties including density, grout consistency, bleeding, and compressive strength are of great importance in PAC. Such properties could be improved by application of pozzolanic materials like palm oil fuel ash. This paper is aimed at finding the most optimum percentage of POFA replacement by weight of cement. It was concluded that 30% POFA replacement yielded the most optimum results.

Splitting tensile strength of concrete is normally low compared to compressive and flexural strength. Tensile force was used in the design of structural foamed mortar and to evaluate the shear resistance provided by concrete. This research focuses on the splitting tensile strength of foamed mortar incorporated with 7 different types of fibres used such as wood ash, pulverized fuel ash, silica fume, palm oil fuel ash, polypropylene fibre, coconut fibre and steel fibre. The findings show that the amount of fibres influences the enhancement level of the tensile strength. A high percentage of fibre can create a strong bonding between the particles of the foamed mortar, thus it is able to absorb energy to resist crack formation.
