Use of oil palm shell as an aggregate in cement concrete

Palm oil fuel ash (POFA), ground granulated blast furnace slag (GGBS) and metakaolin (MK) were used as binders; while palm oil clinker (POC) and oil palm shell (OPS) used as coarse aggregate

Structures were constructed on the c ampus, which is located near the coastal area. When OPS blended with cement, it makes the most eco-friendly versatile supplementary cementing material to concrete. Reported in the paper are compressive strength, workability and density of oil palm shell concrete.

Oil-palm-boiler clinker (OPBC) is an agricultural solid waste sourced from the palm oil industry in tropical regions. This This study investigates the use of OPBC as coarse aggregate instead of conventional coarse aggregates to produce a greener

Due to environmental issues, the use of waste materials in concrete is gaining popularity. Waste materials, such as oil palm shell (OPS) and palm oil clinker (POC) from the Malaysian palm oil industry are being used in various researches to produce lightweight concrete. Concrete containing only

palm provides food, drink, clothing, shelter, heirloom his-tory, and financial security [3]. Hardly an inch of the coconut palm goes to waste in countries such as the Philip-pines where families rely on the coconut palm for survival and refer to it as the "tree of life." The shell, husk, roots of the tree, fronds, flowers, and

3. Eggshell as a Fine Aggregate in Concrete for Sustainable Construction by S. A. Raji, A. T. , 2015 [3] This experiment has investigated the use of egg shell at 100% replacement level as a fine aggregate in concrete. This results a reduction in compressive strength of the concrete but still falls within limits of light weight concrete.

This research showed the results of experiments evaluating the use of palm kernel shell powder from palm oil refinery waste production as partial replacement of Ordinary Portland Cement (OPC). Many researchers have studied the use of agro-waste as constituents in concrete but not as a partial replacement of cement specifically. Therefore, the objective of this research is to identify the

aggregate replacement in concrete production. Keywords: Lightweight concrete, palm kernel shell, compressive strength, coarse aggregates, concrete 1. INTRODUCTION Concrete which is an admixture of water, aggregates (coarse and fine) and cement, is a heterogeneous construction material

Other forms of concrete deterioration exist, including freeze-thaw damage, alkali-aggregate reaction and sulfate attack, but less common in cast-in-place concrete wall systems. Maintainability Durability of concrete and resistance to deterioration is dependent on durability, proper design, and good workmanship.

concrete beams containing oil palm shell. The beams with varying reinforcement ratios were investigation revealed that the flexural behaviour of reinforced concrete beams made from oil palm shell aggregate was comparable to that of other lightweight concretes and the (cement): 6 (natural aggregate).

The materials used in this work are palm oil waste (empty fruit bunches, palm kernel shells and fruit fiber), Ordinary Portland Cement (OPC), aggregates (fine and

All of the mortars had a cement-to-aggregate ratio of 1:3, and the water-to-cement ratio was set to 0.5. In the control mix with 100% natural sand, the sand was substituted

3.1. Density of Concrete Specimens. The dry density of the palm kernel shell lightweight concrete is illustrated in Figure 4.The result shows that on the 21-day of curing, the lowest density (1447.27 kg/m 3) and the highest density (1714.27 kg/m 3) were recorded respectively for 6 and 10 mm PKS sizes replacement of coarse aggregate in the concrete.The densities of the concrete obtained on the

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.

Palm kernel shells (PKS) are the shell fractions left after the nut has been extracted from crushing operation in the palm oil mill. PKS can be used in industrial boilers, furnaces and foundries, brick kilns, residential and commercial heating, and light-weight aggregate for concrete as an alternative fuel for biomass-based which combined heat
