Experimental Study on Palm Kernel Shells as Coarse Aggregates in Concrete Daniel Yaw Osei, Emmanuel Nana Jackson Abstract— This paper reports on experimental investigations on the effects of replacing crushed granite in concrete with palm kernel shells on the strength, density and workability of concrete.

These concrete mixes of widely differing water/cement ratios were made using palm kernel shell as course aggregate. The properties tested include the physical properties of the shell, the compressive, flexural and tensile splitting strengths of the concrete.
Workability Previous study [10] has conducted experimental research on palm kernel shells as coarse aggregates in concrete. The workability of concrete will decrease due to increasing percentage of OPS. This happen because of increasing the specific surface as a result increases the quantity of palm kernel shell.
The results also indicated cost reduction of 30% and 42% for concrete produced from coconut shells and palm kernel shells, respectively. Considering the strength/economy ratio, it was concluded that coconut shells were more suitable than palm kernel shells when used as substitute for conventional aggregates in concrete production. r 2005 ...
Palm Kernel Shell is the residual crushed shells from the extraction process of crude palm oil. It is fibrous material that can be easily handled in bulk directly from the product line to the end use. Today, PKS is considered to be an affordable and renewable source of biofuel.
Aug 11, 2014· It can therefore be concluded that palm kernel shell is a lightweight aggregate and can be used to produce lightweight concrete. Keywords: Palm kernel shell, lightweight aggregate.
B. Palm Kernel Shell Ash The palm kernel shell burnt to ash in this research work was obtained from a black smith workshop in Igbara – Odo Ekiti, Ekiti State, Nigeria. The ash was sieve using sieve number 0.425mm and only ash particles that pass through sieve was used in the concrete preparation. C. Fine aggregates
nel shells and reduce cost of construction.Palm kernel shells could be employed for construction purposes in rural villages where they are easily accessible and places where natural occurring aggregates are expensive.In this paper,ineering properties of concrete made with varying percentage of palm kernel shells as aggre - gate is determined ...
Determine the workability of concrete made with palm kernel shells as compare with workability of concrete made with normal weight aggregate. Produce palm kernel shells concrete with minimum strength of 13.225 N/mm 2 as specified by ACI 38 section 1909.1.1 and BS1881-116.
Palm kernel shells (PKS) or oil palm shells (OPS) are organic waste materials obtained from crude palm oil producing factories in Asia and Africa. In recent years, many research works on the use of palm kernel shells (PKS) as lightweight aggregate (LWA) to produce lightweight aggregate concrete (LWAC) have been
The Feasibility of Palm Kernel Shell as a Replacement for Coarse Aggregate in Lightweight Concrete Zarina Itam1*, Salmia Beddu1, Nur Liyana Mohd Kamal1, Md Ashraful Alam1, Usama Issa Ayash1 1Department of Civil Engineering, Universiti Tenaga Nasional, Malaysia E-mail: [email protected]
observed that the compressive strength of palm kernel shell and the normal weight concrete. It also shows that the Normal weight concrete has a higher compressive strength than palm kernel shell concrete. The values obtained from the compressive strength for various days was plotted via the use of bar chart as shown in figure 1.
Sep 23, 2018· Palm kernel shell is light and ideal for substitution as aggregate in the production of light weight concrete. Olutoge (1995) in his investigation into the physical property of palm kernel shell found that it has density to be 740kg/m 3.He concluded that this material have properties which resembled those light weight concrete materials.
shell as a partial replacement of fine aggregates in concrete. This studied were used the different percentage of palm kernel shell as a partial replacement of fine aggregates in concrete at 1%, 2%, and 3% by volume of sand. Palm kernel shells are derived from the oil palm tree (elaeis guineensis), an economically valuable tree because of its oil.
Dec 24, 2016· Periwinkle shell was chosen as a substitute for coarse aggregate in concrete [1] and palm kernel shell was used as a replacement for fine aggregate in concrete by some researchers [2].
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. Palm oil fuel ash which contains siliceous compositions produces a stronger and denser concrete.
physical properties of palm kernel shell obtained by Peter (2006) are shown in Table 1. Crushed Palm Kernel Shell (CPKS) and Palm Kernel Shell (PKS) can be used as a suitable as partial replacement for coarse and fine aggregates respectively in asphaltic concrete up to 80% in Light Traffic roads. CPKS can be used as a
study is the combination of coconut shell and grained palm kernel shell has potential as lightweight aggregate in concrete. Also, using the combination of coconut shell and grained palm kernel as aggregate in concrete can reduce the material cost in construction because of the low cost and abundant agricultural waste.
