“…Gibigaye et al, (2017) [33] investigated the proportioning of mixture for oil palm kernel shell lightweight concrete with batches of 1:1.6:0.96 and 1:1.53:0.99 for C:S:OPKS ratio with cement content of 450kg/m³, which produced a minimum slump of 20 mm, density between 1800 and 1900kg/m 3 , and minimum compressive strength of 15N/mm². Yusuf et al (2018) [34] carried out an experiment on the structural application of lightweight concrete incorporated with palm kernel shells adopting a mix ratio of 1:1:2 and w/c of 0.5. PKSC beam at 28 days showed flexural strength of 2.883 N/mm² and deflection of 0.947 mm indicating resistance to load of 3981N.…”

The implications of palm kernel shell (PKS)-filled plastic bottles on the structural behaviour of concrete slabs were carried out by comparing the flexural performance of conventional solid concrete slabs to concrete slabs incorporated with plastic bottles filled with palm kernel shells and placed vertically, horizontally, and diagonally at the neutral axis of the slab as per Bubble Deck Slab technology. One-way slab specimens of size 700 × 300 × 150 mm thick were produced and subjected to a four-point flexural load test. Findings from the study indicated that: (1) The PKS-filled bottle slabs deflected more than the conventional solid slab, hence making them more flexible than the conventional slabs and, as such, giving the occupants enough time to evacuate. (2) The flexural strengths of the PKS-filled bottle slabs exceeded those of conventional slabs by 18.3% and 10.9%, respectively, for five and ten percentages of the volume of slab concrete occupied. (3) The condition of the PKS, either dry or saturated, coupled with the bottle arrangement (either vertical, horizontal, or diagonal), does not, however, cause any significant change to the performance of the PKS filled bottle slabs in terms of load carrying capacity, deflection, and strength.

Palm kernel shells (PKS) and waste automobile tires do not only enhance the properties of concrete (e.g. damping ratio, ductility, impact resistance etc.), but also their rational utilization can significantly reduce carbon footprints and environmental pollution globally. In this study, a multivariate regression analysis was carried out to develop models for predicting the reduction factors and thereafter the strengths (compressive strength, flexural tensile strength, split tensile strength and bond strength) of concrete that utilizes PKS and waste automobile tire chips as partial to full replacement of the conventional crushed granite stones as coarse aggregates. The strength reduction factors, , were modelled as a function of the total aggregate replacement level (TAR), and the volume of PKS (P) and tire (T) particles in a given concrete mix whilst the performance of the models was assessed using the Mean Squared Error (MSE) and the Coefficient of Determination () techniques. After studying several mathematical functions, it was found that a single linear regression model can be used to predict the strength reduction factors for all the mechanical properties of the concrete tested but with different function parameters. The values of the ranged from 0 to 1 depending on the aforementioned factors. However, a of 0.53 (53%) can be achieved at the 50% optimum replacement where P50T50 for any of the mechanical properties. Furthermore, for each of the concrete properties, the was positively correlated with the volume of PKS but negatively correlated with the TAR level and volume of tire particles in the concrete matrix. Thus, an increase in the TAR level or tire content decreases the and vice versa. In conclusion, the proposed models can be used to establish the target strengths of PKS.
