Abstract This study presents the potential of modified Palm Kernel Shell (MPKS) particles in the production of blocks as an alternative building material using cement or clay as binders. Several studies on Palm Kernel Shell (PKS) as a blend with other natural fibres/fillers found that due to its hydrophilic nature, it has low physical and mechanical capabilities in comparison to MPKS, making it less compatible with any polymeric matrix. Experimental tests were conducted to determine the physicomechanical attributes of MPKS/Cement and MPKS/Clay blocks, including characterization of the cement and clay using Atomic Absorption Spectroscopy (AAS), as well as moisture content, water absorption, hardness, apparent porosity, bulk density, compressive strength, and flake. The morphology of the samples was determined using Scanning Electron Microscope (SEM). Results show that MPKS/Cement block samples exhibit superior physicomechanical and morphological properties compared to MPKS/Clay. The MPKS/Cement block sample moisture content ranged between 4.76 – 9.94%. The 80/20 MPKS/Cement sample recorded the most water absorption at 49.5%, and a microhardness value of 82.3 Hv for the 20/80 sample. The MPKS/Clay samples showed higher values of apparent porosity but recorded the least bulk density in the 80/20 samples. The 20/80 MPKS/Cement and MPKS/Clay samples showed the best compressive strength at 63.72 and 50.3 N/mm2 respectively, while 80/20 for both cement and clay displayed very weak compressive strengths. The ratio 20/80 of MPKS/Cement is observed to be the optimum ratio where better properties of the composites were obtained. For the structure industry's long-term viability, MPKS' superior mechanical properties as an aggregate in block manufacturing make it an asset material as an alternative for some high-cost construction resources such as sand.

Abstract This paper presents an experimental study to investigate the sustainable alternativeceiling boards using Palm Kernel Shell (PKS) and Balanite Shell (BS). The ceiling boards were prepared by mixing (BS/binder, PKS/binder and PKS/BS/binder) at different ratios of (20/80, 40/60, 60/40 and 80/20) and represented as samples (A1, A2, A3 and A4), (B1, B2, B3 and B4) and (C1, C2, C3 and C4) respectively. The samples werecast by flat press process in rectangular sheet shape mould of 187mm x 125 mm x 3mm. The samples were cut into specimen sizes of 30 mm x 40 mm and tested for dry shrinkage, water absorption, apparent porosity, bulk density,flaking, and hardness properties. Morphology of the samples were examined using SEM. Results of the analysis show that irrespective of the filler loadings the properties of PKS / binder particularly at 20/80 ratio (B1) displayed better dry shrinkage of 3.7 %; water absorption of 12.4 %; apparent porosity of 15 %; bulk density of 2.3 g/cm3; flaking of 0.05g and hardness of 57.6 Hv which approximates those of the conventional specimen (Control) with a more better physical properties compared to BS / binder at 20/80 ratio (A1) with dry shrinkage of 6.1 %; water absorption of 33 %; apparent porosity of 35 %; bulk density 1.2 g/cm3; flaking of 0.36g; hardness of 26.2 Hv and PKS / BS / binder at 20/80 ratio (C1)with dry shrinkage of 9.8 %; water absorption of 30 %; apparent porosity of 32 %; bulk density 1.4 g/cm3; flaking of 0.1g; hardness of 36.7 Hv. These results therefore suggest that PKS could be used as a sustainable alternative in the production of ceiling boards.

The objective of this study was to recycle powdered marble dust to improve mechanical properties and thermal conductivity of lightweight clay bricks. Varying amounts of powdered marble dust (10, 20, 30, and 40 vol.%) were added to a lightweight clay brick at the firing temperatures of 900, 1000, and 1100 °C. When higher quantities of powdered marble dust were added, the values of porosity and water absorption increased while those of thermal conductivity and bulk density decreased. The decrease in apparent porosity and water absorption were also affected by the increase in firing temperature. The most desirable properties of the clay bricks were obtained for the powdered marble dust content of 40 vol.% and firing temperature 900 °C: bulk density of 1.20 g/cm3, compressive strength 9.2 MPa, thermal conductivity 0.32 W/m.K, and water absorption 22.5%.

Clay Bricks

In this paper, effects of incorporation of dry grass on the properties of clay bricks were investigated. Clay bricks fabricated with 0, 2.5, 5 and 7.5 % (w/w) of dry grass were tested. The clay brick specimens were fired at 900, 1000 and 1100 °C to study for bulk density, apparent porosity water absorption and compressive strength of brick samples were investigated. Results revealed that the bulk density of clay bricks were reduced when dry grass dosages increased. Results also shown that the increasing in bulk density were obtained when the firing temperature increased. The compressive strength of clay bricks was decreased when dry grass dosages increased. The addition of 2.5 % (w/w) dry grass fired at 1100 °C showed the optimal condition which indicated 11.6 MPa of compressive strength and 1.78 g/cm3 of bulk density. However, results indicated that a decrease in water absorption and apparent porosity were found when the firing temperature increased. Test results also revealed that the addition of dry grass for clay brick production lead to utilize a potential material as the additive to raw clay-bricks in the manufacturing of lightweight clay bricks.

This study focuses on the evaluation of the physical and mechanical properties of a porous material based on a mixture of powder (Volcanic ash /Aluminum Beverage Cans) and a solution of phosphoric acid. Volcanic ash (VA) use was collected in one of the quarries of Mandjo (Cameroon coastal region), crushed, then characterized by XRF, DRX, FTIR and named MaJ. The various polymers obtained are called MaJ0, MaJ2.5, MaJ5, MaJ7.5 and MaJ10 according to the mass content of the additions of the powder from the aluminum beverage cans (ABCs). The physical and mechanical properties of the synthetic products were evaluated by determining the apparent porosity, bulk density, water absorption and compressive strength. The results of this study show that the partial replacement of the powder of VA by that of ABC leads to a reduction in the compressive strength (5.9 - 0.8 MPa) and bulk density (2.56 – 1.32 g/cm3) of the polymers obtained. On the other hand, apparent porosity, water absorption and pore formation within the polymers increases with addition of the powder from the beverage cans. All of these results allow us to agree that the ABCs powder can be used as a blowing agent during the synthesis of phosphate inorganic polymers.

Physical and mechanical properties of seven ancient clay brick samples of Kathmandu valley consisting of quartz, feldspars, spinel, margarite, muscovite type of mica mineral and hematite were studied using ASTM standards. All the brick samples used in this study have the water absorption, apparent porosity and bulk density in the range of 10-28 percent, 17-33 percent and 1.2-1.8 g/cm3, respectively, while the compressive strength of all the brick samples is found to be in the range of 5-23 MPa. The bulk density of the tile samples is found to be increased with decreasing the water absorption and apparent porosity. The compressive strength of all the clay brick samples can be correlated with their physical properties. Consequently, durability of the ancient bricks is directly influenced by their physical properties of water absorption, apparent porosity and bulk density.

Turmeric (Curcuma longa L) in Indonesia is widely known as a herbal medicinal plant, food coloring, and food flavoring. The high water content of turmeric will shorten the storage time and the quality of the ingredients. The need for drying which is the process of removing the moisture content of the material with the aim of prolonging the shelf life. The use of the foam-mat drying method with the addition of adhesives aims to speed up the drying process and maintain the quality of a material. The result of drying turmeric obtained is turmeric powder product. This study used a completely randomized design (CRD) with two factors, namely the variation of the microwave oven power and the composition of the developer agent (ovalet). The research procedure was divided into two stages, namely the manufacture of powder and continued with the measurement of physical quality. The stages of making powder begin with the preparation of raw materials, stripping, size reduction, addition of developer, drying, then grinding. The second stage is measuring physical quality, namely fineness modulus, average grain size, powder moisture content, color, water absorption, oil absorption, and bulk density. The power variations used are 420 watts, 535 watts, and 680 watts, while the composition of the developer is 1%, 2%, and 4%. Data analysis using two-way ANOVA statistical test with two factors that affect the variation of power and composition of the developer (ovalet). FM values ​​ranged from 0.364 – 1.576, D values ​​ranged from 0.005 – 0.0012 mm, final moisture content values ​​ranged from 7.60 – 9.59%, powder moisture content values ​​ranged from 9.47 – 11.43%ww , L values ​​ranged from 61.46 – 65.96, a values ​​ranged from 13.54 – 16.05, b values ​​ranged from 48.21 – 52.42, DSA values ​​ranged from 2.78 – 3.54 ml/ g, DSM values ​​ranged from 1.22 – 1.60 ml/g, and DC values ​​ranged from 0.38 – 0.44 g/cm3. The combination treatment of drying power with developer is influenced by the drying power of the parameters, namely the value of moisture content, fineness modulus, average grain size, brightness level, redness level, yellowness level, oil absorption, water absorption, and bulk density. While the developer affects the finenes modulus, average grain size, yellowness level, and bulk density.

This study examined the effect of varying water cement ratio on the compressive strength of concrete produced using palm kernel shell (PKS) as coarse aggregate at different replacement levels. The replacement levels of coarse aggregate with palm kernel shells (PKS) were 0%, 25%, 50%, and 100% respectively. PKS concrete cubes (144 specimens) of sizes 150mm x 150mm x 150mm were cast and cured in water for 7, 14, 21 and 28 days respectively. A mix ratio of 1:2:4 was adopted with water-cement ratio of 0.45, 0.5, and 0.6 respectively while the batching was done by weight. Slump test was conducted on fresh concrete while compressive strength test was carried out on the hardened concrete cubes using a compression testing machine of 2000kN capacity. The result of tests on fresh concrete shows that the slump height of 0.45 water cement ratio (w/c) increases with an increase in PKS%. This trend was similar to 0.50 and 0.60 w/c. However, the compressive strength of concrete cube decreases with an increase in w/c (from 0.45 to 0.60) but increases with respect to curing age and also decreases with increase in PKS%. Concrete with 0.45 water-cement ratio possess the highest compressive strength. It was observed that PKS is not a good substitute for coarse aggregate in mix ratio 1:2:4 for concrete productions. Hence, the study suggest the use of chemical admixture such as superplasticizer or calcium chloride in order to improve the strength of palm kernel shells-concrete.

In this study, the physico-mechanical and morphological properties of polyvinyl alcohol/palm kernel shell/coconut kernel shell elastomeric polymer nanocomposites (PVA/PKS/CKS EPNCs) were investigated. PVA/PKS/CKS EPNCs were prepared via solution casting method and the properties of the elastomeric polymer nanocomposites were characterized through Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), tensile testing and moisture absorption test. Test results showed that increasing the PVA content increased the mechanical properties of elastomeric polymer nanocomposites as well as provided better surface morphology. However, beyond certain percentage of PVA content, the moisture absorption increased too. Therefore, 55wt% of PVA/PKS/CKS EPNCs was chosen as the best elastomeric polymer nanocomposites as it had the best overall properties from the aspect of physico-mechanical, morphological and moisture absorption.

Compressive Strength Of Concrete

The evaluation of agro-industrial by-products as alternative construction materials is becoming more significant as the demand for environmentally friendly construction materials increases. In this study, the workability and compressive strength of concrete produced by combining Palm Kernel Shell (PKS) and Rice Husk Ash (RHA) was investigated. Concrete mixes using a fixed content of 15% RHA as replacement for cement and 20, 40, 60, 80 and 100% PKS as replacement for crushed granite by volume with the mix ratios of 1:1½:3, 1:2:4 and 1:3:6 were produced. The water-to-cement ratios of 0.5, 0.6 and 0.7 were used for the respective mix ratios. Concrete without PKS and RHA served as control mix. The fresh concrete workability was evaluated through slump test. The concrete hardened properties determined were the density and compressive strength. The results indicated that the workability and density of PKSC were lower than control concrete, and they decreased as the PKS content in each mix ratio was increased. The compressive strength of concrete at 90 days decreased from 27.8-13.1 N/mm2, 23.8-8.9 N/mm2and 20.6-7.6 for 1:1½:3, 1:2:4 and 1:3:6, respectively as the substitution level of PKS increased from 0-100%. However, the compressive strength of concrete increased with curing age and the gain in strength of concrete containing RHA and PKSC were higher than the control at the later age. The concrete containing 15% RHA with up to 40% PKS for 1:1½:3 and 20% PKS for 1:2:4 mix ratios satisfied the minimum strength requirements for structural lightweight aggregate concrete (SLWAC) stipulated by the relevant standards. It can be concluded that the addition of 15% RHA is effective in improving the strength properties of PKSC for eco-friendly SLWAC production..
