Characteristics of Oil Palm Fruit Ash as Binder in Asphaltic Concrete

In order to reduce energy and natural resource consumption during road construction, the sustainability concept needs to be seriously addressed. Oil Palm Fruit Ash (OPFA) is one of the by-products of palm oil production that are typically disposed of in landfills as a result of the growing number of plantations in Malaysia, particularly in Sarawak. Due to the fact that OPFA is known as biomass with pozzolanic qualities (siliceous material), this study was carried out to examine the applicability of OPFA with varying concentrations (0% - 40%) by weight as a modifier in bitumen grade 60/70. Based on the results of the laboratory testing, it was discovered that the modified bitumen provided greater resistance to rutting, temperature, and skid resistance on the bituminous mixture (AC20) compared to the control sample. The 40% OPFA modified samples had the greatest resilient modulus test value, measuring 10992 MPa at 25 °C and 2936 MPa at 40 °C, respectively. In addition, the combination containing 40% OPFA produced the lowest deformation value in the dynamic creep test, which was only 0.20mm, while producing 83.63 skid numbers in the skid resistance test. OPFA can be utilized as a binder modifier to improve the performance of bituminous mixture, which indirectly supports the sustainable development goals (SDGs) concept in road construction, as this study conclusively demonstrated.

Dimensionnal stability and strength appraisal of termite hill soil stabilisation using hybrid bio-waste and cement for eco-friendly housing

Dimensional stability and compressive strength are key factors to consider when modelling earth-based materials. It defines the volumetric performance of earth-based materials upon wet and dry environment. Meanwhile, the deformation under compression loading is accessed with the compressive strength testing. This study is aimed to use locally available materials considered as waste to model sustainable construction materials through soil stabilisation technique. The utilization of biowaste in this study is aimed to reduce the amount of waste produced in the agricultural sector in addition to the promotion of this material locally in the construction field. Cement was used as stabilizer to establish the performances of the waste-based stabilizer when mixed with conventional stabilizer or partnerless. Borassus fruit ash and cement were used both in solo, and hybrid mix (5wt%, 10wt%) to stabilize termite mound soil in the mix design. The mix design was analyzed microstructurally with scanning electron microscopy (SEM)-energy dispersive spectroscopy (EDS) to understand the effect of each stabilizer on the microstructural level. Fourier transform infra-red (FTIR) was conducted to identify the functional group present in each mix design to establish the influence of both stabilisers on the bonding mechanism. The mix design was also tested for water sensitivity, linear shrinkage, and compressive strength. From the results, samples containing 10wt% hybrid borassus fruit ash/cement exhibited higher content of Silicon, Aluminum, and Iron consequently satisfactory compressive strength. For hybrid stabilisation of earth-based materials, preference is given to 10wt% stabilisation level. The results of this study are analyzed to reduce the footprint of agricultural waste and to model locally available materials into sustainable housing materials.

Ash content in fruit samples of the <i>Actinidia kolomikta</i> genetic collection

Among the representatives of the Actinidia Lindl. genus, Actinidia kolomikta (Siebold et Zucc.) Planch. is valued as the most winter-hardy variety with high taste and dietary properties. The Federal Horticultural Research Centre for Breeding, Agrotechnology and Nursery has a live collection of Actinidia, which includes more than a hundred cultivated forms and varieties. In this study, ash content in Actinidia kolomikta fruits of 10 varieties and collection samples was studied by energy-dispersive X-ray spectroscopy using an analytical scanning electron microscope JEOL JSM6090 LA. A decreasing series was established for the accumulation of ash elements in the fruits of the studied samples: Ca> K> P> Mg> Mo> S> Se> Zn> Fe> Co> Si> Na. In terms of accumulation of useful macro- and micronutrients, the most valuable varieties were identified. The total accumulation of macronutrients in the fruit ash ranged from 28.6 to 45.3 wt%. This indicator was the highest in the fruits of Dolgovechnaya, Uslada and Vinogradnaya (42.068–45.638 wt%). The fruits of the Uslada variety were distinguished by a high content of phosphorus (5.89), silicon (0.504), sulfur (1.34) and potassium (23.596 wt%). In terms of micronutrient accumulation, the Pamyati Kolbasinoj variety (4.904 wt%) showed the highest levels of molybdenum (3.804) and selenium (0.801 wt%). Iron accumulated more readily in the fruits of the Uslada variety (0.161), cobalt — in Nadezhda (0.157), zinc — in Vinogradnaya (0.247) and Chempion (0.195). A statistically significant positive correlation (r > 0.7) was revealed in the accumulation of the following pairs of ash elements: sodium — sulfur (r = 0.70), phosphorus — potassium (r = 0.75), silicon — iron (r = 0.76), as well as molybdenum with phosphorus (r = 0.84), sulfur (r = 0.83) and potassium (r = 0.71). A statistically significant negative correlation was observed only for the accumulation of phosphorus and calcium (r = -0.71). According to the results, the fruits of the Actinidia kolomikta varieties under study can be an additional or alternative source of dietary minerals in functional food products.

Fundamental and rheological properties of oil palm fruit ash modified bitumen

This study was conducted to investigate the suitability of using oil palm fruit ash (OPFA) as a bitumen modifier. The OPFA was used to fulfil all bitumen modification requirements, as well as to take advantage of a waste by-product of the palm oil mill industry which could help to reduce environmental pollution. Twenty-four OPFA-modified bitumens (OPFA-MBs) were produced by the laboratory mixing of normal bitumen (80/100) from two sources with Fine and Coarse OPFAs of six different contents. This process was conducted at a mixing temperature of 160°C, a mixing time of 60min and a mixing stirring speed of 800rpm. The consistency and rheological characteristics of the OPFA-MBs were analysed by means of conventional as well as dynamic mechanical analysis using dynamic shear rheometer (DSR), bending beam rheometer (BBR) and direct tension test (DTT). The results of the investigation indicate that binder compounded with OPFA becomes less susceptible to temperature, improve resistance to rutting at 70°C, fatigue cracking at 20°C, and thermal cracking at −17°C of the surface pavement temperature compared to the unmodified bitumen. The OPFA-MB can be categorised as a binder with penetration grade of 60/70 or as PG 70–16 in the performance based system. Finally, it can be deduced that it is feasible to use OPFA as a modifier of bitumen.
