Influence of Weight Fraction on the Average Crystallite Size of Hybrid ZnO/Al2O3 Supported Bio-Waste Activated Carbon Composites

Onuoha David Chikaorama*, Egbe Evudiovo Apha Peter, Abdulrahman Asipita Salawu, Abdulkareem Ambali Saka

Due to the inherent high surface energy and the multifaceted interaction between them and the matrix interface, metal  nanoparticles tend to coalesce in the absence of repulsive forces provided by a capping agent. It is therefore imperative  to provide a support system that will moderate the spatial behaviour of the particles to prevent the formation of bulk  particles a...

Electrochemical Impact of Zinc-Magnesium Oxide-Cellulose Nano-particle Electrodeposited Composite Coatings on Low Carbon Steel in Sodium Chloride Media

Benedict Uche Anyanwu*, Owoeye S.O., Olamide O.O, Olaitan K.L, Anibaba A.D, Yussouff A.A, Okpako O

Low-carbon steel (LCS) is applied in numerous engineering applications, such as construction, automobile  manufacturing, and product and component manufacturing, due to its unique mechanical properties. They are readily  available, hence are very cost-effective when considered in any application. However, they are usually affected by  corrosion when exposed to chloride-i...

Parametric Study on Bamboo Fibre Reinforced Polyester Composites: Role of Soaking Time, Catalyst Ratio, and Alkali Treatment

Adebisi A. A*, Adeleke S. A, Sudi S. D

Bamboo fibres were treated with varying conditions of soaking time, accelerator/catalyst ratio and NaOH treatment  concentration. These parameters play a major role in determining the performance properties of the developed polyester  composite for structural applications. The reinforced 10 – 40 wt% bamboo fibre–polyester composites were fabricated  using the hand layup te...

Development of Granite-Filled Recycled LDPE Composites for Lightweight Military Helmet Applications

R. M. Dodo*, I. I. Abubakar, Bello K. A., Z. Musa, B. A. Kusimo

The development of a lightweight military helmet using granite particulate (GTP) reinforced recycled low-density  polyethylene (RLDPE) was studied in an attempt to produce a light helmet with high strength and cost-effective material  for military applications. This study utilised the abundant presence of granite in the ecosystem. The granite stone was  washed using dist...

Evaluating Concrete Strength Properties with Waste Glass as a Partial Replacement for Various Coarse Aggregate Gradings

Ogunsina Emmanuel Seun*, Hamza Ahmed Adavize, Saka Ahmed Olalekan, Adebayo Lawrence Omoniyimi, Oluwaseun A. Adetayo

The reuse of waste glass in concrete production is an attractive option for achieving waste reduction and preserving natural resources from further depletion, thereby protecting the environment and promoting sustainability. This present study examined the variation in the strength properties of concrete using waste glass aggregate (WGA) as a partial replacement for diffe...

Evaluating the Effectiveness of Using Coconut Shell as Coarse Aggregate for Self-compacting Lightweight Concrete

Ogunsina Emmanuel Seun*, Ayeola Oluwafemi Michael, Morakinyo Abayomi Bright, Oluwaseun A. Adetayo

This study investigates the structural properties of concrete when coconut shell is used as a partial replacement for coarse aggregate. The objective is to evaluate the effect of this replacement on workability, compressive strength, and flexural strength of concrete. Mix designs were prepared by replacing conventional coarse aggregate with coconut shell at varying perce...

Effect of Nanoclay Loading on the Hardness Property of Epoxy Composites

Egere B.C*, Yusuf L.O, Abdulkadir Suleiman Abdulrahman

This study examines the influence of nanoclay loading on the hardness properties of epoxy composites. Nanocomposites were fabricated using varying weight percentages of nanoclay and epoxy via the hand layup method with an open mould. Mechanical characterisation was carried out using a Rockwell hardness tester, while the dispersion and morphology of nanoclay particles within the epoxy matrix ...

Physical and Mechanical Properties of Filler Loading on Low- Density Polyethylene/Doum Fibre Composite

Abdulkadir S. A*, Wakala B, Okpanachi C B, Muktari S, Egere B.C, Yusuf L.O

This study investigates the physical and mechanical properties of low-density polyethylene (LDPE)/doum fibre composites with varying filler loadings. Six composite samples were fabricated using a metal mould of dimensions 120 × 120 × 3 mm, with LDPE and doum fibre mixed in ratios of 100:0, 90:10, 80:20, 70:30, 60:40, and 50:50. Processing was carried out at 120 °C for 5–10 minutes. The prepa...
