1. A STUDY ON THE MODIFICATION, CHARACTERISATION AND APPLICATION OF COCONUT WASTES AS FILLERS IN RUBBER COMPOUNDING
ABSTRACT
In this study, coconut palm wastes were obtained, washed to remove sands and debris and then dried at 95oC for 1 hr to remove surface moisture. Filler modifications through carbonisation were done at varying temperatures of 300oC, 400oC, 500oC, 600oC and 700oC....
2. DEVELOPMENT AND CHARACTERISATION OF EPOXY/BORASSUS PALM (Borassus aethiopum Mart.) LEAF STALKFIBRE REINFORCED COMPOSITE
Excerpt from the Study
This work was aimed at developing and characterising epoxy/BPLSF reinforced composite by hand lay-up method.At the end of the study, the following conclusions were made.
i. Characterisation of untreated and treated fibre confirmed the et...
3. EFFECTS OF FIBRE HYBRIDIZATION ON THE PROPERTIES OF NATURAL FIBRE FILLED EPOXY COMPOSITES
ABSTRACT
The problems of low mechanical properties of composites reinforced with fibres of natural origin have been a source of concern for researchers. Also, the insufficient utilization of bagasse fibres due to its moderate strength has further reduced its potentialities in composite...
4. EFFECT OF DATE SEED POWDER FILLER ON PROPERTIES OF HIGH-DENSITY POLYETHYLENE
ABSTRACT
High-density polyethylene composites of date seed powder were prepared at filler loadings of 0 to 40wt%. The particle sizes of the date seed powder investigated were 72, 125, 150 and 180µm. Calcium carbonate was used as a reference filler. The high- density polyethylene c...
5. OPTIMUM DESIGN OF THE THICKNESS OF CARBON FIBRE REINFORCED POLYMER MATERIAL (CFRP) REQUIRED FOR STRENGTHENING OF DEFICIENT REINFORCED CONCRETE BEAM
Abstract
A Carbon fiber-reinforced polymer (CFRP) has emerged as promising material for rehabilitation of existing reinforced concrete structures. However, one of the major concerns of using this material is its high cost. In this research, a classical optimization technique was employe...
6. SYNTHESIS, FORMULATION AND CHARACTERIZATION OF PHENOL FORMALDEHYDE/CHITOSAN COMPOSITES
Abstract
The methodology of the experiment involves three main stages. The first part describes the synthesis of the PF (novolac) resins. Novolac (resins) were prepared with an excess of phenol over formaldehyde under acidic conditions. PF molar ratio were varied from 1P:2F to 1P:8F. Th...
7. ASSESSMENT OF THE IMPACT RESISTANCE BEHAVIOUR OF RHA BASED KENAF FIBROUS CONCRETE
ABSTRACT
Waste materials utilization is one of the central concerns of waste management approaches in recent years. The developments in cement and concrete technology towards the production of sustainable concrete by using waste materials and cellulosic fibre is gradually attaining acce...
8. EFFECT OF VERTICAL RECTANGULAR OPENINGS ON THE FLEXURAL STRENGTH OF REINFORCED CONCRETE BEAM
ABSTRACT
Effect of vertical rectangular openings on the flexural strength of reinforced concrete beam is presented. Twelve reinforced concrete beams of dimension 200m x 230mm x 700mm with different sizes of rectangular openings, 25mm x 35mm, 50mm x 60mm and 75mm x 85mm which are placed...
