Composites of polypropylene/Acylonitrile butadiene rubber/Rice husk powder/ (PP/NBRr/RHP) with and without trans-polyoctylene rubber (TOR) were prepared, and the effects of trans-polyoctylene rubber were investigated. By using rice husk powder of 150300μm, five different compositions of PP/NBRr/RHP composites (i.e.100/0, 80/20, 70/30, 60/40 and 40/60 phr) were prepared in an internal mixer at 180 °C and 50 rpm rotor speed. The results indicate that the incorporation of TOR improved the tensile properties of PP/NBRr/RHPcomposites. Scanning electron microscopy of the fractured surfaces proved that TOR promoted good adhesion between the PP-NBRr matrices and RHP.

Load-Displacement Behaviors of Reinforced Concrete Beam Embedded with Galvanized Steel Cable: Comparison Between Experiment and Finite Element Analysis

Lightning is a natural phenomenon which occurred when the upper atmosphere becomes unstable due to rising air currents. Lightning can be one of the natural causes of human injuries or damage to electrical equipment. In order to create a system to protect buildings from this natural phenomenon, the Lightning Protection System (LPS) was introduced. However, various problems have been associated with this conventional method. A common problem related to external lightning protection cables is corrosion. Therefore, the newly arrangement of lightning protection cable was proposed and investigated. Galvanized steel cable was used in this research due to suitability of the materials to be embedded inside reinforced concrete beam. Load-displacement behavior from the three (3) point flexural test was compared with the finding from the Finite Element Analysis (FEA). From the result, FEA showed slightly higher than experiment result at the maximum load.

The behaviours of steel fiber as main reinfocement in high performance slurry infiltrated fiber reinforced concrete

2013 , Mustaqqim Abdul Rahim , Zuhayr Md Ghazaly , Ragunathan Al Santiagoo , Shahiron Shahidan

Concrete is a structure that very weak in tension and need additional material to enhance their structural capacity. In 18thcentury, concrete have been recognized as structure that very weak in tension [. Thus, concrete need additional supporting material that can improve the tension capacity. Because of the steel is very good in tension, the steel bar was embedded in concrete at the tensile stress area to obtain the full capacity of the steel bar as reinforcement.

Concrete prisms are being test with flexural testing by different percentage volume of steel fibres. The total number of 24 prisms were made which contain 3 %, 6 % and 9 % of steel fibres respectively. This only consist experimental results. Specimens used in this study using a prism mold of 100 mm x 100 mm x 500 mm. Eighteen prisms will be added with a layer of 10 mm of steel fibre using slurry method. All of the samples were tested using flexural testing to determine the maximum loading. The highlight scope of this research is to evaluate the physical behavior of Slurry Infiltrated Fibre Reinforced Concrete in term of maximum load and cracking pattern. The results of the study were also compared with concrete without steel fibres. However, the workability of the concrete decreased as the number of steels fibre increase. The maximum load was obtained by the lowest percentage of steel fibre (3%).
