    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%).

    Ultrasonic pulse velocity methods is one of the non-destructive testing methods. Commonly the compression test was used to determine the compression strength of concrete. Laboratory works had been carried out at heavy concrete laboratory to obtain the result for both non-destructive and destructive test. By using concrete cubes of sizes 100 x 100 x 100 mm and subjected to water curing for 7, 14, 21 and 28 days to obtained desire result for Ultrasonic Pulse Velocity and Compression test. Ultrasonic Pulse Velocity were initially done before the Compression test. The data obtained from each test has been evaluated and tabulated in this report. From this research, the variation between predicted strength and experimental strength for Ultrasonic Pulse Velocity testing was identified; the higher the pulse velocity, the higher the predicted strength and lower times passes by pulse velocity, the higher the predicted strength.

    The use of reinforced concrete flat slabs in building construction increases the floor-to-floor clearance, expedites site operations, and offers aesthetically rewarding features. However, punching shear failure in a flat slab is brittle in nature and can be potentially catastrophic. Many studies have been conducted to improve the punching shear capacity of flat slabs but some of the proposed punching shear reinforcements were complicated and costly. This research aimed to evaluate the effectiveness of a simple and cost-effective; truss-shaped punching shear reinforcement embedded in a 1200 mm × 1200 mm × 175 mm thick flat slab specimen. Three types of truss-shaped punching shear reinforcements were prepared. All specimens were supported at the edges and subjected to gravity load tests. The results showed that the introduction of truss-shaped punching shear reinforcement increased the punching shear capacity in the range of 7.71% to 21.47%. The maximum deflection of these specimens exhibited an insignificant increase compared to the control specimen, suggesting that punching failure governed the ultimate behavior. The additional strength offered by truss-shaped punching shear reinforcement makes flat slabs as a construction material more appealing because they allow them to withstand higher design loads.

    Since the cost of cement increases and the pollution to environment due to greenhouse effect are becoming more serious year by year, thus, dolomite fines subjected to replace the cement in concrete mix as it has lower cost compared to cement and it is obtain directly from the Earth ground without any manufactured process. Dolomite fines also shows almost similar physical and chemical properties as cement. The various replacement of cement with dolomite fines carried out in this study is 0%, 5%, 10%, 15% and 25%. The grade of concrete sample designed to be 30. The properties of concrete sample in terms of physical characteristics; slump, density and water absorption for various percentage replacement are determined in this study. In this study, it shows the dolomite fines are lightweight aggregate compared to the cement and the water absorption of is lower compare to that of the control concrete.

    This research focuses on the chemical properties of coal fly ash (CFA) and coal bottom ash (CBA) obtained from Sultan Azlan Shah Power Plant and compares them with the characteristics of ordinary Portland cement (OPC). Coal has been recognised as a significant fuel source in Malaysia, where it is extensively employed in the creation of steel, cement, and power. When coal is burned to create power, several different types of coal ash are created, including fly ash, bottom ash, boiler slag, and clinker. Fly and bottom ash, however, are the main coal ash waste products that have been created. In an effort to create sustainable concrete from waste, a number of studies have been carried out to ascertain the chemical characteristics of fly and bottom ash. These tests include Energy Disperse X-Ray (EDX), Mineralogy (XRD), and X-Ray Fluorescence (XRF). From the SEM result, fly ash has smaller particles and a spherical, uniform shape than bottom ash and cement. Fly and bottom ash from the Sultan Azlan Shah power plant contain a number of elements, including Silicon (Si), Aluminium (Al), Oxygen (O), Calcium (Ca), Titanium (Ti), Iron (Fe), Magnesium (Mg), Potassium (K), Carbon (C), and Sodium, according to Energy Dispersive X-Ray (EDX) test. The fly ash is primarily an amorphous material, with the presence of quartz crystalline phase (SiO2) at 24.3% and bottom ash at 31.1%, according to X-ray Diffraction (XRD) data. For the mullite phase (3AlO3.2SiO2), fly and bottom ash show results of 24.9% and 14.5%, respectively. According to an X-ray fluorescence (XRF) investigation, the main constituents of fly and bottom ash are silica, iron, and alumina. Fly ash is classified as Class F because it has a high concentration of SiO2, Al2O3, and Fe2O3 while OPC has a high CaO value. With the right composition and material preparation, CFA and CBA from the Sultan Azlan Shah Power Plant can be used as a cement replacement in concrete.

    Concrete is the most consumed material, with three tonnes per year used for every person in the world. Twice as much concrete is used in construction as all other building materials combined. Concrete has excellent characteristic in compressive strength, but low in tensile strength. Steel commonly used in reinforcing material because of high tensile strength. The usage of steel as reinforcing material is limited because it is costly and also has an effect on air pollution during its manufacturing process. As an alternative to overcome this problem, bamboo material has been used as a replacement of reinforcement in concrete. Bamboo is a suitable material because it is a natural material, cheap and also available material. In this research, the performance of bamboos as an alternative material in reinforced concrete has been evaluated. Tensile strength test of bamboos has been performed to identify the yields stress of bamboos. From the test, result has shown that bamboo has a similar characteristic with steel and bamboo can be used as an alternative material for reinforcing concrete. However, the characteristic of bamboos showed high water absorption and low bonding strength between bamboo's surface and concrete. In this research, a waterproofing agent has been used to minimize water absorption and increase the bonding strength. Flexural strength test of the bamboo singly reinforced beam with the size of 150 mm x 150 mm x 750 mm has been undertaken to determine the performance of bamboo as reinforcement. From the test, it has resulted that bamboo give good potential as an alternative material in concrete reinforcement for low-cost housing industry.

    The research carried out to study on the performance of the flat slab under the design load. The design loads consist of service load, 14.68 kN/m2 and the ultimate load, 21.31 kN/m2. The justification on the design load was from the car park. The Three-Dimensional (3D) Finite Element Analysis (FEA) were conducted to investigate their failures modes with the appropriate modelling of element, mesh and concrete parameter. The size of flat slab was 1200 mm x 1200 mm x 175 mm while the material parameters were the Grade 25 for concrete and S275 for steel. It is found that the improvements more than 20% to the strength of model flat slab with shear reinforcement. Another outcome of the study indicated that the punching shear location using the FEA was less than 250 mm from column perimeter which is within the two times the depth (2d) from column face as proposed by the Eurocode 2: Design of Concrete Structures.
