The aim of this research is to determine the potential of geopolymer artificial aggregate as substitute for granite and limestone aggregates. Several aggregate property test such as aggregate impact test, aggregate crushing test, specific gravity test, water absorption test and the Los Angeles Abrasion test are done on the aggregates. The fly ash-based geopolymer artificial aggregate is produced through geopolymerisation by mixing fly ash with alkaline solution. The results show that the fly ash-based geopolymer artificial aggregate is lighter than natural aggregate in term of its specific gravity. The impact value and crushing value for fly ash-based geopolymer artificial aggregate are slightly higher compared to natural aggregate while the water absorption value is much higher compared to natural aggregate. Furthermore, the fly ash-based geopolymer artificial aggregate has higher value in the Los Angeles Abrasion. Overall, the fly ash-based geopolymer artificial aggregate can be considered as one of the construction materials in the roadwork pavement and in concrete as an alternative for coarse aggregate besides natural aggregate with more lightweight properties.

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 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.

2020-07-09 , Mustaqqim Abdul Rahim , Syazwani Karuddin A. , Afizah Ayob , Nur Aizat Ahmad A. , Shahidan S. , Salwa Mohd Zuki S.

The reinforced concrete beam with lightning protection cable used in this research to determine the stress intensity and crack pattern of the beam. In this research, commercially available software developed by ANSYS used to model the nonlinear behaviour of reinforced concrete beams. The beam will model by using the ANSYS parametric design language (APDL). The beam structure was modelling in 3D geometry with the reinforcement steel bar and lightning cable embedded in the reinforced concrete beam structure. The material uses to develop the beam are Grade 30 concrete and high yield steel for main reinforcement. The material for lightning cable used was galvanized steel iron, which is highly resistance to corrosion and oxidation. The beam model in simply supported with pinned support at two end of beam and three-point load is applied. From the result beam added with lightning cable at bottom can sustain a higher stress intensity compare to the beam without additional lightning cable and beams without lightning cable have developed largest crack compared to the beam with lightning cable.

This study focused on the reclamation of ash from incineration process and development of new artificial lightweight aggregate (LWA) that have comparable properties with existing natural coarse aggregate. The main objective of this study is to examine potential use of recycled municipal solid waste incineration (MSWI) ash as raw material in LWA production with a method of cold-bonded pelletization. Two types of incineration ash which is bottom ash (BA) and fly ash (FA) were collected from Cameron Highland Incineration Plant, Malaysia. The properties of BA and FA are studied by means of X-Ray Fluorescence (XRF) and microstructure of these ashes were inspected using Scanning Electron Microscope (SEM). The properties of BALA and FALA produced in this study is examined including loose bulk density, water absorption and aggregate impact value (AIV). From the results of both types of artificial LWA, the lowest loose bulk density of BALA is BALA50 with 564.14 kg/m3and highest is at 831.19 kg/m3. For FALA50, lowest loose bulk density is 573.64 kg/m3and highest is 703.35 kg/m3. Water absorption of BALA and FALA is quite similar with one another in with the value of 23.8% and 22.6%, respectively. Generally, FALA have better qualities of LWA comparing with BALA with lower bulk density and water absorption and can be categorized as strong aggregate. In summary, reclamation and reutilization of incinerator ash has generated acceptable qualities for artificial LWA. Both types of BA and FA shown a great potential to be recycled as additional materials in artificial aggregate production.

Technology in concrete is rapidly developing to improve the quality and properties of concrete. One of the many recycled materials is worn-out tyres. Currently, the use of tires is very widespread considering the use of vehicles that increase from time to time. Piles of discarded tires can cause a lot of damage to the environment. So, by using steel wire waste (SWW) as new fiber reinforcement in concrete and with the combination with carbon black (CB), it is hoped that, by doing this, not only it could improve the quality of concrete, but also preserves the environment. Therefore, the objective of this research was, to identify the properties of fresh concrete with the addition of SWW and CB, and also to investigate the physical and mechanical properties of hardened concrete, incorporating of SWW as additional fiber reinforcement and CB. For fresh concrete, workability using a slump test was conducted. Several tests were carried out on the properties of hardened concrete. Among them were compressive strength, flexural strength, splitting tensile strength, and water absorption. The physical appearance of the concrete has also been examined and recorded. There are four batches of concrete which consist of one control batch and three batches of concrete with various weights of SWW which are in the portion of 300 g, 600 g, and 900 g, and the weight of CB is maintained at 300 g for all batches. For workability, all concrete batches with the addition of SWW and CB show acceptable workability. For the case of the density of fresh concrete, samples containing 900 g addition of SWW have the highest density which was 2520 kg/m³, as expected. Results for water absorption show that the lowest value is contributed by the control sample which was 7.6%. For compressive and flexural strength, 300 g addition of SWW has the highest value which was 28.52 MPa for compressive strength and 7.52 MPa for flexural strength. Lastly, for splitting tensile strength, the highest value was also obtained when 300 g addition of SW was added which was 5.4 MPa. To conclude, SWW and CB can be added to concrete to obtain comparable strength of concrete. However, some modifications could be made to both recycle materials to improve concrete performance.

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%).

Use of natural fiber in concrete to enhance the strength of concrete have been used widely and become as part of an alternative building materials. For instance, the use of coconut fiber (CF) which are non-hazardous, environmental-friendly and can improves the engineering properties of concrete. The aim of this study is to identify the workability and density of CF modified concrete. CF were added into the mixture in 3 different amount that is 200 g, 400 g, and 600 g. The size of the cube samples is 100 × 100 × 100 mm and were cured for 14 days, and 28 days. To evaluate the effect of CF in improving the properties of concrete, the properties of ordinary concrete are used as a reference which consist 0% CF. The fresh and hardened densities for all samples also show that when more fiber was added into mixture, densities reduced. As summary, the study shows that by adding CF in concrete reduced the workability and density of concrete.
