    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.

    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.

    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.
