Shear Strength Of Oil Palm Shell Foamed Concrete Beams, Hilmi Mahmud
Shear Strength Of Oil Palm Shell Foamed Concrete Beams, Hilmi Mahmud
Hilmi Mahmud
Four reinforced oil palm shell foamed concrete (OPSFC) beams were fabricated, and their shear behaviour was tested. The OPSFC has a target density of approximately 1600 kg/m3 and a 28-day compressive strength of about 20 MPa. Two beams were cast with shear reinforcements while the other two were cast without such reinforcements. For comparison, four reinforced normal weight concrete (NWC) beams were also cast. The beams that contained shear links failed in flexure mode, while those without links failed in shear mode. The experimental results indicated that the shear capacities of OPSFC beams without shear links are higher than those …
Material Aspects For High-Strength High Performance Concrete, Hilmi Mahmud
Material Aspects For High-Strength High Performance Concrete, Hilmi Mahmud
Hilmi Mahmud
The merits of high-strength high performance concrete (HSHPC) depend on the quality of constituent materials. The constituent materials play the vital roles to improve the performance of HSHPC. In particular, the use of supplementary cementing materials is essential when high strength and durability become the most critical issues to be considered for concretes. The addition of high-range water reducer and air-entraining admixtures are also inevitable to achieve good workability and freeze-thaw durability, respectively. This paper discusses various aspects of the major component materials of HSHPC. It briefly describes the property requirements of the component materials and emphasizes their contents or …
