Since most bridges contain multiple cantilever spans, we can use precast component to reduces the time required. The most important part is these bridges can tolerate the effects of thermal expansion and ground movement better than others. Consider Singapore’s weather, we need ensure that the bridge structure does not

    The composite concrete structures have been always a topic of major importance in the field of construction. The use of concrete in composite structures may be with steel sections in the form of steel-concrete composite sections, or with concrete cast at different times to form what is called concrete-concrete composite sections which are used in buildings and bridge constructions. Economic considerations indicate the desirability of composite action between the precast and the cast in place

    This general definition is happen to cover a broad concretes ranging in (14.40 to 18.50) kN/m3 and the cylinder compressive strength is more than 17.2 MPa. Lower concrete density may be indicated for non-structural applications. Many sorts of concrete fall inside this range: some are cellular concretes made of foam or foaming agents, some are made of LWA and some cellular concretes also contain lightweight aggregates. Other LWC may contain some normal weight sand.

  • Advantages Of Resin Transfer Moulding (RTM)

    1016 Words  | 5 Pages Resin Transfer Moulding (RTM) This process uses a two sided (halves) mould that forms both surfaces of a laminate. The lower side of the mould is made rigid while the upper side is either a rigid or a flexible mould. The two sides fit together to form a mould cavity. With resin transfer infusion the reinforcements are placed into the mould cavity and the cavities are clamped together. Resin is then pumped into the mould, infusing the reinforcement material in the process. Once the mould is
