Sprayed Concrete for Repair of Structures Sprayed concrete can be defined as mortar or concrete pneumatically projected into place’. Sprayed concrete is used widely in the repair of deteriorated structures, because of its ease of application in situations where it is virtually impossible to use formwork to recast, and because it can be applied in … Read more
Underwater Construction Underwater construction is a method on how to place the concrete underwater. During the construction of bridges, dams or any structure where the foundation is most likely to lie underwater, the underwater construction is opted. Construction in water poses many difficulties especially in the places where the depth is considerable. During underwater construction, … Read more
Introduction to Artificial islands An artificial island is an island constructed by man rather than created by natural means. They are constructed by expanding the existing islets and by construction on existing reefs or merging some natural islets into a bigger island. Artificial islands are usually constructed by land reclamation. Land reclamation is a process … Read more
Weather Resistant Steel Weather resistant steel is a low alloy steel. Different from ordinary steel, weather resistant variant steel forms a protective oxide film called ‘patina’ in a appropriate environment. This oxide layer seals the surface and reduces corrosion loss. Weather resistant steel is also referred as weathering steel in market. This type of steel … Read more
Shear Connector A Shear connector is a steel projection provided on the top flange of steel composite bridge girders to provide necessary shear transfer between the steel girder and composite slab to enable composite action. The most widely used form of shear connector is the headed stud, or shear stud. Other forms of shear connector … Read more
What is Striking Formwork? The process of removal of formwork or shuttering in the process of casting concrete is known as striking. Once the concrete has achieved the initial recommended strength, to support the self-weight and any imposed loads, the shuttering is removed for further curing. Soffit forms are usually left in place for longer … Read more
Geologic Mapping Generally, geologic mapping starts from the preliminary studies phase with gathering of existing maps and data to detailed site-specific construction mapping. Types of maps progress from areal mapping to site mapping to construction (foundation specific) mapping. Areal mapping. An areal map should consist of sufficient area to include the project sites as well as … Read more
What is Formwork? Formwork by name means “The Mold” which means it is the casing into which the casting material, usually concrete, is poured to obtain the desired structural shape. In construction industry formwork is similar to a mold to cast concrete member in different shape and sizes using different types of materials such as … Read more
