Improving Durability of Asphalt Pavement Wearing Course Submerged in Water Using Candle Wax as Water Proofing Agent: An Assessment Using RSI, FDI and SDI
Abstract: Asphalt pavements are designed and constructed to meet mostly stability and durability requirements during its design life. However, durability of asphalt pavements also heavily depends on other physical parameters as good drainage facility apart from having good material mix and structural designs. In the wake of asphalt pavements not supported by good drainage measures it is very likely that these pavements will fail sooner than later. On this basis, the …

ANALYSIS AND DESIGN OF RECTANGULAR AND L-SHAPED COLUMNS SUBJECTED TO AXIAL LOAD AND BIAXIAL BENDING
Abstract: Next to rectangular and circular columns, L-shaped columns may be the most frequently encountered reinforced concrete columns, since they can be used as a corner column in framed structures. The behaviour of irregular shaped reinforced concrete columns has been a constant concern for a structural engineer, to design a safe and economic structure in modern buildings and bridge piers. L-shaped reinforced concrete column subjected to biaxial bending and axial compression …

Study on Analysis and Design in Reinforcement Structure Joints of Water Tank Structure for Safety Human life
Abstract: A water tank is used to store water to surge over the daily requirement. In the construction of concrete structure for the storage of water and other liquids the imperviousness of concrete is most essential. The permeability of any uniform and thoroughly compacted concrete of given mix proportions is mainly dependent on water cement ratio. The increase in water cement ratio results in increase in the permeability. The decrease in …

Structural Analysis and Design Considerations for Flyover Bridges
Abstract: AbstractBridges serve as essential components of transportation networks, facilitating the movement of vehiclesand pedestrians across obstacles, such as rivers, valleys, and roads. The stability of a bridge largelydepends on the strength and structural capacity of its deck slab. The deck slab must endure both its ownweight and the additional loads imposed by vehicles. A key aspect of bridge design is assessing theflexural stress acting on the deck slab to determine …

Structural Behavior of Bubble Deck Slab
Abstract: Concrete is dense, and 5% of the world’s CO2 is formed during the manufacture of the cement that goes into it. Then there is the aggregate that is dug out and the trucks that have to carry it. Not only, but the extreme amount of the concrete that is in a slab isn't even desired; it is just a spacer between the bottom, where the reinforcing steel is in tension, …

Field Assessment of Runway Pavement Surface Texture for Baghdad International Airport
Abstract: One of the major serviceability issues which reflects the suitability of the airport runway for serving international flights is the surface texture of concrete pavement. The concrete surface of the runway 33R-15L of Baghdad international airport is badly covered with large spots of aeroplanes tyre rubber. The international flight companies had claimed that the rough surface of the runway concrete pavement caused damage and deterioration to their aeroplane’s tyres. The …

Corrosion Protection of Rebar steel in Ocean Atmosphere
Abstract: Rebar is an important engineering metal. It is used in construction of housing, bridge and other infrastructures works. It is surround with concrete for strengthen building block components. The concentration of chloride ions in ocean atmosphere is higher so it produces hostile environment for rebar steel. The lots of porosities are available on the outer surface area of concrete so chloride ions enter inside by osmosis or diffusion process. It …

Study the Corrosive Effect of Greenhouse Gases on Metallic and Non-metallic Materials
Abstract: Carbon dioxide is a major corrosive pollutant for building materials. It enters inside materials by diffusion or osmosis process and in presence of moisture it produces H2CO3 which decrease the pH value and accelerates chemical and electrochemical reaction with building materials. The carbonation reaction produces deterioration inside and outside of building materials. It produces corrosion reaction with metallic bar and disbanding with concrete. CO2 reacts with Ca (OH)2 and Mg(OH)2 …

Efflorescence: Uninvited Mystery Guest
Abstract: Since the introduction of modern pigmented concrete products in the early1950’s, coloured concrete products have opened new possibilities in the field of building and landscape design and ironically to a new visible phenomenon called efflorescence. Unfortunately, despite careful selection of raw materials and conscientious compliance with the production parameters, colour changes of the finished products are always the enemy. Efflorescence is a deposit of salts, usually white, formed on a …
