Recessed can lights are a popular choice for modern homes, offering clean sightlines and even illumination. But these fixtures create a problem for builders and homeowners alike: every can light installed in a ceiling is a hole in the building envelope. When you add insulation and air-sealing to the attic or ceiling assembly, those holes […]
Concrete placement is an important process in the construction that determine the success of the structure and its life. Technical and environmental conditions are taken into strict consideration w
Corrosion of steel bars is highly detrimental for reinforced concrete elements and might undermine their serviceability and even cause structural failure. However, various precautions can be taken
Why Concrete Cracks? Generally, it is assumed that cracks are due to some problems in the foundation, whereas it is not always correct and should not be considered failure of structure or improper
In prestressed concrete structures, prestress is introduced by stretching steel wire and anchoring them against concrete. Therefore, the prestressing systems should comprise essentially a method of
Compressive stresses is induced in prestressed concrete before it is put to its actual use. Principles and advantages of prestressed concrete is discussed.
Geopolymer concrete has been employed in many applications for example earth retaining structures and water containing structures. Properties of geopolymer concrete with low calcium fly ash is disc
Poisson’s ratio of concrete is the ratio of transverse strain to longitudinal strain in concrete specimen subjected to axial loads. The longitudinal strain and vertical strain are produc
Modulus of elasticity of concrete(Ec) is defined as the ratio of the applied stress to the corresponding strain. Not only does it demonstrate the ability of concrete to withstand deformation due to
Modulus of elasticity of concrete is the ratio of the stress to the strain of the concrete under the application of loads. It is one of the very crucial properties of concrete that gets affected wi
