Admixtures used in Concrete Admixtures are the substances which are added in the concrete in addition to its ingredients to enhance its performance.
Substructure Substructure or foundation is a part of the structure, usually placed below the ground surface and transfers the load to the underlying soil or rock. Differential settlement
Short Columns Columns in which the strength is governed entirely by the strength of materials and the geometry of the cross-section are called short columns. Short columns mainly carry compression loads. They are generally used in construction.
Component materials: Component materials required for cement making are Limestone, shale, slate, clay, chalk – Lime (60%), silica (20%), alumina (10%).
Elastic Modulus of concrete: The modulus of elasticity or “Young’s Modulus” is defined as the slope of the stress-strain curve within the proportional limit of a material. For a concrete
Sources of moment in columns: Bending moment in column arises due to different reasons:
Procedure of structural design: Structural design is said to be a uniform arrangement of the structural members and their sizes
