Elements of Theory of Elasticity (with solved examples) Introduction: Applications of the finite element method include elasticity problems also. Theory of elasticity deals with the stress and displacements in elastic solids generated by external forces. Some Important Aspects in theory of elasticity: Stress Components There are two types of stresses acting on each face of … Read more Elements of Theory of Elasticity (with solved examples)

IRC Method Concrete Mix Design

IRC method

IRC Method Of Concrete Mix Design About IRC 44-1976 Primarily implemented in the design of Concrete Rigid Pavements on Road Construction. Flexural strength is more often specified than compressive strength in the design of concrete mixes for pavement construction. Basic Differences from IS method Strength Criteria– Checking of Flexural strength have more priority than Compressive … Read more IRC Method Concrete Mix Design

High Performance Concrete & Self-Compacting Concrete

High Performance Concrete

High Performance Concrete Concrete may be regarded as high performance for several different reasons: high strength, high workability high durability perhaps also improved visual appearance. High strength concrete (HSC) might be regarded as concrete with a strength in excess of 60MPa and such concrete can be produced as relatively normal concrete with a higher cement … Read more High Performance Concrete & Self-Compacting Concrete

What are Properties of Hardened Concrete|Governing Factors

Bridge Pier Substructure

Properties of Hardened Concrete Properties of hardened concrete are explained on the basis of its Strength and Performance under various types of force actions and conditions. Main parameters that are used to define the strength of concrete are Compressive Strength: Compressive strength of concrete is usually defined as characteristic compressive strength (fcu / fck).
