Concrete in Compression (ACI 318)

July 12, 2017 TeamCivil Concrete, Concrete Design, Properties, Structural

Concrete in Compression It is generally accepted that the behavior of a reinforced concrete member under load depends on the stress–strain relationship of the materials, as well as the type of stress to which it is

Concrete in Tension: Tensile Strength of Concrete

July 11, 2017 TeamCivil Concrete, Concrete Design, Properties, Structural

Concrete in Tension: Tensile Strength of Concrete The tensile and compressive strengths of concrete are not proportional, and an increase in compressive strength is accompanied by an appreciably smaller percentage increase in tensile strength. According

Structural Design and Limit States

July 10, 2017 TeamCivil Concrete Design, Structural

Structural Design and Limit States Aims and methods of design Codes state that the aim of design is the achievement of an acceptable probability that the structure will perform satisfactorily during its life. It must

Compacting Factor Test

July 8, 2017 TeamCivil Concrete, Tests

There is no generally accepted method of directly measuring the amount of work necessary to achieve full compaction, which is a definition of workability. Probably the best test yet available uses the inverse approach: the

Flow Table Test

July 7, 2017 TeamCivil Concrete, Tests

Flow Table Test This test was covered by BS 1881 : 105 : 1984. The test is appropriate for concrete of high and very high workability, including flowing concrete which would exhibit a collapse slump.

Cement Manufacturing Process

July 6, 2017 TeamCivil Concrete, Materials

Cement Manufacturing Process History of Cement: Cement is a material which is highly compatible to the earth’s eco-system and most adaptable to sustainable development. Cement is a fine powder which sets after a few hours

Mechanisms of Concrete Confinement

July 6, 2017 TeamCivil Concrete Design, Structural

Mechanisms of Concrete Confinement Concrete under uniaxial compression tends to expand laterally and the longitudinal strains generated by such loading give rise to transverse tensile strains. which cause vertical cracking and failure in concrete. Lateral

Cracking In Concrete Walls: Causes, Types and Mitigation

July 6, 2017 TeamCivil Repair

Cracking In Concrete Walls Cracks in concrete walls and slabs are a common occurrence. They appear in floors, driveways, walks, structural beams, and walls. Cracking can not be prevented but it can be significantly reduced
