Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement which hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment fondu. .

Prestressed concrete is a method for overcoming concrete's natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete. Prestressing tendons (generally of high tensile steel cable or rods) are used to provide a clamping load which produces a compressive stress that balances the tensile stress that the concrete compression member would otherwise experience due to a bending load. Traditional reinforced concrete is based on the use of steel reinforcement bars, rebars, inside poured concrete. Video by Elecosoft plc: http://www.eleco.com/

Sometimes all it takes as little more rebar or a little more soil compaction and a little more concrete, to make a stairway that will last for many years.

Slump test or also known as slump cone test is used for measuring workability of concrete produced on site. It is one of the important field test in construction site. To more about this civil engineering process read: http://www.civileblog.com/workability-of-concrete/
Over the centuries, engineers and architects have devised ever-new ways to build taller, stronger and more beautiful creations using game-changing materials like steel girders, earthquake-proof foundations and glass curtain walls. But what does the future hold for construction technology? Will there come a day when noisy construction crews are replaced by swarms of autonomous nanobots? Will the cracks in concrete foundations one day miraculously heal themselves, or gas stations be replaced by electric cars running on self-charging roads? Watch our video on "10 Futuristic Construction technologies" for most exciting construction innovations of the near future. #construction #futuretechnologies #constructionvideos #constructionmaterials
The slump test is a means of assessing the consistency of fresh concrete. It is used, indirectly, as a means of checking that the correct amount of water has been added to the mix. The test is carried out in accordance with BS EN 12350-2, Testing fresh concrete.
The concrete slump test is an empirical test that measures workability of fresh concrete.The test measures consistency of concrete in that specific batch. It is performed to check consistency of freshly made concrete. Consistency refers to the ease with which concrete flows. It is used to indicate degree of wetness.
Are you looking for an efficient and open software for the calculation of buildings? Scia Engineer is the top calculation software in Europe for the calculation of structures. With thanks to the intuitive 3D graphical user interface, engineers can follow the current architectural tendencies en convert it to a realistic calculation model. The user can work at his own discretion with simple or more complex structures, and even import the architectural 3D mode through IFC. The complete integration and support of the Eurocodes and the IBC will guarantee a complete check according to the most recent rules and codes. To top it all off, there is also a personal engineering report available to create your documentation. During this webinar of 60 minutes, you will learn: - The modeling of a concr...
