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/
Recommended Engineering Books http://amzn.to/2xnwjRg 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 #constructionmateria...
Bleeding is one form of segregation, where water comes out to the surface of the concrete, being lowest specific gravity among all the ingredients of concrete. Bleeding can be easily identified in the field by the appearance of a thin layer of water in the top surface of freshly mixed 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.

This video show how to efficiently manage the form works during the construction of buildings or structures. WTF aluminum formwork is a rapid paced construction system for forming cast in place concrete structures. WTF provides aluminum formwork for reinforced concrete construction of single and multi-story buildings and enables the walls and slab to be placed monolithically in the same operation. This increases efficiency, and also produces an extraordinarily strong structure with excellent concrete finish.

How to Calculate Cement, Sand and Aggregate Quantity in Concrete This is most common method to calculate material requirement for cement concrete. In this tutorial, you will learn the process of I have made the steps and I have calculated the quantity of materials. I will explain you it in detail. The volume of PCC to be done is considered as 10 cubic meter which is to be done with M15 grade of concrete whose proportion is 1:2:4.

This video walks through checking and validating a structural concrete beam through hand calculations. The shear and moment diagrams are calculated and are compared to the results from Robot (3:18). The moment forces calculated are used to make a preliminary estimate of the required area of steel for flexure utilizing the previously discussed rules of thumb (7:20). Finally, the shear reinforcement is designed by referencing ACI Design Handbook for Design of Structural Reinforced Concrete Elements in Accordance with ACI 318-05, Figure 2.71 (9:50).

https://goo.gl/KDThpo Learning concrete does not need to be boring. My new iBook covers all the different aspects of concrete engineering (including history of concrete, constituents of concrete, properties of fresh and hardened concrete, mix design, durability of concrete structures, sustainability of concrete) in an engaging way using the power of iBook. Photographs of real life structures and illustrations are widely used throughout the book to aid learning and also to give context to the materials presented. Interactive quizzes makes the readers engaged and help deep learning.

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.

Erik Schlangen is Professor "Experimental Micromechanics" and director of the Microlab at Delft University of Technology, faculty of Civil Engineering and Geosciences. The main research topics of his chair consist of studying mechanical properties of materials to be able to understand failure mechanisms and to develop materials with improved properties. A further focus of his research is the field of chemo-mechanics which tries to study degradation due to coupled chemical and mechanical actions in materials. In 2005 he was amongst the first to develop new materials with self-healing properties. He took the initiative in developing self-healing concrete using Bacteria and he was the inventor of the self-healing Asphalt using steel-wool fibres and induction energy. He obtained a MSc-degr...
