Extract of sample

During this the water chemically bonds with the cement and hydration takes place. The ultimate strength of concrete is a factor of water cement ratio and this is the reason a precise mix ratio of concrete is calculated and mix design is prepared. Finally the dry components are combined to form hardened matrix. This final product, the concrete is good in compressive strength but weak in tensile strength. To finish this weakness we provide steel reinforcement which has high tensile strength. This concrete is called the reinforced concrete. The concrete’s quality is determined by the quality and care taken while the production phase of the concrete. As we are well aware of the fact that elasticity of concrete is all most the same at low stress levels but tends to decrease as the higher stress levels are attained as matrix cracking develops. At the very same time the concrete is very weak in thermal expansion and has a low value of coefficient of thermal expansion. The content of cementitious material, along with the water content determine the final strength, durability, abrasion resistance, shrinkage values and many other properties. But the most important property that is under discussion is the Durability of concrete. ...

Seismic Response of Reinforced Concrete Frame Buildings with Different Ductility Classes Using EC8 and EC2
The concept of reinforced concrete was first initiated in Japan during the 1950s. However in the initial times, the use of the RC buildings was not considered as significant, a situation that has modified in the present times (Aoyama, 2001, pp.1-2). Considering natural calamities like the earthquake, it is essential that the constructed buildings are based on such materials that are capable of…

Steel fibre reinforced concrete
Two-point load test was used to examine the bending moment of the bars while the cubes were subjected to compression tests for estimating their compressive strength. The flexural strength was also quantified. The effects observed on the steel fiber and steel bar reinforced beams and cubes were compared with those of beams and cubes made with plain concrete. The observations and comparisons are…

How to achive sustainable concrete
Therefore, all human activities should be sustainable such that they ensure correct use of the resources available (without waste) as well as ensuring that the environment is conserved. One such activity that should be sustainable in nature is the production and use of concrete. Concrete has been one of the most important materials in the construction and infrastructure industry for more than 2000…

recycling of concrete
In as much as concrete is useful for various construction activities, it makes a huge percentage of the clutter found in landfills. In other words, most of countries generate construction and demolition waste (C&DW) and a bigger proportion of the waste are concrete. There is considerable regional difference because of the construction traditions, thus, the amount of concrete in C&DW ranges between…
