The performance-based service life model proposed by the European project DuraCrete, [10] and by FIB Model Code for Service Life Design, [11] is based on a probabilistic approach, similar to the one adopted for structural design. Environmental factors are considered as loads S(t), while material properties such as chloride penetration ...

Large crack-widths (greater than 0.3 mm) permit ingress of moisture and chemical attack to the concrete, resulting in possible corrosion of reinforcement and deterioration of concrete. Therefore, thick covers defeat the very purpose for which it is provided. There is a need for judicious balance of cover depth and crack width requirements.
Reinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility.
Introduced in 2004, the "hidden" fee has been increased over the years to a monthly charge of $3.49 per line. The complaint alleges the fee is disclaimed in the "Government Taxes and Fees" section ...
The U.N. General Assembly on Wednesday overwhelmingly called on the United States to end its decades-long sanctions regime on Cuba, as the communist-run Caribbean island nation suffers its worst ...
IBS is considered a very common disorder that affects between 10% and 15% of people in the U.S., per the American College of Gastroenterology. That means some 33 million to 51 million people are ...
A clear distinction is made between the ultimate state (US) and the ultimate limit state (ULS). The Ultimate State is a physical situation that involves either excessive deformations leading and approaching collapse of the component under consideration or the structure as a whole, as relevant, or deformations exceeding pre-agreed values.
