استحکام کششی, or σa, is the maximum tensile strength that a material can withstand before it breaks apart. It is calculated using the formula σa = kε^2 x V, where ε is the Young’s modulus of elasticity and V is its volume.
(بتن با عملکرد بالا با مقاومت کششی Psi چیست؟)
در بتن, psi (pounds per square meter) is the weight per square inch that concrete provides in the load of one unit area under normal conditions. It represents the pressure applied to the concrete surface and is used as a measure of the structural integrity of concrete materials.
psi high performance concrete refers to concrete that meets or exceeds the given psi values for a specific application. This means that the concrete has been tested at these high pressures and conditions to ensure its stability and durability.
The stories behind psi high performance concrete include the construction of buildings that required high pressure systems due to the extreme climate conditions they faced. به عنوان مثال, the spangled concrete used in the construction of the transatlantic was tested to meet these high pressures at sea level, allowing the project to safely move forward.
Another example is the use of psi high performance concrete in wind-till structures, which were designed to withstand strong winds and horizontal movement. The supports of these structures were designed to be able to resist even the greatest forces and thus prevent them from collapsing.
به طور کلی, psi high performance concrete offers several benefits over traditional concrete, including increased prestability, greater resistance to stress, and better seismic and fire tolerance. It is an important factor in the selection of building materials, as it helps to ensure the long-term health and safety of structures.

در نتیجه, psi high performance concrete is a highly advanced type of concrete that meets or exceeds the given psi values for a specific application. Its increasing prestability, greater resistance to stress, and better seismic and fire tolerance make it a popular choice for a variety of applications. By choosing psi high performance concrete, you can help to ensure the long-term sustainability and longevity of your infrastructure.
