J.J. Brooks, in Concrete and Masonry Movements, 2015 Poisson's Ratio The term Poisson's ratio, μ, has been defined on p. 61 as the ratio of lateral strain to axial strain. Below approximately 30–40% of the ultimate stress, Poisson's ratio is approximately constant but, at higher str...
1.2 What is Poisson’s ratio, and where can it be of significance in concrete work? 1.2 ¿Qué es la relación de Poisson y dónde puede ser importante en trabajos con concreto? Literature Some materials known as auxetic materials display a negative Poisson’s ratio. Algunos materiales...
A concrete composition having a 28-day design compressive strength of 4000 psi and a slump of about 5 inches is optimized to have high workability and a high strength to cement ratio. The concrete composition contains about 375 pounds per cubic yard hydraulic cement (e.g., Portland cement),...
PROBLEM TO BE SOLVED: To provide a low yield-ratio high tensile-strength steel capable of obtaining high strength and a low yield ratio simultaneously with excellent weldability and low temperature toughness, and to provide a method for producing the low yield-ratio high tensile-strength steel.收藏...

applications, an optimal PNF waveguide would consist of 5 to 9 ridges, that is, with periods of 5 to 0.5 μm (Ref. 38), propagation distances from a few hundred μm to a few millimeters and an AR of at least 10, but concrete applications will lead to concrete geometries and ...
load values are plotted on a graph and corrected following the procedure specified in the test standard. Corrected stress values from penetration depths of 0.100 and 0.200in (2.54 and 5.08mm) are divided by standard stresses of 1,000psi (6.9mPa) and 1,500psi (10.3mPa), then multiplied by ...
