(c) 5-ply applies to plywood with 5 or more layers; for 5-ply/3-layer plywood, use values for 4-ply plywood. (d) Strength axis is defined as the axis parallel to the face and back orientation of the grain (veneer), which is generally the long panel direction, unless otherwise marked.

Get PriceThe 3, 5 or 7 day compressive breaks are not necessarily indicators for the 28 day breaks. If the material falls apart when removing the test cylinder, it is mostly likely excavatable or removable. A Performance Specification Option: Maximum 200 psi compressive strength (at 28 days)

Get PriceCompressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.
