Thermal Integrity Profiling (TIP) is a non-destructive testing method used to evaluate the integrity of concrete foundations. It is standardized by ASTM D7949 - Standard Test Methods for Thermal Integrity Profiling of Concrete Deep Foundations. The testing method was first developed in the mid 1990s at the University of South Florida.
Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, [2] A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often ...
Concrete longevity [ edit ] Sodium acetate is used to mitigate water damage to concrete by acting as a concrete sealant , while also being environmentally benign and cheaper than the commonly used epoxy alternative for sealing concrete against water permeation .
division 17 - master format related specs, nonconforming to the above csi sections All spec divisions higher than 16 are placed in Division 17 - Others. Also use Division 17-Others for any spec-shaped material not easily classified (e.g., geotechnical, pre-bid notes, etc.)
"50 Divisions" is the most widely used standard for organizing specifications and other written information for commercial and institutional building projects in the United States and Canada. [5] Standardizing the presentation of such information improves communication among all parties.
TO-252, also known as DPAK [1] or Decawatt Package, is a semiconductor package developed by Motorola [2] for surface mounting on circuit boards. [3] It represents a surface-mount [ 4 ] variant of TO-251 package, and smaller variant of the D2PAK package.
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
Logo of Eurocode 2 An example of a concrete structure. In the Eurocode series of European standards (EN) related to construction, Eurocode 2: Design of concrete structures (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy.
