Concrete is an essential construction material that is used globally. Combining coring and rebound surveys provides the most efficient and cost-effective method of assessing in situ concrete strength, ...

Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...

When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...

Not all damage to a load-bearing structure is immediately apparent. So how do civil engineers find out that a bridge or a large hall is no longer safe? Many clues form a picture. Concrete structures ...

American Association of State Highway and Transportation Officials’ Committee on Materials and Pavements approves Purdue-invented method as a national standard for estimating concrete strength WEST ...

If structural engineers have their way, building codes will take a leap forward in the next couple of years to allow the use of higher-strength 80-ksi reinforcing steel in concrete shear walls in high ...

DENVER (CBS4)-- A consultant hired by the City of Denver has generally given DIA's concrete passing grades, but has recommended concrete testing at the airport be expanded from the terminal to the ...
