Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

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, ...

Contractors need to know how to correctly evaluate the in-place strength of concrete so they can determine to proper time to remove formwork, backfill or open up a pavement to traffic. Concrete must ...

Concrete suppliers and contractors are sometimes accused of producing or placing low-strength concrete. While low-strength concrete does occasionally occur, many times reported cylinder strengths are ...

A Purdue University invention that could help reduce time and money spent on the construction and repair of concrete highway pavement and other structures has been selected as a finalist for an Edison ...

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 ...

Not only could the new process help sequester CO 2 from the ever-warming atmosphere, it also results in concrete with uncompromised strength and durability. "More interestingly, this approach to ...
