So that it may be certain that a concrete specimen’s mechanical properties reach the strength and deflection imperatives for its intended use, concrete specimens with specific dimensions are prepared, ...

A shortage of skilled labor continues to be the dominate issue in the construction industry, and rightfully so. However, delays in construction schedules have always been a thorn in the side of ...

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 ...

Some basic NDT techniques utilized to assess concrete structures include:Once concrete has hardened, it is important to determine whether the final structure is suitable for its designated use. To do ...

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 ...

Maturity and compressive strength of concrete is tested through both destructive and non-destructive methods. Destructive test involve damaging some of an element or the structure. Some would like to ...

This latest accomplishment joins the company’s previously secured ASTM certifications, enhancing the features and expanding the end-uses for its microalgae-based bio-cement and bio-concrete. BOULDER, ...
