Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...

The use of the non-destructive testing methods for determining the compressive strength of high performance concrete ensures high quality. Compressive strength test results are mainly used to ...

Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

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 ...

7-day strength: 3,428 psi 28-day strength: 4,449 psi (11% increase over design) 56-day strength: 4,974 psi (24.35% increase over the 4000 PSI design. The Argo graphene additive mix consists solely of ...

Concrete has quietly become one of the planet’s biggest climate problems, yet it remains the backbone of modern cities and infrastructure. A new class of graphene concrete is starting to change that ...
