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 ...

Researchers have, for the first time, used a 'micropillar compression' technique to characterize the micro-scale strength of cement, allowing for the development of cement with desirable strength ...

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 ...

This image shows a representative cement micropillar sample imaged by scanning electron microscope. Samples like this one are key to the use of a 'micropillar compression' technique to characterize ...

President, Wyoming Test Fixtures Inc. Because composite structures are subjected to flexural loading in typical applications, it is not surprising that flexure testing of composites is commonly ...
