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 ...

Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

Extensive laboratory testing and data analyses reveal that the oil and gas industry can reliably estimate foamed-cement sample compressive strength, if the design engineer knows the compressive ...

Researchers from North Carolina State University have, for the first time, used a "micropillar compression" technique to characterize the micro-scale strength of cement, allowing for the development ...

Until the early 1970s, there was relatively little interest in measuring the compressive properties of composite materials. For design purposes, it was generally assumed that the compressive strength ...

For SAI tests, a cement additive product test is acceptable at a minimum strength of 75% of the control product strength. i For one Series B test, the Portland Cement control achieved a compressive ...
