Inversion procedures were defined and tested on two industrial structures. They rely on the consistency of non destructive measures or on data obtained from destructive testing. We present methods and results, the selection criteria and the approach adopted for operation. Ours propositions are written ...
When testing concrete on site, a decision must be made about how many cube failures can be accepted before deciding to improve the mix; probably by adding more cement. The second example is presented in Section 13.6. When designing a structure, the durability can be calculated from a number ...
The performance of concrete exposed to marine environments: predictive modelling and use of laboratory/on site test methods This paper reports an approach by which laboratory based testing and numerical modelling can be combined to predict the long term performance of a range of...

The pull-out post-insert method used for testing high-strength concrete strength is studied with the pull-out testers of ring-type stabilizer and three-point stabilizer.On the basis of the experiment research,the relationship of the pulling resistance and compressive strength of high-strength concret...
On Site Moisture Testing with FloorMedics 24 Hour Emergency Test In this video, our lead tester and company owner Ryan Fortune heads out to a job site.Wood flooring is ready to be installed – but first Ryan must test to make sure that there has been no moisture penetration into the conc...
In this paper, we present a compilation of prominent findings of studies focused on mixture design, testing, and characterization, incorporation of waste and recycled materials, advances in computational modeling of pervious concrete materials, and finally, structural design of pervious concrete pavements...
PLC has undergone extensive testing and research in the U.S. and other countries to ensure its durability and resiliency. PLC also is simple to switch to as it is a 1:1 replacement for traditional portland cement. This allows users to continue their standard operations with minimal disruption ...
A full factorial experimental design was used to investigate the effects of the following variables on cylinder strength: end preparation (sulfur capping versus grinding), cylinder size (100 versus 150 mm diameter), type of testing machine (1.33-MN capacity versus 4.45-MN capacity), and nominal ...
In this paper, we systematically introduce research progress of the ISSC, with attentions to its compositions, fabrication methods, sensing signal testing methods, sensing properties and generation mechanism, and structural applications. Future challenges in the development and applications of the ISSC are...
